KEY TAKEAWAYS
  • • The ChatGPT desktop app is available on Amazon Bedrock in AWS GovCloud (US).
  • • It provides access to OpenAI's frontier models through Work and Codex components.
  • • Model requests are routed through Amazon Bedrock Mantle in us-gov-west-1.
  • • Zero data retention is supported so prompts and responses are not written to durable storage.

Solution Overview

The ChatGPT desktop app is now available on Amazon Bedrock in AWS GovCloud (US), providing access to OpenAI’s frontier models through two components. Work completes complex, multi-step tasks and delivers review-ready results, and Codex is a coding agent for developing, testing, and reviewing software. This walkthrough is intended for organizations whose security architecture requires model inference to use AWS GovCloud (US) identities, endpoints, and Regional controls.

Security and Controls

It configures Codex to route model requests through Amazon Bedrock Mantle in us-gov-west-1, where access can be governed using AWS Identity and Access Management (IAM) and existing AWS GovCloud (US) network controls. Zero data retention (ZDR) is also supported. In this configurable mode, prompts and responses are processed without being written to durable storage by AWS or shared with model providers.
