HTTP server providing OpenAI API compatibility for LLM Gateway.
- OpenAI client SDK drop-in replacement (baseURL only change)
- POST /v1/chat/completions endpoint with streaming support
- GET /v1/models for client library discovery
- Automatic model mapping: gpt-4 → qwen2.5:32b, etc.
- Server-Sent Events (SSE) streaming implementation
- Full TypeScript types and comprehensive test suite
- Graceful shutdown handling (SIGTERM/SIGINT)
- Health check endpoint with gateway status
- Performance: Same as gateway (100-500ms with fallback to Ollama)
