Add Devstral support

[matthieuHenocque]

MistralAI just released a new coding assistant with improved tools, but it relies on Open Hands API

It has already been implemented by Continue.dev

EDIT:
This PR has been merged, but it doesn't add tool support of Devstral, even though the tools are listed in Configure Built-in Tools. No tool works.

Hey @matthieuHenocque can you help here specifying how are using it? Like through mistral it does support tool call. Are you using it through ollama or something else?

[matthieuHenocque]

Hey @imumesh18

I'm using Ollama on macOS 15.5 (M2 Max 32GB)

The server is connected. I can chat with the model. I have access to the tools dropdown, where I can choose between Write, Ask and Minimal

Ohk. Yaa with local one I pretty sure it might not work reliably. But you can try by changing the model temperature. set it to something like 0.2 or 0.3 and see if that helps: https://zed.dev/docs/ai/temperature. Other than don't anything else which is possible right now. It might be ollama issue as well. Saw couple of people reporting different experience with ollama and mistral api.

I would like to use the Devstral using the Mistral API key. Of all the LLM providers, Mistral is the only one I can think of that is EU-hosted.

For some reason, on the latest version of Zed, it says "Tools unsupported" for all Mistral Models. I am using my own Mistral API Key. Inline assistant works, however.

@matthieuHenocque new release 0.188.3 . update and try again

There is no more Tools Unsupported message in the window and devstral-small-latest is available.
