# VibeThinker-3B ZeroGPU Chat

This Space hosts `WeiboAI/VibeThinker-3B` on Hugging Face ZeroGPU.

The frontend is the upstream `huggingface/chat-ui` SvelteKit app vendored in `chat-ui/` at commit `e1b4806068a0312752d9ee0acc48bb8d9ae24b71`.

`app.py` runs Gradio Server mode for the ZeroGPU-backed model API, exposes local OpenAI-compatible `/v1/models` and `/v1/chat/completions` routes, starts chat-ui on an internal Node server, and reverse-proxies browser traffic to chat-ui.
