Summary

Currently, openai-compatibility only supports the OpenAI Chat Completions wire format. Users who want to add a third-party Claude or Gemini proxy have no way to do so — the Claude/Gemini sections only accept official API keys with hardcoded endpoints.

Proposal

Rename / extend openai-compatibility into a Custom Provider type that lets users specify the wire format via a dropdown:

Wire Format Protocol Example Use Case
chat-completions OpenAI /v1/chat/completions Third-party OpenAI proxies
responses OpenAI /v1/responses Codex-style providers
claude Anthropic /v1/messages Third-party Claude proxies
gemini Google /v1beta/models/*/generateContent Third-party Gemini proxies

How it would work

Config (YAML)

custom-providers:   # or keep openai-compatibility with a new field
  - name: my-claude-proxy
    base-url: https://claude-proxy.example.com
    wire-api: claude          # <-- new field
    api-key-entries:
      - api-key: sk-xxx
    models:
      - name: claude-sonnet-4-5-20250514

Frontend

  • Edit page adds a Wire Format dropdown (4 options above)
  • Model discovery adapts per format (OpenAI /v1/models, Claude /v1/models with anthropic-version, Gemini /v1beta/models, etc.)

Backend

  • The backend already has full conversion logic for all four formats (used by the existing Claude/Gemini/OpenAI handlers)
  • Just needs to read the wire-api field from each custom provider entry and route to the corresponding existing handler
  • Minimal new code required since all protocol handling already exists

Benefits

  • Users can add any third-party provider regardless of API format
  • No need to wait for official provider support
  • Reuses existing backend logic — low implementation cost
