Configure the ChatGPT desktop app with Amazon Bedrock in AWS GovCloud (US)

This article provides a technical walkthrough for configuring the ChatGPT desktop app with Amazon Bedrock in AWS GovCloud (US), enabling secure model inference for government organizations with strict data residency and security requirements.

• ChatGPT desktop app now available on Amazon Bedrock in AWS GovCloud (US) with Work and Codex components
• Model inference routed through Amazon Bedrock Mantle in us-gov-west-1 with IAM and network controls
• Zero data retention (ZDR) supported; prompts and responses not written to durable storage or shared with providers
• Configuration uses API-mode sign-in, managed device policy, named AWS profile, and network restrictions
• Three-step setup: authenticate with AWS GovCloud credentials, configure config.toml and requirements.toml files, launch and verify deployment
• Authentication supports Amazon Bedrock API keys or AWS SDK credential chain including AWS SSO
• requirements.toml enforces security limits; config.toml specifies model provider and operational settings
• Network restrictions allow only bedrock-mantle.us-gov-west-1.api.aws endpoint; all OpenAI external connections denied

Organizations can deploy ChatGPT desktop app with controlled security policies, validated AWS identities, and verified network controls to meet government compliance and data governance requirements.
