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. 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.

Codex is the OpenAI coding agent for AI-powered software development. With GPT models powering inference, Codex introduces a new class of intelligence optimized for complex, long-horizon developer workflows. You can use the ChatGPT desktop app, the Codex CLI, and IDE integrations with Visual Studio Code, JetBrains, and Xcode. Model inference is routed through the Responses API on Amazon Bedrock.

For customers with data residency requirements, processing stays within the Amazon Bedrock AWS Region that you select. You pay per token with no seat licenses and no per-developer commitments. 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. This helps you protect sensitive information and meet stringent data-governance, privacy, and security requirements.
