Does UI-Tars support Claude model via AWS bedrock?
Is there any way to achieve it. Any help will be appreciated.

I don’t think UI-TARS has official/native AWS Bedrock support yet, but it should still be possible to use Claude through Bedrock depending on how the provider layer is implemented.

Since UI-TARS works around configurable LLM providers, the main idea would be routing Anthropic requests through AWS Bedrock instead of the direct Anthropic API.

Claude already supports Bedrock officially using configs like:

CLAUDE_CODE_USE_BEDROCK=1
AWS_REGION=us-east-1

and Bedrock Claude inference profiles.

So if UI-TARS supports:

• custom endpoints,
• LiteLLM,
• Anthropic-compatible APIs,
• or env-based provider configs,

then it should work with Bedrock without major issues.

The only thing that could block it is if the app hardcodes Anthropic’s direct API endpoints internally. In that case, a small provider layer change may be needed.
