Amazon Bedrock
Amazon Bedrock is a fully managed generative AI service platform provided by Amazon Web Services (AWS), allowing enterprises to access foundation large language models from multiple leading AI vendors through a unified API. Built on a serverless architecture, the platform supports enterprise-grade capabilities including model fine-tuning, retrieval-augmented generation (RAG), and agent construction, enabling developers to build and deploy AI applications without managing underlying infrastructure.
Core Facts
Vercel AI SDK encapsulates the communication logic with mainstream large model APIs such as OpenAI, Anthropic, and Google, and provides React Hooks such as useChat and useCompletion.
Amazon Bedrock is a fully managed foundation model service platform launched by AWS in 2023, integrating models from multiple AI vendors including Anthropic, Meta, Mistral, and Cohere.
AWS Bedrock is a managed AI foundation model service launched by Amazon Web Services that allows enterprises to call multiple large models, including Claude, through AWS.
Timeline (last 90 days)
Using Claude Haiku 4.5 on Amazon Bedrock, after the fix the cache reads for messages 2 and 3 were both 18,767 tokens, with cache writes of 597 and 620 tokens respectively.
Fast Mode currently does not support Amazon Bedrock, the Claude Platform on AWS, Google Cloud, the Batch API, or Priority Tier committed usage.
Chunking defaults vary widely across tools: LangChain's basic text splitter defaults to 4000 characters with 200 overlap; LlamaIndex's constant file uses 1024 tokens with 20 overlap; Amazon Bedrock defaults to about 300 tokens; OpenAI's automatic vector store strategy uses 800 tokens with 400 overlap.
Claude Opus 5.5's ecosystem includes Claude Code, Agent SDK, Managed Agents, and it can be used on Amazon Bedrock, Google Cloud, and Microsoft Foundry, supporting long tasks running up to 18 hours.
Claude Opus 5.5's ecosystem includes Claude Code, Agent SDK, Managed Agents, availability on Bedrock/Google Cloud/Microsoft Foundry, plus a year's accumulation of third-party integrations.
Opus 5.5 and Sonnet 5.5 do not support structured outputs (including strict mode) on Amazon Bedrock, and can only send tool_choice as auto.
Computer use tools must be declared as the computer_toolset_20260801 toolset and no longer require a beta header; Sonnet 5.5 rejects computer_20250124 on all platforms, with Amazon Bedrock as an exception retaining computer_20251124.
What Amazon Bedrock AgentCore provides is not an out-of-the-box IDP product, but a set of infrastructure for building self-evolving document processing Agents.
Tamnoon built a cloud remediation orchestrator called Tami on Amazon Bedrock, letting AI autonomously investigate and safely remediate cloud security findings.
Tamnoon's reasons for choosing Amazon Bedrock include: providing unified access to multiple foundation models so models can be selected per task, managed features that remove the need to build inference infrastructure, and deep integration with AWS-native services.
