Background

Mistral just released Mistral Medium 3.5. See https://docs.mistral.ai/models/model-cards/mistral-medium-3-5-26-04

Summary

Adds mistral-medium-3.5 to the modelid type, and adds it to the list of models that supports reasoning effort.
Adds the model to documentation.

Manual Verification

I tried a modified version of the Mistral text and stream examples (with the model id swapped out for mistral-medium-3.5). I also tried the reasoning effort example with the model id swapped out. Both work as expected.

Checklist

  • All commits are signed (PRs with unsigned commits cannot be merged)
  • Tests have been added / updated (for bug fixes / features)
  • Documentation has been added / updated (for bug fixes / features)
  • A patch changeset for relevant packages has been added (for bug fixes / features - run pnpm changeset in the project root)
  • I have reviewed this pull request (self-review)

Future Work

I left the image support crossed out, since this is also the case for e.g. mistral-small-latest, and I haven't tested this. Maybe both should be updated when tested.

Could you also add mistral-medium-3 as an alias?

Done! Felt like minor to me because it's a backwards compatible feature, but that's very subjective :)

Please do not use minor or major changesets, we'll let you know when you need to use a different changeset type than patch.

Aha, should've read the docs, thanks for linking!
