Today, we’re excited to announce our latest contribution to AI research with Magistral — our first reasoning model. Released in both open and enterprise versions, Magistral is designed to think things through — in ways familiar to us — while bringing expertise across professional domains, transparent reasoning that you can follow and verify, along with deep multilingual flexibility.

We’re releasing the model in two variants: Magistral Small — a 24B parameter open-source version and Magistral Medium — a more powerful, enterprise version.

It seems mistral finally released their own version of a small 3.1 2503 with CoT reasoning pattern embedding. Before this the best CoT finetune of Small was DeepHermes with deepseeks r1 distill patterns. According to the technical report, mistral baked their own reasoning patterns for this one so its not just another deepseek distill finetune.
