Verify Feature Scope
I have read through and understood the scope definition for feature requests in the Issues section. I believe my feature request meets the definition and belongs in the Issues section instead of the Discussions.
Problem Description
It would be nice to have support for the anthropic endpoints /v1/messages
so we can use claude code with models on open webui.
Desired Solution you'd like
Support anthropic format (/v1/messages)

use pipes, their openai compatible api, openrouter, litellm or other services instead
