Paris-based lab Mistral announced its first family of AI reasoning models, called Magistral, fine-tuned for multi-step logic, improved interpretability, and a traceable thought process, unlike general-purpose models.
It follows the release of OpenAI’s o3 and Google’s Gemini 2.5 Pro.
Magistral works through problems requiring step-by-step deliberation and analysis for improved consistency and reliability. In this regard, it mimics human thinking through logic, insight, uncertainty, and discovery.
Magistral comes in two variants, both suited for a wide range of enterprise use cases, from structured calculations and programmatic logic to decision trees and rule-based systems.
• Magistral Small, a 24 billion parameter open-source version, available for download from the AI dev platform Hugging Face under the Apache 2.0 license.
• Magistral Medium, a more powerful, enterprise-grade version, is in preview on Mistral’s Le Chat chatbot platform and the company’s API, as well as third-party partner clouds.
Purpose-built for transparent reasoning.
The release of Magistral follows the debut of Mistral’s “vibe coding” client, Mistral Code.
Founded in 2023, Mistral builds AI-powered services, including Le Chat and mobile apps. It’s backed by venture investors like General Catalyst. It has raised over $1.24 billion to date.
