  1. ChatGPT desktop app now available via Bedrock in AWS GovCloud

    The ChatGPT desktop app is now available on Amazon Bedrock in AWS GovCloud (US), according to the supplied report. It provides Work for complex, multi-step tasks and Codex for software development, testing and code review. The described setup routes inference through the Responses API and Amazon Bedrock Mantle in us-gov-west-1, with access governed by AWS IAM and existing GovCloud network controls. The report also says processing can remain within the selected Bedrock region, billing is per token without seat licenses or per-developer commitments, and a configurable zero-data-retention mode prevents prompts and responses from being written to durable storage by AWS or shared with model providers. Organizations remain responsible for reviewing and authorizing their workloads.

  2. AWS Explores Prompt Caching Patterns for AI Agents on Bedrock

    The AWS Machine Learning Blog explains how Amazon Bedrock prompt caching can reuse previously processed context, including instructions, tool definitions, and conversation history, instead of resending the full context on every agent step. The guide covers implicit and explicit cache breakpoints, stable prefixes, additional tools, cache eligibility, and write costs. In one six-turn workload, AWS reported about 62% lower input cost with implicit caching and about 61% with explicit rolling breakpoints on GPT-6 Astra, while cautioning that results vary by workflow.

  3. Amazon Bedrock adds structured outputs for Claude models

    Amazon Bedrock now supports structured outputs for all available Anthropic Claude models through its bedrock-runtime and bedrock-mantle endpoints. The feature uses constrained decoding to enforce JSON schemas during generation and adds strict schema validation for tool parameters, reducing custom parsing and retry logic for production workflows.
