# Web Search on Amazon Bedrock is now available in AWS GovCloud (US-West)

**[AWS](https://daily.dev/sources/aws)** · 2 min read · 0 upvotes · 0 comments

## Summary

AWS has expanded availability of its Web Search built-in tool for Amazon Bedrock to AWS GovCloud (US-West), letting compliance-sensitive government and public-sector workloads ground OpenAI GPT model responses with live web results and citations. The tool keeps request data within the AWS boundary by default, is governed via IAM for account/org-level and Region-level control, and is added by including a web_search tool type in OpenAI Responses API requests. At launch in GovCloud it supports GPT-5.4, GPT-5.6 Terra, and Luna models, joining existing availability in US East (N. Virginia), US East (Ohio), and US West (Oregon).

_Teams building compliant AI grounding pipelines can track Bedrock regional rollouts like this on daily.dev._

### Which models support Web Search on Amazon Bedrock in AWS GovCloud (US-West)?

At launch, Web Search in AWS GovCloud (US-West) supports GPT-5.4, GPT-5.6 Terra, and Luna models. These are the OpenAI models available through Amazon Bedrock's OpenAI Responses API that can use the web_search tool type to ground answers in current web information.

_Developers choosing grounded models for government workloads follow updates like this on daily.dev._

### How do I add web search to an OpenAI Responses API request on Amazon Bedrock?

Add a tool of type web_search to the tools array in the OpenAI Responses API request using an existing OpenAI client library along with an Amazon Bedrock API key. The model invokes the tool only when it determines the request needs current information, and no search index, crawler, or tool-call loop needs to be self-hosted.

_Developers wiring up grounded model calls track implementation details like this on daily.dev._
