About the AI model
- Models
- A short curated list of open WebLLM builds (Llama, Gemma, Qwen, Phi, DeepSeek). You pick one in the tool.
- Runtime
- WebLLM in a Web Worker, on your GPU via WebGPU. There is no server-side model.
- Download
- 1–5 GB depending on the model, downloaded once, fetched from Hugging Face and MLC the first time you load a model and then cached by your browser
- Your chat
- Stays in this tab. Prompts and replies are never part of any network request.
Prompts and replies stay in this tab. The only network traffic is the page, the WebLLM runtime, and the one-time model download from Hugging Face and MLC. We never see your chat.
To be precise: your browser still downloads this page, its scripts and the model weightsover the network, and our web server keeps standard access logs. What never travels is the content you put into a local tool.
