Summary

  • Add POST /api/chat/guest endpoint (no auth required)
  • Add proxyGuestChat() method using configurable LLM endpoint
  • Add streamGuestChat() function to frontend chat API
  • Modify useChat to fall back to guest mode on auth errors (403/401)
  • Remove !user check from ChatInput disabled prop

Configuration

Guest LLM configured via env vars:

  • GUEST_LLM_URL - OpenAI-compatible endpoint (default: http://10.1.1.42:11434/v1)
  • GUEST_LLM_API_KEY - API key (optional)
  • GUEST_LLM_MODEL - Model name (default: llama3.2)

Testing

  1. Open Mosaic Stack without logging in
  2. Click chat button
  3. Send a message - should use guest endpoint
  4. Verify streaming response works

Fixes chat overlay 403 error for unauthenticated users.
