How to I change the API Host from https://localhost:11434 to something else, such as https://api.example.com or just /api on the same server?

What other environment variables can I set before running npm run build?

Hi,

Currently, our web UI supports the OLLAMA_ENDPOINT variable in the format: OLLAMA_ENDPOINT="http://[insert your ollama URL]", where you must include the port number as well. For instance: OLLAMA_ENDPOINT="http://192.168.4.1:11434/".

If you have any further questions or need assistance, please don't hesitate to ask.

I had running with the ENVs like this, but it didn't work.

SERVER_ENDPOINT='http://localhost:11434' npm run dev

I think that's because I chose SERVER_ENDPOINT, which was only hardcoded.

Do you know how to change the build step to make use of ENVs? It can't be through process.env.* since that doesn't exist at build time... unless it does?

Maybe PageServerLoad can use process.env.* during the build phase?

Maybe `PageServerLoad` _can_ use `process.env.*` during the build phase?

With the latest Pull Request #10 commit, you can use the following command:

OLLAMA_API_ENDPOINT='http://localhost:11434' npm run dev

Let me know if you need further assistance.

Phase 2 Update: Local Qwen Model + Async Fixes

Changes (commit 0b731a7e2)

  • Model switch: Default bot model changed from OpenAI.gpt-4o-mini to Local.qwen3.5-35b-a3b-fast (local Qwen 3.5 35B)

    • Free inference (electricity only) vs. paid API
    • Better quality for French responses
    • ~26s response time on local vLLM (3x RTX 4090)

  • Async timeout fixes:

    • aiohttp.ClientTimeout(total=300, sock_read=180) — local models need longer for initial response
    • Message processing moved to asyncio.create_task — prevents Socket.IO event loop blocking
    • Typing indicator made fire-and-forget to avoid potential deadlocks

  • Model visibility fix (all 7 tenants):

    • Set base_model_id on expert-analyste, redacteur-technique, vision-expert, Local.qwen3.5-35b-a3b-fast
    • These custom models are now visible to all non-admin users (was broken because base_model_id=None)

  • Upstream sync: Merged v0.8.8 from upstream (504 commits, including Open Terminal fixes)

Verified

✓ FAQ bot responds using Local.qwen3.5-35b-a3b-fast (26-35s response time)
✓ Replies posted as thread replies in channels
✓ <think> tags stripped from model output
✓ Typing indicator sent without blocking
✓ Bot reconnects automatically after disconnection
✓ Model visible to bot user (26 models total)

Remaining for Phase 3

  • Multi-tenant deployment (bot per tenant or multi-connection)
  • RAG integration with knowledge bases
  • Production monitoring
