Today, we’re announcing Amazon Bedrock Managed Knowledge Base, a new set of capabilities that enables developers to build enterprise-grade generative AI applications with their proprietary data in minutes. Organizations building agentic AI applications need secure, reliable, and up-to-date access to enterprise-wide data to deliver accurate, fast, and trusted outcomes. Managed Knowledge Base abstracts away the complexity of building and managing retrieval-augmented generation (RAG) pipelines, allowing developers to focus on business outcomes rather than infrastructure management.

Developers building knowledge bases for their agents face three key challenges today:

• Connecting to enterprise data – Enterprise knowledge lives across disparate systems with different content types, access control lists, and document formats. Building and maintaining custom connectors for each source adds complexity that slows down development.
• Optimizing RAG accuracy – Best practices for retrieval-augmented generation keep evolving. Developers need to experiment with different parsing strategies, chunking approaches, embedding models, and agentic retrieval behaviors to get accurate answers from their data.
• Managing infrastructure at scale – Organizations need to serve large knowledge bases with millions of documents, or manage thousands of smaller knowledge bases across teams. Both patterns require reliable infrastructure, security enforcement, and cost control.

These challenges require developers to repeatedly perform undifferentiated work instead of focusing on their applications.

Amazon Bedrock Managed Knowledge Base addresses these challenges by abstracting away the multiple infrastructure components developers traditionally have to assemble and maintain themselves (storage, retrieval, embeddings, re-ranking, and foundation model selection) into a single managed primitive. By default, the service automatically selects and manages a default embeddings model, re-ranker model, and foundational model on your behalf, so you can get up to speed quickly without needing to pick or maintain one yourself. On top of this managed foundation, three core innovations further improve ease of use and accuracy:

• Native data connectors – Six pre-built ingestion connectors that natively pull enterprise data and permissions from SaaS applications, eliminating the overhead developers face in managing application-specific requirements. At launch, we support Amazon S3, SharePoint, Confluence, Web Crawler, Google Drive, and OneDrive.
• Smart Parsing – Different content types and sources require different approaches to achieve accurate retrieval. Smart Parsing handles this complexity automatically, selecting the right parsing strategy for each data type and connector to provide the highest accuracy for your agents.
• Agentic Retriever – Optimized for complex queries that require multiturn, multihop retrieval within a single knowledge base or across multiple knowledge bases. Agentic Retriever automatically infers end-user intent and draws relevant context from institutional knowledge spread across data sources and modalities.

With just a few lines of code, Amazon Bedrock Managed Knowledge Base automatically manages and scales the end-to-end RAG pipeline that powers your enterprise knowledge agents. For agent builders, it’s available as a pre-built target type in Amazon Bedrock AgentCore Gateway, reducing integration to a few lines of code, auto-generating role-based permissions, and providing observability and evaluation metrics in the AgentCore Observability dashboard.

Getting started with Amazon Bedrock Managed Knowledge Base

Creating a Managed Knowledge Base is straightforward. Navigate to the Amazon Bedrock AgentCore console or the Amazon Bedrock console, open the Knowledge Bases page, and choose Create Managed KB. The experience is the same in both consoles. You will see that Unstructured Vector Store KB is now available as the recommended option, alongside the other knowledge base types you may already be familiar with:

Picture 1 – Knowledge Bases list page in the Amazon Bedrock AgentCore console showing the Type column with different KB types and the Create Managed KB button

When creating a new Knowledge Bases, you can connect to your enterprise data sources by choosing from the list of supported connectors directly from a dropdown. AWS Identity and Access Management (IAM) roles are automatically created, and you can choose to edit these permissions if needed:

Picture 2 – Create Knowledge Base page showing the Data source dropdown expanded with all supported connectors: Amazon S3, Confluence, Custom, Google Drive, One Drive, SharePoint, and Web Crawler

An optimized set of defaults will be presented, allowing you to create your knowledge base in just a few clicks. Once the data is synced, you can integrate the knowledge base with your agent or provide it as a tool for your foundation model and start querying.

Smart Parsing for accurate data ingestion

One of the key challenges in building knowledge bases is preparing diverse data types for accurate retrieval. Once you point Managed Knowledge Base at your data sources, Smart Parsing automatically determines the optimal parsing strategy for each data type and connector, no extra configuration is required.

Smart Parsing combines multiple techniques:

• Connector-specific data models – Optimized handling for each data source. For example, the Web Crawler connector preserves HTML structure including embedded images and tables, ensuring rich content is not dropped during ingestion. SharePoint connectors maintain document hierarchy and relationships between files.
• Multimodal processing – Automatic detection and processing of different content types within documents. The system identifies bounding boxes in documents, then sends them to foundation models for data extraction, captioning, and scene description in video files.
• Optimized chunking – Smart Parsing leverages foundation models to understand document structure and extract meaningful content, ensuring that complex documents with mixed formats are properly indexed. Intelligent defaults balance retrieval accuracy with performance based on document type and content structure, while advanced users can customize chunking strategies when needed.

This automated approach eliminates weeks of experimentation typically required to achieve production-quality retrieval accuracy, while still preserving the flexibility to customize when needed.

Using Agentic Retriever for complex queries

After your data is ingested, you can start querying your knowledge base. Generative AI applications often struggle with complex user queries that require reasoning, recursive multi-step retrieval, and intermediate evaluations of results. Consider a user asking two related questions: “What is the cloud infrastructure budget for the ML platform team?” and “Does our expense policy allow prepaying annual commitments?” A single retrieval step might surface documents about the ML platform team but fail to connect the budget information with the expense policy needed to fully answer the question.

Picture 3 – Agentic Retriever decomposes complex user queries into a step-by-step plan, performing multi-hop retrieval across multiple knowledge bases and combining results to deliver accurate, grounded responses

Agentic Retriever solves this by creating a step-by-step query plan: 1. Which team owns the ML platform, and what is their cloud infrastructure budget? 2. What does the expense policy say about prepaying annual commitments? 3. Does the policy allow the ML platform team to prepay against this budget?

The system performs multi-hop retrieval and reasoning at each step, and once it has gathered sufficient relevant passages, it stops the search process and returns the top results. By abstracting away the complexity of building a separate multi-hop reasoning pipeline, this approach dramatically improves accuracy for complex queries while letting developers focus on their agentic search applications instead of orchestration logic.

You can try Agentic Retriever directly from the test panel of your knowledge base in the Amazon Bedrock AgentCore console. Select Agentic retrieval only as the retrieval type to let the system automatically plan and execute multi-step queries across your knowledge bases:

Picture 4 – Test Knowledge Base panel showing Agentic retrieval with answer generation selected as the retrieval type, with model selection and maximum agentic iterations options

Enabling MCP with Bedrock AgentCore

Amazon Bedrock Managed Knowledge Base seamlessly integrates with AgentCore Gateway as a native target type. This integration eliminates the need for manual integration and provides built-in observability, policy enforcement, and automatic permission management.

You can navigate to the Amazon Bedrock AgentCore console or SDK and create an AgentCore Gateway or select an existing one. When adding targets to your gateway, you will find Knowledge Base as a new pre-built target type alongside other options such as MCP server, Lambda ARN, REST API, and other integrations. Simply select your knowledge base ID to expose it through the gateway:

Picture 5 – Add targets page in AgentCore Gateway showing Knowledge Base as a new pre-built target type, with the knowledge base ID selector and runtime retrieval mode options

Add targets page in AgentCore Gateway showing Knowledge Base as a new pre-built target type, with the knowledge base ID selector and runtime retrieval mode options

Gateway exposes the standard Model Context Protocol (MCP), so the knowledge base tools are automatically discovered by clients from any MCP-compatible framework, including Strands Agents, LangChain, CrewAI, LlamaIndex, and LangGraph. No custom integration code is required.

Model choice and flexibility

Amazon Bedrock Managed Knowledge Base preserves the flexibility developers expect from Amazon Bedrock. Every foundation model available on Bedrock can power the generation step, and developers can select from different embedding and re-ranking models to optimize retrieval for their specific use case, enabling teams to fine-tune accuracy and cost-performance without changing infrastructure.

Unlike managed solutions that lock you into specific model providers, Amazon Bedrock Managed Knowledge Base separates the infrastructure management (connectors, parsing, storage, retrieval orchestration) from model selection. This means you can:

• Take advantage of the latest models – Adopt the latest embedding, re-ranking, and foundation models as they become available to improve accuracy, latency, and cost for your application without rebuilding your RAG pipeline.
• Optimize for price-performance – Choose smaller, faster models for simple queries and more capable models for complex reasoning tasks, all using the same knowledge base infrastructure.
• Use Bedrock embedding models – While Smart Parsing provides optimized defaults, you can configure Bedrock embedding models when your domain requires specialized semantic understanding.
• Maintain consistency with existing applications – If you’re already using Bedrock Knowledge Bases APIs (Retrieve, StartIngest, StopIngest, IngestKnowledgeBaseDocuments), Managed Knowledge Base uses the same APIs, so migration requires no code changes, just point to the new knowledge base ID.

This approach ensures you can spend time on your generative AI application without losing the ability to change models based on evolving requirements or new model capabilities.

Today, we’re announcing the general availability of Web Search on Amazon Bedrock AgentCore, a fully managed tool that enables agents to ground responses in current, cited web knowledge with zero data egress from customer’s secured AWS environment.

Web Search uses a built-in connector target on Bedrock AgentCore Gateway using the Model Context Protocol (MCP). Your agent sends a natural-language query, and Web Search returns most relevant snippets, source URLs, titles, and publication dates that the model can reason over to produce a grounded response.

It is built on Amazon’s search infrastructure, informed by years of experience powering agentic search experiences across Alexa+, Amazon Quick, and Kiro. It uses a multi-source grounding approach that combines Amazon’s web index with structured knowledge graph data. Beyond standard web results, this gives agents access to Amazon Knowledge Graph with verified facts, helping them retrieve more relevant and accurate responses than traditional web search alone.

With this launch, you can focus on building agents instead of manually adding web search to agents on Bedrock AgentCore and managing its infrastructure. Your AI agent looks at user question, retrieves the latest facts, and then takes any necessary action grounded in current developments beyond a model’s training data. You can also meet enterprise governance policies without sending user prompts and retrieval queries to external search API providers outside of AWS.

Web Search on Bedrock AgentCore in action

To get started, create the Bedrock AgentCore Gateway with Web Search tool target in the Bedrock AgentCore console. When the Gateway URL is created, you can interact with API call, Command Line Interface (CLI), or MCP Inspector.

To add Web Search tool target when creating the Gateway, choose MCP target as a target protocol and Connectors as a target type. You can select the Web Search tool as a preconfigured target to retrieve most relevant web search results including links, snippets, and metadata.

After creating your gateway, you can find the Web Search tool target on the detail page of your gateway. You can also add a new Web Search tool target to an existing gateway.

To interact with Web Search tool, use the sample invocation code in the View invocation code section. You can use code snippets through Python codes with API requests, MCP Python SDK, Strands MCP Client, and MCP Inspector.

For example, you can interact with the MCP Inspector, an interactive developer tool for testing and debugging MCP servers. When you connect to the MCP server through the Gateway resource URL, you will find a Web Search tool for each connector target on the Gateway. Enter input the web search query and choose Run Tool to get the results.

To learn more about how to use Web Search on Bedrock AgentCore, visit the Bedrock AgentCore Gateway documentation.

Today, we’re announcing the availability of Claude Fable 5 on Amazon Bedrock and Claude Platform on AWS. Claude Fable 5 makes Mythos-level capabilities available to customers, with strong safeguards designed to make it safe for broader use. Fable 5 is state-of-the-art on nearly all tested benchmarks and delivers exceptional performance in software engineering, knowledge work tasks, and vision – built for ambitious, long running work.

With Claude Fable 5 on Bedrock, you can build within your existing AWS environment and scale inference workloads. You can also use Claude Fable 5 through the Claude Platform on AWS, giving you Anthropic’s native platform experience.

According to Anthropic, Claude Fable 5 represents a step-change in what you can accomplish with AI models. Here is what makes this model different:

• Long-running, asynchronous execution — Claude Fable 5 handles complex tasks that previous models could not sustain, executing coding and knowledge work tasks for extended periods without intervention.
• Advanced vision capabilities — Claude Fable 5 understands diagrams, charts, and tables nested in files and PDFs. This opens up research and document-heavy work in finance, legal, analytics, architecture, and gaming. In coding, the model implements designs with high fidelity and uses vision to critique its output against goals.
• Proactive self-verification — The model self-updates skills based on learnings, develops its own harnesses and evaluations.

Claude Fable 5 includes safeguards that limit its performance in specific areas where misuse risk is elevated. Harmful prompts related to cybersecurity, biology, chemistry, and health fall back to receive a response from Opus 4.8 instead. Anthropic is able to expand access to nearly all of Claude Fable 5’s state-of-the-art capabilities by developing more powerful safeguards. The same model without these limits is Claude Mythos 5 and it will only be available to a small group of vetted customers.

Claude Fable 5 model in action

You can use Claude Fable 5 in both Amazon Bedrock and Claude Platform on AWS. This post will cover guidance on how to access and use on Amazon Bedrock. For guidance on the Claude Platform on AWS, visit the documentation to learn more.

To get started with Amazon Bedrock, you can access the model programmatically now using the Anthropic Messages API to call the bedrock-runtime or bedrock-mantle endpoints through Anthropic SDK. You can also keep using the Invoke and Converse API on bedrock-runtime through the AWS Command Line Interface (AWS CLI) and AWS SDK.

In order to access Claude Fable 5 model, you must opt into data sharing by using the Data Retention API and setting provider_data_share before you can invoke the models. There is no console user interface for this setting at launch.

Here is a sample script to set data retention for bedrock-mantle engine.

curl -X PUT https://bedrock-mantle.us-east-1.api.aws/v1/data_retention 
  -H "x-api-key: <your-bedrock-api-key>"  
  -H "Content-Type: application/json" 
  -d '{ "mode": "provider_data_share" }'

If you want to use bedrock-runtime engine, run this sample script.

curl -X PUT https://bedrock.us-east-1.amazonaws.com/data-retention 
  -H "Authorization: Bearer <your_bearer_token>" 
  -H "Content-Type: application/json" 
  -d '{ "mode": "provider_data_share" }'

This mode allows Amazon Bedrock to retain and share your inference data with model providers per their requirements. Anthropic requires 30-day inputs and outputs retention, as well as human review. To learn more, visit the Amazon Bedrock abuse detection.

Let’s start with Anthropic SDK for Python using the Messages API on bedrock-mantle endpoint. Install Anthropic SDK.

pip install anthropic

Here is a sample Python code to call Claude Fable 5 model:

import anthropic

client = anthropic.Anthropic(
    base_url="https://bedrock-mantle.us-east-1.api.aws/anthropic",
    api_key= <your-bedrock-api-key>
)

message = client.messages.create( 
     model="anthropic.claude-fable-5", 
	 max_tokens=4096, 
	 messages=[ 
	     { "role": "user", 
		   "content": "Design a distributed architecture on AWS in Python that should support 100k requests per second across multiple geographic regions", 
		 }, 
	 ], 
)

print(message.content[0].text)

To learn more, check out Anthropic Messages API code examples and notebook examples for multiple use cases and a variety of programming languages.

You can use Claude Fable 5 in the Bedrock console. Choose Claude Fable 5 in the Playground and test it.

You can also use Claude Fable 5 with the Invoke API and Converse API on bedrock-runtime endpoint. Here’s a example to call Converse API for a unified multi-model experience using the AWS SDK for Python (Boto3):

import boto3 
bedrock_runtime = boto3.client("bedrock-runtime", region_name="us-east-1") 
response = bedrock_runtime.converse( 
    modelId="global.anthropic.claude-fable-5", 
    messages=[ 
        { 
            "role": "user", 
            "content": [ 
                { 
                    "text": "Design a distributed architecture on AWS in Python that should support 100k requests per second across multiple geographic regions." 
                } 
            ] 
        } 
    ], 
    inferenceConfig={ 
        "maxTokens": 4096 
    } 
) 
print(response["output"]["message"]["content"][0]["text"]) 

To learn more, visit code examples that show how to use Amazon Bedrock Runtime with AWS SDKs.

Things to know

Let me share some important technical details that I think you’ll find useful.

• Model access — Claude Fable 5 access is gradually expanding for all AWS accounts. If your account doesn’t have access yet, it will be enabled soon depending on your Bedrock usage. If you want to get access to this model quickly, contact your usual AWS Support.
• Pricing — When a harmful prompt is routed to Opus 4.8 instead of Fable 5, you pay only Opus prices. If a request is blocked mid-conversation, initial tokens are charged at Fable rates and subsequent tokens at Opus rates. To learn more, visit the Amazon Bedrock pricing page.
• Data retention — For Fable 5, Mythos 5, and future models on Bedrock with similar or higher capability levels, Anthropic will require 30-day retention for all traffic on Mythos-class models. Retaining data for a limited period allows Anthropic to detect patterns of misuse that are not visible from a single exchange. Once you opt into data retention, your data will leave AWS’s data and security boundary.
• Claude Mythos 5 on Bedrock (Limited Preview) — You can also use Anthropic’s most capable model for cybersecurity and life sciences, including vulnerability discovery, drug design, and biodefense screening. Access is currently limited due to the dual-use nature of these domains. To learn more, visit the model card documentation.

Now available

Anthropic’s Claude Fable 5 model is available today on Amazon Bedrock in the US East (N. Virginia) and Europe (Stockholm) Regions; check the full list of Regions for future updates. Claude Fable 5 is also available on the Claude Platform on AWS in North America, South America, Europe, and Asia Pacific.

Give Claude Fable 5 a try with the Amazon Bedrock APIs, in the Claude Platform on AWS, and send feedback to AWS re:Post for Amazon Bedrock or through your usual AWS Support contacts.

Today, we’re announcing a new console experience in Amazon Bedrock for you to experiment, iterate, and scale with the latest AI models on Amazon Bedrock’s next-generation inference engine built for high performance, reliability, and security. This console has a refreshed workflow optimized for bedrock-mantle endpoint, which supports the latest GPT, Claude, and open-weight models with the OpenAI Responses API, OpenAI Chat Completions API, and the Anthropic Messages API.

The new console experience makes it simple to find the right model and move quickly from evaluation to production.

• New model card – You can browse the full model catalog, compare them side by side on capabilities, modality support, context window, and applicable service quotas in a single view, removing the need to stitch together documentation, and limit calculators.
• Project-based work – You can make a project to run evaluations and review usage insights in one streamlined workflow that mirrors the lifecycle of building a generative AI application.
• Live documentation – You can use project-aware live documentation: code samples, SDK snippets, and API references are automatically prefilled with your project variables. You can copy a snippet straight from the console into your application and run it without modification.

How to get started

You can try a new experience by choosing Try the Bedrock Mantle Console from within the Amazon Bedrock console, or by using the new console link directly.

You can find a project-based dashboard to show inference requests and error by range of recent dates, recently used models, and the project list. You can create a project, assign models, configure API keys, and start making inference requests in minutes.

A new model catalog shows the latest GPT, Claude, and open-weight models that are supported on the bedrock-mantle engine. You can see the details of features, tokens, pricing, input/output, pricing information, and Regional availability. You can also compare up to 3 models in a single view.

When you choose the project dashboard, you can see the models used in the project, the distribution of your token usage such as total token usage, token usage per minute, inference requests per minute, and tokens per inference request. This can inform your model selection, prompt optimization, and workload consistency decisions.

You can select up to 3 models to start evaluating to compare responses side by side with the same prompt.

To build your application in the project, choose Getting started. You can migrate existing code, build a new app with the Anthropic or OpenAI SDK, or connect an AI coding assistant to Bedrock.

Choose the API & SDK, your SDK (either Anthropic or OpenAI), your preferred programming language, and your authentication method. It shows your environment code to run these in your terminal for a quick test, or save to a .env file for your application. You can also send your first request with sample code snippets to verify your setup.

When you choose Clients, you can select the AI coding agent source such as Claude Code, Cline, Codex, Cursor, or OpenCode that you want to connect to the bedrock-mantle engine. It provides instructions on how to install the AI agent, use your AWS IAM credentials or use a Bedrock API key, set environment variables, and route requests from each AI agent through Bedrock.

To learn about Anthropic- and OpenAI-compatible APIs, choose Live API docs. You can choose Anthropic API Protocol for access to Claude model features like the Messages API or OpenAI API Protocol for access to features like Responses API.

For example, when you choose OpenAI Response API, it retrieves a model response with the given model ID. These API references are automatically prefilled with the project’s selected model ID, Region, bedrock-mantle endpoint URL, and API key reference, and they update in place as you change models or settings.

You can also choose the existing Bedrock console to manage fully-managed features such as Agents, Knowledge Bases, Guardrails, fine-tuning, or the InvokeModel and Converse APIs to run on the bedrock-runtime endpoint.

Now available

The new console experience is available in all AWS Regions where the bedrock-mantle endpoint is offered: US East (N. Virginia, Ohio), US West (Oregon), Asia Pacific (Jakarta, Mumbai, Sydney, Tokyo), Europe (Frankfurt, Ireland, London, Milan, Stockholm), and South America (São Paulo).

As we previewed in What’s Next with AWS 2026, we’re announcing the general availability of OpenAI GPT-5.5, GPT-5.4 models, and Codex on Amazon Bedrock, giving you access to frontier models and a coding agent for software development.

According to OpenAI, GPT-5.5 and GPT-5.4 models are excellent for coding, reasoning, agentic workflows, and complex professional work. You can use GPT-5.5 for the hardest customer workloads and GPT-5.4 for the best price-performance. You can call them through Responses API on Amazon Bedrock’s next-generation inference engine built for high performance, reliability, and security.

Codex is the OpenAI coding agent for AI-powered software development. According to OpenAI, more than 4 million developers use Codex every week to write, refactor, debug, test, and validate code across large codebases. With GPT-5.5 powering inference, Codex introduces a new class of intelligence optimized for complex, long-horizon developer workflows. You can use the Codex App, the Codex CLI, and IDE integrations with Visual Studio Code, JetBrains, and Xcode, with all model inference routed through the Responses API on Amazon Bedrock.

For customers with data residency requirements, all processing stays within the Bedrock Region you select. You pay per token with no seat licenses and no per-developer commitments.

GPT-5.5 and GPT-5.4 models on Bedrock in action

You can access the model programmatically using the OpenAI Responses API to call the bedrock-mantle endpoints through the OpenAI SDK, command-line tools such as curl.

Let’s start with OpenAI SDK for Python. Install OpenAI SDK.

pip install -U openai

Set the environment variables for authentication.

export OPENAI_BASE_URL="https://bedrock-mantle.us-east-2.api.aws/openai/v1"
export OPENAI_API_KEY="<BEDROCK_API_KEY>"
export BEDROCK_OPENAI_MODEL_ID="openai.gpt-5.5"

Here is a sample Python code to call GPT-5.5 model on Bedrock:

import os
from openai import OpenAI
 
client = OpenAI(
    base_url=os.environ["OPENAI_BASE_URL"],
    api_key=os.environ["OPENAI_API_KEY"],
)
 
response = client.responses.create(
    model=os.environ["BEDROCK_OPENAI_MODEL_ID"],
    input=[
        {
            "role": "developer",
            "content": "You are a software engineer with excellent AWS cloud knowledge. Be concise and practical.",
        },
        {
            "role": "user",
            "content": "Design a distributed architecture on AWS in Python that should support 100k requests per second across multiple geographic regions.",
        },
    ],
    reasoning={"effort": "medium"},
    text={"verbosity": "low"},
)
 
print(response.output_text)

You can call directly the model endpoint using curl.

curl "$OPENAI_BASE_URL/responses" 
  -H "Content-Type: application/json" 
  -H "Authorization: Bearer $OPENAI_API_KEY" 
  -d '{
    "model": "openai.gpt-5.5",
    "input": [
      {
        "role": "developer",
        "content": "You are a software engineer with excellent AWS cloud knowledge."
      },
      {
        "role": "user",
        "content": "Design a distributed architecture on AWS in Python that should support 100k requests per second across multiple geographic regions."
      }
    ],
    "reasoning": {"effort": "medium"},
    "text": {"verbosity": "low"}
  }'

You can use the Responses API when you want to use model-managed multi-turn state, need hosted tools, function tools, or richer tool orchestration, and run background or long-running work. To learn more, visit the OpenAI Cookbook Responses examples and getting started guide.

Using OpenAI Codex with GPT-5.5 on Amazon Bedrock

You can download Codex CLI, Codex App or Codex VS Code extension and get started with the Bedrock for model inference. Codex supports two Bedrock authentication pathways: Amazon Bedrock API key or AWS SDK credential chain. If you set AWS_BEARER_TOKEN_BEDROCK, Codex uses it first; otherwise Codex falls back to AWS SDK credential chain.

Set AWS_BEARER_TOKEN_BEDROCK in the environment that Codex will read:

export AWS_BEARER_TOKEN_BEDROCK=<your-bedrock-api-key>

Then, configure your preferred Region and set the model ID to openai.gpt-5.5 in ~/.codex/config.toml, which is required for Bedrock API-key authentication. You can also choose openai.gpt-5.4, openai.gpt-oss-120b, or openai.gpt-oss-20b. For the desktop app or VS Code extension, put any environment variables the app needs in ~/.codex/.env.

model = "openai.gpt-5.5"
model_provider = "amazon-bedrock"
[model_providers.amazon-bedrock.aws]
region = "us-east-2"

Restart the desktop app or VS Code extension after changing ~/.codex/config.toml or ~/.codex/.env. In Codex CLI, you should see a /status tab that looks like this:

In Codex App, you can use GPT-5.5 model through Amazon Bedrock inference.

To learn more about how to configure Codex to use OpenAI models on Amazon Bedrock, visit Use Codex with Amazon Bedrock.

Things to know

Let me share some important technical details that I think you’ll find useful.

• Model latency: OpenAI model information positions GPT-5.5 as fast and GPT-5.4 as medium speed, but customer-perceived latency depends on reasoning effort, output length, tool calls, background mode, Region, quotas, throttling, prompt size, and cache hits. Start GPT-5.5 at medium effort. Start GPT-5.4 with effort set explicitly rather than relying on its none default.
• Scaling and capacity: Bedrock’s new inference engine is designed to rapidly provision and serve capacity across many different models. When accepting requests, we prioritize keeping steady state workloads running, and ramp usage and capacity rapidly in response to changes in demand. During periods of high demand, requests are queued, rather than rejected.

Updated on June, 1, 2026 – The GPT models now support the Responses API only on Amazon Bedrock, and console support is coming soon.

The post Get started with OpenAI GPT-5.5, GPT-5.4 models, and Codex on Amazon Bedrock appeared first on The NOKIA Blog.

Today, we’re announcing Amazon Bedrock Advanced Prompt Optimization, a new tool that you can use to optimize your prompts for any model on Amazon Bedrock, while comparing your original prompts to optimized prompts across up to 5 models simultaneously. With the new prompt optimization, you can migrate to a new model or improve performance from your current model. You can test them to make sure they see no regressions on known use cases and also improve on underperforming tasks.

The new prompt optimizer takes in your prompt template, example user inputs for the variable values, ground truth answers, and an evaluation metric to use as a guide. You can even use this with multimodal user inputs – it supports png, jpg, and pdf as inputs to your prompt templates so you can optimize prompts for tasks like document and image analysis.

You can also provide an AWS Lambda function, LLM-as-a-judge rubric, or a short natural language description to guide the optimization. The prompt optimizer works in a metric-driven feedback loop to optimize the prompt and resulting model responses for the evaluation metric, and outputs the original and final prompt templates with evaluation scores, cost estimates, and latency.

Bedrock Advanced Prompt Optimization in action

To get started with the new prompt optimization, choose Create prompt optimization on the Advanced Prompt Optimization page of Amazon Bedrock console.

Pick up to 5 inference models for which to optimize your prompts. You can use this if you are migrating to a new model or just want to get better performance on their current model. If you’re changing models, you can select your current model as a baseline and up to 4 other models. If you aren’t changing models, then just select your current model to see before and after optimization.

You should prepare your prompt templates in JSONL format with example user data, ground truth answers, and an evaluation metric or rewriting guidance. For .jsonl files, each JSON object must be on a single line.

{
    "version": "bedrock-2026-05-14",           // required; Fixed value
    "templateId": "string",                    // required
    "promptTemplate": "string",                // required
    "steeringCriteria": ["string"],            // optional
    "customEvaluationMetricLabel": "string",   // required if customLLMJConfig or evaluationMetricLambdaArn is used
    "customLLMJConfig": {                      // optional
        "customLLMJPrompt": "string",          // required if customLLMJConfig present
        "customLLMJModelId": "string"          // required if customLLMJConfig present
    },
    "evaluationMetricLambdaArn": "string",     // optional
    "evaluationSamples": [                     // required
        {
            "inputVariables": [                // required
                {
                    "variableName1": "string",
                    "variableName2": "string"
                }
            ],
            "referenceResponse": "string"      // optional
            "inputVariablesMultimodal": [      // optional
                {
                "Arbitrary_Name": {            // required for your multimodal variable.
                    "type": "string",          // choose from "PDF" or "IMAGE". Acceptable filetypes for IMAGE = png, jpg,  
                    "s3Uri": "string"          // input the S3 path of the file
                }
            ]
        }
    ]
}

You can upload files directly or import prompt templates from Amazon Simple Storage Service (Amazon S3) and set an S3 output location where prompt optimization results and evaluation data will be stored. Then, choose Create optimization.

Amazon Bedrock automatically sends your prompt templates and example data with optional ground truth to your inference models, evaluates the responses with your evaluation metric, then rewrites the prompt in a feedback loop to optimize it for your inference models. You’ll see evaluation results based on your provided metric and your final optimized prompts.

As you noted, you can evaluate prompt quality in three ways: a Lambda function with your own Python scoring logic, LLM-as-a-Judge with a custom rubric, or natural-language steering criteria. You can just choose one per prompt template, but can do multiple prompt templates in a job, so they can use a different method for each prompt template if they want.

• Lambda function — If you have a concrete metric (accuracy, F1, execution accuracy, structured-JSON match, etc.), you can deploy a Lambda function containing your custom scoring logic and configure evaluationMetricS3Uri field of the prompt template. Inside the Lambda, the core is a compute_score implementation that programmatically compares model outputs against reference responses.
• LLM-as-a-Judge — If your task is open-ended (summarization, generation, reasoning explanations) and you want a rubric-based score, you can configure the S3 config file in the customLLMJConfig field of the prompt template to define named metrics with structured instructions and a rating scale. A Bedrock judge model evaluates each prompt-response pair and returns a score with reasoning. The default model is Claude Sonnet 4.6 and you can also select your own from a list of judge models.
• Steering criteria — If you know the qualities you want (brand voice, format, safety constraints) but don’t want to author a full judge prompt, you can define criteria in the input dataset through the steeringCriteria array of the prompt template. Instead of structured metrics with rating scales, you provide free-form natural language criteria that the LLM judge evaluates holistically. If you use this option, then a default LLM-as-a-judge prompt will evaluate the responses and incorporate your steering criteria into the judge prompt. The judge model in this case is Anthropic Claude Sonnet 4.6.

The post AWS Weekly Roundup: Amazon Bedrock AgentCore payments, Agent Toolkit for AWS, and more (May 11, 2026) appeared first on The NOKIA Blog.

Today, we’re announcing Claude Opus 4.7 in Amazon Bedrock, Anthropic’s most intelligent Opus model for advancing performance across coding, long-running agents, and professional work.

Claude Opus 4.7 is powered by Amazon Bedrock’s next generation inference engine, delivering enterprise-grade infrastructure for production workloads. Bedrock’s new inference engine has brand-new scheduling and scaling logic which dynamically allocates capacity to requests, improving availability particularly for steady-state workloads while making room for rapidly scaling services. It provides zero operator access—meaning customer prompts and responses are never visible to Anthropic or AWS operators—keeping sensitive data private.

According to Anthropic, Claude Opus 4.7 model provides improvements across the workflows that teams run in production such as agentic coding, knowledge work, visual understanding,long-running tasks. Opus 4.7 works better through ambiguity, is more thorough in its problem solving, and follows instructions more precisely.

• Agentic coding: The model extends Opus 4.6’s lead in agentic coding, with stronger performance on long-horizon autonomy, systems engineering, and complex code reasoning tasks. According to Anthropic, the model records high-performance scores with 64.3% on SWE-bench Pro, 87.6% on SWE-bench Verified, and 69.4% on Terminal-Bench 2.0.
• Knowledge work: The model advances professional knowledge work, with stronger performance on document creation, financial analysis, and multi-step research workflows. The model reasons through underspecified requests, making sensible assumptions and stating them clearly, and self-verifies its output to improve quality on the first step. According to Anthropic, the model reaches 64.4% on Finance Agent v1.1.
• Long-running tasks: The model stays on track over longer horizons, with stronger performance over its full 1M token context window as it reasons through ambiguity and self-verifies its output.
• Vision: the model adds high-resolution image support, improving accuracy on charts, dense documents, and screen UIs where fine detail matters.

The model is an upgrade from Opus 4.6 but may require prompting changes and harness tweaks to get the most out of the model. To learn more, visit Anthropic’s prompting guide.

Claude Opus 4.7 model in action

You can get started with Claude Opus 4.7 model in Amazon Bedrock console. Choose Playground under Test menu and choose Claude Opus 4.7 when you select model. Now, you can test your complex coding prompt with the model.

I run the following prompt example about technical architecture decision:

Design a distributed architecture on AWS in Python that should support 100k requests per second across multiple geographic regions.

You can also access the model programmatically using the Anthropic Messages API to call the bedrock-runtime through Anthropic SDK or bedrock-mantle endpoints, or keep using the Invoke and Converse API on bedrock-runtime through the AWS Command Line Interface (AWS CLI) and AWS SDK.

To get started with making your first API call to Amazon Bedrock in minutes, choose Quickstart in the left navigation pane in the console. After choosing your use case, you can generate a short term API key to authenticate your requests as testing purpose.

When you choose the API method such as the OpenAI-compatible Responses API, you can get sample codes to run your prompt to make your inference request using the model.

To invoke the model through the Anthropic Claude Messages API, you can proceed as follows using anthropic[bedrock] SDK package for a streamlined experience:

from anthropic import AnthropicBedrockMantle
# Initialize the Bedrock Mantle client (uses SigV4 auth automatically)
mantle_client = AnthropicBedrockMantle(aws_region="us-east-1")
# Create a message using the Messages API
message = mantle_client.messages.create(
    model="us.anthropic.claude-opus-4-7",
    max_tokens=32000,
    messages=[ 
	    {"role": "user", "content": "Design a distributed architecture on AWS in Python that should support 100k requests per second across multiple geographic regions"}
    ]
)
print(message.content[0].text)

You can also run the following command to invoke the model directly to bedrock-runtime endpoint using the AWS CLI and the Invoke API:

aws bedrock-runtime invoke-model  
 --model-id us.anthropic.claude-opus-4-7  
 --region us-east-1  
 --body '{"anthropic_version":"bedrock-2023-05-31", "messages": [{"role": "user", "content": "Design a distributed architecture on AWS in Python that should support 100k requests per second across multiple geographic regions."}], "max_tokens": 32000}'  
 --cli-binary-format raw-in-base64-out  
invoke-model-output.txt

For more intelligent reasoning capability, you can use Adaptive thinking with Claude Opus 4.7, which lets Claude dynamically allocate thinking token budgets based on the complexity of each request.

To learn more, visit the Anthropic Claude Messages API and check out code examples for multiple use cases and a variety of programming languages.

Things to know

Let me share some important technical details that I think you’ll find useful.

• Choosing APIs: You can choose from a variety of Bedrock APIs for model inference, as well as the Anthropic Messages API. The Bedrock-native Converse API supports multi-turn conversations and Guardrails integration. The Invoke API provides direct model invocation and lowest-level control.
• Scaling and capacity: Bedrock’s new inference engine is designed to rapidly provision and serve capacity across many different models. When accepting requests, we prioritize keeping steady state workloads running, and ramp usage and capacity rapidly in response to changes in demand. During periods of high demand, requests are queued, rather than rejected. Up to 10,000 requests per minute (RPM) per account per Region are available immediately, with more available upon request.

Now available

Anthropic’s Claude Opus 4.7 model is available today in the US East (N. Virginia), Asia Pacific (Tokyo), Europe (Ireland), and Europe (Stockholm) Regions; check the full list of Regions for future updates. To learn more, visit the Claude by Anthropic in Amazon Bedrock page and the Amazon Bedrock pricing page.

Updated on April 17, 2026 – We fixed code samples and CLI commends to align new version.

The post Introducing Anthropic’s Claude Opus 4.7 model in Amazon Bedrock appeared first on The NOKIA Blog.

Today, we’re announcing the general availability of cross-account safeguards in Amazon Bedrock Guardrails, a new capability that enables centralized enforcement and management of safety controls across multiple AWS accounts within an organization.

With this new capability, you can specify a guardrail in a new Amazon Bedrock policy within the management account of your organization that automatically enforces configured safeguards across all member entities for every model invocation with Amazon Bedrock. This organization-wide implementation supports uniform protection across all accounts and generative AI applications with centralized control and management. This capability also offers flexibility to apply account-level and application-specific controls depending on use case requirements in addition to organizational safeguards.

• Organization-level enforcements apply a single guardrail from your organization’s management account to all entities within the organization through policy settings. This guardrail automatically enforces filters across all member entities, including organizational units (OUs) and individual accounts, for all Amazon Bedrock model invocations.
• Account-level enforcement enables automatic enforcement of configured safeguards across all Amazon Bedrock model invocations in your AWS account. The configured safeguards in the account-level guardrail apply to all inference API calls.

You can now establish and centrally manage dependable, comprehensive protection through a single, unified approach. This supports consistent adherence to corporate responsible AI requirements while significantly reducing the administrative burden of monitoring individual accounts and applications. Your security team no longer needs to oversee and verify configurations or compliance for each account independently.

Getting started with centralized enforcement in Amazon Bedrock Guardrails

You can get started with account-level and organization-level enforcement configuration in the Amazon Bedrock Guardrails console. Before the enforcement configuration, you need to create a guardrail with a particular version to support the guardrail configuration remains immutable and cannot be modified by member accounts and complete prerequisites for using the new capability such as resource-based policies for guardrails.

To enable account-level enforcement, choose Create in the section of Account-level enforcement configurations.

You can choose the guardrail and version to automatically apply to all Bedrock inference calls from this account in this Region. With general availability, we introduce the new feature defining which models will be affected by the enforcement with either Include or Exclude behavior.

You can also configure selective content guarding controls for system prompts and user prompts with either Comprehensive or Selective.

• Use Comprehensive when you want to enforce guardrails on everything, regardless of what the caller tags. This is the safer default when you don’t want to rely on callers to correctly identify sensitive content.
• Use Selective when you trust callers to tag the right content and want to reduce unnecessary guardrail processing. This is useful when callers handle a mix of pre-validated and user-generated content, and only need guardrails applied to specific portions.

After creating the enforcement, you can test and verify enforcement using a role in your account. The account-enforced guardrail should automatically apply to both prompts and outputs.

Check the response for guardrail assessment information. The guardrail response will include enforced guardrail information. You can also test by making a Bedrock inference call using InvokeModel, InvokeModelWithResponseStream, Converse, or ConverseStream APIs.

To enable organization-level enforcement, go to AWS Organizations console and choose Policies menu. You can enable the Bedrock policies in the console.

You can create a Bedrock policy that specifies your guardrail and attach it to your target accounts or OUs. Choose Bedrock policies enabled and Create policy. Specify your guardrail ARN and version and configure the input tags setting for in the AWS Organizations. To learn more, visit Amazon Bedrock policies in AWS Organizations and Amazon Bedrock policy syntax and examples.

After creating the policy, you can attach the policy to your desired organizational units, accounts, root in the Targets tab.

Search and select your organization root, OUs, or individual accounts to attach your policy, and choose Attach policy.

You can test that the guardrail is being enforced on member accounts and verify which guardrail is enforced. From a member account attached, you should see the organization enforced guardrail under the section Organization-level enforcement configurations.

The underlying safeguards within the specified guardrail are then automatically enforced for every model inference request across all member entities, ensuring consistent safety controls. To accommodate varying requirements of individual teams or applications, you can attach different policies with associated guardrails to different member entities through your organization.

Things to know

Here are key considerations to know about GA features:

• You can now choose to include or exclude specific models in Bedrock for inference, enabling centralized enforcement on model invocation calls. You can also choose to safeguard partial or complete system prompts and input prompts. To learn more, visit Apply cross-account safeguards with Amazon Bedrock Guardrails enforcement.
• Ensure you are specifying the accurate guardrail Amazon Resource Names (ARN) in the policy. Specifying an incorrect or invalid ARN will result in policy violations, non-enforcement of safeguards, and the inability to use the models in Amazon Bedrock for inference. To learn more, visit Best practices for using Amazon Bedrock policies.
• Automated Reasoning checks are not supported with this capability.

Now available

Cross-account safeguards in Amazon Bedrock Guardrails is generally available today in the all AWS commercial and GovCloud Regions where Bedrock Guardrails is available. For Regional availability and a future roadmap, visit the AWS Capabilities by Region. Charges apply to each enforced guardrail according to its configured safeguards. For detailed pricing information on individual safeguards, visit Amazon Bedrock Pricing page.

Give this capability a try in the Amazon Bedrock console and send feedback to AWS re:Post for Amazon Bedrock Guardrails or through your usual AWS Support contacts.

Organizations face a challenging trade-off when adapting AI models to their specific business needs: settle for generic models that produce average results, or tackle the complexity and expense of advanced model customization. Traditional approaches force a choice between poor performance with smaller models or the high costs of deploying larger model variants and managing complex infrastructure. Reinforcement fine-tuning is an advanced technique that trains models using feedback instead of massive labeled datasets, but implementing it typically requires specialized ML expertise, complicated infrastructure, and significant investment—with no guarantee of achieving the accuracy needed for specific use cases.

Today, we’re announcing reinforcement fine-tuning in Amazon Bedrock, a new model customization capability that creates smarter, more cost-effective models that learn from feedback and deliver higher-quality outputs for specific business needs. Reinforcement fine-tuning uses a feedback-driven approach where models improve iteratively based on reward signals, delivering 66% accuracy gains on average over base models.

Amazon Bedrock automates the reinforcement fine-tuning workflow, making this advanced model customization technique accessible to everyday developers without requiring deep machine learning (ML) expertise or large labeled datasets.

How reinforcement fine-tuning works

Reinforcement fine-tuning is built on top of reinforcement learning principles to address a common challenge: getting models to consistently produce outputs that align with business requirements and user preferences.

While traditional fine-tuning requires large, labeled datasets and expensive human annotation, reinforcement fine-tuning takes a different approach. Instead of learning from fixed examples, it uses reward functions to evaluate and judge which responses are considered good for particular business use cases. This teaches models to understand what makes a quality response without requiring massive amounts of pre-labeled training data, making advanced model customization in Amazon Bedrock more accessible and cost-effective.

Here are the benefits of using reinforcement fine-tuning in Amazon Bedrock:

• Ease of use – Amazon Bedrock automates much of the complexity, making reinforcement fine-tuning more accessible to developers building AI applications. Models can be trained using existing API logs in Amazon Bedrock or by uploading datasets as training data, eliminating the need for labeled datasets or infrastructure setup.
• Better model performance – Reinforcement fine-tuning improves model accuracy by 66% on average over base models, enabling optimization for price and performance by training smaller, faster, and more efficient model variants. This works with Amazon Nova 2 Lite model, improving quality and price performance for specific business needs, with support for additional models coming soon.
• Security – Data remains within the secure AWS environment throughout the entire customization process, mitigating security and compliance concerns.

The capability supports two complementary approaches to provide flexibility for optimizing models:

• Reinforcement Learning with Verifiable Rewards (RLVR) uses rule-based graders for objective tasks like code generation or math reasoning.
• Reinforcement Learning from AI Feedback (RLAIF) employs AI-based judges for subjective tasks like instruction following or content moderation.

Getting started with reinforcement fine-tuning in Amazon Bedrock

Let’s walk through creating a reinforcement fine-tuning job.

First, I access the Amazon Bedrock console. Then, I navigate to the Custom models page. I choose Create and then choose Reinforcement fine-tuning job.

I start by entering the name of this customization job and then select my base model. At launch, reinforcement fine-tuning supports Amazon Nova 2 Lite, with support for additional models coming soon.

Next, I need to provide training data. I can use my stored invocation logs directly, eliminating the need to upload separate datasets. I can also upload new JSONL files or select existing datasets from Amazon Simple Storage Service (Amazon S3). Reinforcement fine-tuning automatically validates my training dataset and supports the OpenAI Chat Completions data format. If I provide invocation logs in the Amazon Bedrock invoke or converse format, Amazon Bedrock automatically converts them to the Chat Completions format.

The reward function setup is where I define what constitutes a good response. I have two options here. For objective tasks, I can select Custom code and write custom Python code that gets executed through AWS Lambda functions. For more subjective evaluations, I can select Model as judge to use foundation models (FMs) as judges by providing evaluation instructions.

Here, I select Custom code, and I create a new Lambda function or use an existing one as a reward function. I can start with one of the provided templates and customize it for my specific needs.

I can optionally modify default hyperparameters like learning rate, batch size, and epochs.

For enhanced security, I can configure virtual private cloud (VPC) settings and AWS Key Management Service (AWS KMS) encryption to meet my organization’s compliance requirements. Then, I choose Create to start the model customization job.

During the training process, I can monitor real-time metrics to understand how the model is learning. The training metrics dashboard shows key performance indicators including reward scores, loss curves, and accuracy improvements over time. These metrics help me understand whether the model is converging properly and if the reward function is effectively guiding the learning process.

When the reinforcement fine-tuning job is completed, I can see the final job status on the Model details page.

Once the job is completed, I can deploy the model with a single click. I select Set up inference, then choose Deploy for on-demand.

Here, I provide a few details for my model.

After deployment, I can quickly evaluate the model’s performance using the Amazon Bedrock playground. This helps me to test the fine-tuned model with sample prompts and compare its responses against the base model to validate the improvements. I select Test in playground.

The playground provides an intuitive interface for rapid testing and iteration, helping me confirm that the model meets my quality requirements before integrating it into production applications.

Interactive demo

Learn more by navigating an interactive demo of Amazon Bedrock reinforcement fine-tuning in action.

Additional things to know

Here are key points to note:

• Templates — There are seven ready-to-use reward function templates covering common use cases for both objective and subjective tasks.
• Pricing — To learn more about pricing, refer to the Amazon Bedrock pricing page.
• Security — Training data and custom models remain private and aren’t used to improve FMs for public use. It supports VPC and AWS KMS encryption for enhanced security.

Get started with reinforcement fine-tuning by visiting the reinforcement fine-tuning documentation and by accessing the Amazon Bedrock console.

Happy building!

Today, we’re announcing new capabilities in Amazon Bedrock AgentCore to further remove barriers holding AI agents back from production. Organizations across industries are already building on AgentCore, the most advanced agentic platform to build, deploy, and operate highly capable agents securely at any scale. In just 5 months since preview, the AgentCore SDK has been downloaded over 2 million times. For example:

• PGA TOUR, a pioneer and innovation leader in sports has built a multi-agent content generation system to create articles for their digital platforms. The new solution, built on AgentCore, enables the PGA TOUR to provide comprehensive coverage for every player in the field, by increasing content writing speed by 1,000 percent while achieving a 95 percent reduction in costs.
• Independent software vendors (ISVs) like Workday are building the software of the future on AgentCore. AgentCore Code Interpreter provides Workday Planning Agent with secure data protection and essential features for financial data exploration. Users can analyze financial and operational data through natural language queries, making financial planning intuitive and self-driven. This capability reduces time spent on routine planning analysis by 30 percent, saving approximately 100 hours per month.
• Grupo Elfa, a Brazilian distributor and retailer, relies on AgentCore Observability for complete audit traceability and real-time metrics of their agents, transforming their reactive processes into proactive operations. Using this unified platform, their sales team can handle thousands of daily price quotes while the organization maintains full visibility of agent decisions, helping achieve 100 percent traceability of agent decisions and interactions, and reduced problem resolution time by 50 percent.

As organizations scale their agent deployments, they face challenges around implementing the right boundaries and quality checks to confidently deploy agents. The autonomy that makes agents powerful also makes them hard to confidently deploy at scale, as they might access sensitive data inappropriately, make unauthorized decisions, or take unexpected actions. Development teams must balance enabling agent autonomy while ensuring they operate within acceptable boundaries and with the quality you require to put them in front of customers and employees.

The new capabilities available today take the guesswork out of this process and help you build and deploy trusted AI agents with confidence:

• Policy in AgentCore (Preview) – Defines clear boundaries for agent actions by intercepting AgentCore Gateway tool calls before they run using policies with fine-grained permissions.
• AgentCore Evaluations (Preview) – Monitors the quality of your agents based on real-world behavior using built-in evaluators for dimensions such as correctness and helpfulness, plus custom evaluators for business-specific requirements.

We’re also introducing features that expand what agents can do:

• Episodic functionality in AgentCore Memory – A new long-term strategy that helps agents learn from experiences and adapt solutions across similar situations for improved consistency and performance in similar future tasks.
• Bidirectional streaming in AgentCore Runtime – Deploys voice agents where both users and agents can speak simultaneously following a natural conversation flow.

Policy in AgentCore for precise agent control

Policy gives you control over the actions agents can take and are applied outside of the agent’s reasoning loop, treating agents as autonomous actors whose decisions require verification before reaching tools, systems, or data. It integrates with AgentCore Gateway to intercept tool calls as they happen, processing requests while maintaining operational speed, so workflows remain fast and responsive.

You can create policies using natural language or directly use Cedar—an open source policy language for fine-grained permissions—simplifying the process to set up, understand, and audit rules without writing custom code. This approach makes policy creation accessible to development, security, and compliance teams who can create, understand, and audit rules without specialized coding knowledge.

The policies operate independently of how the agent was built or which model it uses. You can define which tools and data agents can access—whether they are APIs, AWS Lambda functions, Model Context Protocol (MCP) servers, or third-party services—what actions they can perform, and under what conditions.

Teams can define clear policies once and apply them consistently across their organization. With policies in place, developers gain the freedom to create innovative agentic experiences, and organizations can deploy their agents to act autonomously while knowing they’ll stay within defined boundaries and compliance requirements.

Using Policy in AgentCore

You can start by creating a policy engine in the new Policy section of the AgentCore console and associate it with one or more AgentCore gateways.

A policy engine is a collection of policies that are evaluated at the gateway endpoint. When associating a gateway with a policy engine, you can choose whether to enforce the result of the policy—effectively permitting or denying access to a tool call—or to only emit logs. Using logs helps you test and validate a policy before enabling it in production.

Then, you can define the policies to apply to have granular control over access to the tools offered by the associated AgentCore gateways.

To create a policy, you can start with a natural language description (that should include information of the authentication claims to use) or directly edit Cedar code.

Natural language-based policy authoring provides a more accessible way for you to create fine-grained policies. Instead of writing formal policy code, you can describe rules in plain English. The system interprets your intent, generates candidate policies, validates them against the tool schema, and uses automated reasoning to check safety conditions—identifying prompts that are overly permissive, overly restrictive, or contain conditions that can never be satisfied.

Unlike generic large language model (LLM) translations, this feature understands the structure of your tools and generates policies that are both syntactically correct and semantically aligned with your intent, while flagging rules that cannot be enforced. It is also available as a Model Context Protocol (MCP) server, so you can author and validate policies directly in your preferred AI-assisted coding environment as part of your normal development workflow. This approach reduces onboarding time and helps you write high-quality authorization rules without needing Cedar expertise.

The following sample policy uses information from the OAuth claims in the JWT token used to authenticate to an AgentCore gateway (for the role) and the arguments passed to the tool call (context.input) to validate access to the tool processing a refund. Only an authenticated user with the refund-agent role can access the tool but for amounts (context.input.amount) lower than $200 USD.

permit(
  principal is AgentCore::OAuthUser,
  action == AgentCore::Action::"RefundTool__process_refund",
  resource == AgentCore::Gateway::"<GATEWAY_ARN>"
)
when {
  principal.hasTag("role") &&
  principal.getTag("role") == "refund-agent" &&
  context.input.amount < 200
};

AgentCore Evaluations for continuous, real-time quality intelligence

AgentCore Evaluations is a fully managed service that helps you continuously monitor and analyze agent performance based on real-world behavior. With AgentCore Evaluations, you can use built-in evaluators for common quality dimensions such as correctness, helpfulness, tool selection accuracy, safety, goal success rate, and context relevance. You can also create custom model-based scoring systems configured with your choice of prompt and model for business-tailored scoring while the service samples live agent interactions and scores them continuously.

All results from AgentCore Evaluations are visualized in Amazon CloudWatch alongside AgentCore Observability insights, providing one place for unified monitoring. You can also set up alerts and alarms on the evaluation scores to proactively monitor agent quality and respond when metrics fall outside acceptable thresholds.

You can use AgentCore Evaluations during the testing phase where you can check an agent against the baseline before deployment to stop faulty versions from reaching users, and in production for continuous improvement of your agents. When quality metrics drop below defined thresholds—such as a customer service agent satisfaction declining or politeness scores dropping by more than 10 percent over an 8-hour period—the system triggers immediate alerts, helping to detect and address quality issues faster.

Using AgentCore Evaluations

You can create an online evaluation in the new Evaluations section of the AgentCore console. You can use as data source an AgentCore agent endpoint or a CloudWatch log group used by an external agent. For example, I use here the same sample customer support agent I shared when we introduced AgentCore in preview.

Then, you can select the evaluators to use, including custom evaluators that you can define starting from the existing templates or build from scratch.

For example, for a customer support agent, you can select metrics such as:

• Correctness – Evaluates whether the information in the agent’s response is factually accurate
• Faithfulness – Evaluates whether information in the response is supported by provided context/sources
• Helpfulness – Evaluates from user’s perspective how useful and valuable the agent’s response is
• Harmfulness – Evaluates whether the response contains harmful content
• Stereotyping – Detects content that makes generalizations about individuals or groups

The evaluators for tool selection and tool parameter accuracy can help you understand if an agent is choosing the right tool for a task and extracting the correct parameters from the user queries.

To complete the creation of the evaluation, you can choose the sampling rate and optional filters. For permissions, you can create a new AWS Identity and Access Management (IAM) service role or pass an existing one.

The results are published, as they are evaluated, on Amazon CloudWatch in the AgentCore Observability dashboard. You can choose any of the bar chart sections to see the corresponding traces and gain deeper insight into the requests and responses behind that specific evaluation.

Because the results are in CloudWatch, you can use all of its feature to create, for example, alarms and automations.

Creating custom evaluators in AgentCore Evaluations

Custom evaluators allow you to define business-specific quality metrics tailored to your agent’s unique requirements. To create a custom evaluator, you provide the model to use as a judge, including inference parameters such as temperature and max output tokens, and a tailored prompt with the judging instructions. You can start from the prompt used by one of the built-in evaluators or enter a new one.

Then, you define the scale to produce in output. It can be either numeric values or custom text labels that you define. Finally, you configure whether the evaluation is computed by the model on single traces, full sessions, or for each tool call.

AgentCore Memory episodic functionality for experience-based learning

AgentCore Memory, a fully managed service that gives AI agents the ability to remember past interactions, now includes a new long-term memory strategy that gives agents the ability to learn from past experiences and apply those lessons to provide more helpful assistance in future interactions.

Consider booking travel with an agent: over time, the agent learns from your booking patterns—such as the fact that you often need to move flights to later times when traveling for work due to client meetings. When you start your next booking involving client meetings, the agent proactively suggests flexible return options based on these learned patterns. Just like an experienced assistant who learns your specific travel habits, agents with episodic memory can now recognize and adapt to your individual needs.

When you enable the new episodic functionality, AgentCore Memory captures structured episodes that record the context, reasoning process, actions taken, and outcomes of agent interactions, while a reflection agent analyzes these episodes to extract broader insights and patterns. When facing similar tasks, agents can retrieve these learnings to improve decision-making consistency and reduce processing time. This reduces the need for custom instructions by including in the agent context only the specific learnings an agent needs to complete a task instead of a long list of all possible suggestions.

AgentCore Runtime bidirectional streaming for more natural conversations

With AgentCore Runtime, you can deploy agentic applications with few lines of code. To simplify deploying conversational experiences that feel natural and responsive, AgentCore Runtime now supports bidirectional streaming. This capability enables voice agents to listen and adapt while users speak, so that people can interrupt agents mid-response and have the agent immediately adjust to the new context—without waiting for the agent to finish its current output. Rather than traditional turn-based interaction where users must wait for complete responses, bidirectional streaming creates flowing, natural conversations where agents dynamically change their response based on what the user is saying.

Building these conversational experiences from the ground up requires significant engineering effort to handle the complex flow of simultaneous communication. Bidirectional streaming simplifies this by managing the infrastructure needed for agents to process input while generating output, handling interruptions gracefully, and maintaining context throughout dynamic conversation shifts. You can now deploy agents that naturally adapt to the fluid nature of human conversation—supporting mid-thought interruptions, context switches, and clarifications without losing the thread of the interaction.
