Kimi Coder

Watch Kimi K3 code a web page live at ~460 tokens/second, served by Modal.

Describe a page, watch the HTML stream in on the left and render live on the right. Each follow-up message extends the spec and regenerates the whole page — at this speed a full regeneration feels like an edit.

How it works

  • index.ts — Hono server: serves the frontend and streams /api/generate as server-sent events
  • kimi.ts — one streaming chat completion against Modal's OpenAI-compatible Kimi K3 endpoint, with reasoning disabled (chat_template_kwargs: { thinking: false }) since the demo is about raw codegen speed
  • frontend/ — React chat + code stream + live preview, with measured tok/s per generation

Remix it

  1. Remix this val
  2. Create a Kimi K3 endpoint at modal.com and a proxy-auth token, then set the endpoint URL in kimi.ts and:
