Amazon Bedrock Web Search Tool Now Available in AWS GovCloud (US-West)

The Web Search built-in server-side tool on Amazon Bedrock is now available in AWS GovCloud (US-West), providing grounded web results for compliance-sensitive government and public-sector workloads. This tool helps supported OpenAI GPT models ground responses with information from the web, including citations to sources used.

What to do

• Add a tool of type web_search to the tools array in your OpenAI Responses API request using your existing OpenAI client library with an Amazon Bedrock API key.
• Ensure the model uses the tool when it determines a request needs current information.

At launch, Web Search in AWS GovCloud (US-West) supports GPT-5.4, GPT-5.6 Terra, and Luna models.
