# Darwin-9B-NEG — API Chat Demo

A lightweight chat demo for **Darwin-9B-NEG**, served over an OpenAI-compatible
API (no local GPU). The UI is identical to the Darwin-9B-Opus space; only the
backend is API-based.

- **Model**: [FINAL-Bench/Darwin-9B-NEG](https://huggingface.co/FINAL-Bench/Darwin-9B-NEG)
- **GPQA Diamond**: #22 globally (84.34)
- **Serving**: OpenAI-compatible streaming API
- Introduced in [Darwin Family](https://arxiv.org/abs/2605.14386).

Optional Space secrets: `VIDRAFT_API_BASE`, `VIDRAFT_API_MODEL`,
`VIDRAFT_API_KEY`, `OAUTH_CLIENT_ID`, `OAUTH_CLIENT_SECRET`, `BRAVE_API_KEY`.
