📄 Description

Summary

fix: model listing for GitHub Models in OpenAI-compatible connections.

Open WebUI currently requests <base_url>/models for provider model refresh. For GitHub Models, this fails when base URL is https://models.github.ai/inference, because model catalog is exposed at https://models.github.ai/catalog/models.

This PR adds provider-aware endpoint resolution for model listing while preserving existing behavior for other providers.

Changes

  • Added get_models_endpoint(url: str) helper in backend/open_webui/routers/openai.py
  • If URL contains models.github.ai, model list endpoint is mapped to https://models.github.ai/catalog/models
  • Replaced hardcoded f"{url}/models" calls with get_models_endpoint(url) in:
    • get_all_models_responses
    • get_models
    • verify_connection

Why

Without this mapping, model refresh fails with 404/content-type parsing errors against .../inference/models.

Validation

  • Syntax check:
    • python3 -m py_compile backend/open_webui/routers/openai.py
  • Manual validation:
    • Reproduced network error in Open WebUI with GitHub Models base URL
    • Confirmed requests were sent to /inference/models before fix
    • Verified model listing works when mapped to /catalog/models
