Configure the ChatGPT desktop app with Amazon Bedrock in AWS GovCloud (US)
aws ·
AWS has enabled the ChatGPT desktop app to connect with Amazon Bedrock in AWS GovCloud (US), allowing organizations to access OpenAI’s frontier models while maintaining strict data residency and security controls. This configuration is designed for entities requiring model inference to utilize specific AWS GovCloud identities, endpoints, and regional restrictions. The setup supports two primary components: Work for complex task planning and Codex for coding assistance, both routing through the Amazon Bedrock Mantle endpoint in us-gov-west-1. Key security features include Zero Data Retention (ZDR), ensuring prompts and responses are not stored durably by AWS or shared with providers. Administrators can enforce strict network policies via TOML configuration files, restricting access solely to the approved Bedrock endpoint while blocking other external connections. Authentication is managed through AWS SDK credential chains or API keys, integrating with existing IAM and SSO infrastructure. This guided walkthrough helps security teams test and document controlled local deployments before approving broader organizational use.
