OpenAI-compatible

Same paths, same JSON, same SSE frames as OpenAI — existing SDKs and editors work unchanged.

Streaming by default

Read tokens as they are generated; end the stream with the standard [DONE] sentinel.

Tool calling & JSON

Function calling, structured output and multi-turn tool loops for agentic workflows.

Fair-use limits

Per-key rate limits and monthly caps keep the shared fleet responsive at peak load.

Other models on the same key

Switch per request — no new integration.
