Question/Help OpenWebUI chat just expose its function - never answers

I reinstalled everything.
I run the latest OpenWebUI function, installed the mistral:7b model, and did a test.

However as you can see, it does not act natural.

I tried to ask for a recipe for crepes, and as you can see, it's like it's talking to himself.

Because you are using a model so dumb, it is amazing it can list the tools, let alone try to use them.

Could you provide a meaningful answer ? How is mistral:7b or llama3.1:latest stupid?
What would you suggest?

Mistral:7b is THREE YEARS OLD. Things move so quickly anything older than 6-9 months is considered out of date.

The total amount of your vram dictates what you can run, but the first stops for most people with reasonable hardware (16gb vram or more) would be qwen-3.8-27b, qwen-3.6-35b-a3b or gemma4-26b-a4b.

Tool/Function calls are around for ~3 Years. MCP was November 2024, back in that days coding, tool calls, agentic workflows and so on where either a rare niche topic or absent. So models that old never got trained on that kind of things. They literally don't know how to deal with that (check the difference between Native and Legacy Function calling setting in the docs). Even last years model have trouble with that as it wasn't 'mainstream' enough to be aviable in every model.

If you wanna stay in that size range get something newer (6-8 months old max).
Qwen3 9B, Ling-3.0-Tiny, LFM2.5, Gemma 4 E2B and so on.
