Mistral, a French AI lab, announced on Tuesday the release of Magistral, a family of reasoning models designed to work through problems step-by-step, enhancing consistency and reliability across varied subjects.
Magistral is available in two versions: Small and Medium. Magistral Small, a 24 billion parameter model, can be downloaded from Hugging Face under the Apache 2.0 license. Magistral Medium is accessible in preview on Mistral’s Le Chat chatbot platform, the company’s API, and partner clouds.
According to Mistral’s blog post, Magistral is suited for uses ranging from calculations and logic to decision trees and rule-based systems. The company adds that the models are fine-tuned for multi-step logic, thereby improving interpretability and providing a traceable thought process in the user’s language.
Mistral, founded in 2023, develops AI-powered services, including Le Chat and mobile apps. The company is backed by venture investors such as General Catalyst and has raised over €1.1 billion (approximately $1.24 billion) to date.
According to Mistral’s benchmarks, Magistral Medium underperforms compared to Google’s Gemini 2.5 Pro and Anthropic’s Claude Opus 4 on GPQA Diamond and AIME, tests measuring physics, math, and science skills. Magistral Medium also trails Gemini 2.5 Pro on LiveCodeBench, a programming benchmark.
Mistral states in its blog post that Magistral delivers answers at “10x” the speed of competitors in Le Chat. The company also notes that the model supports multiple languages, including Italian, Arabic, Russian, and Simplified Chinese.
Concerning the uses of Magistral, Mistral writes that it is designed for research, strategic planning, operational optimization, and data-driven decision-making. The company continues, stating it is capable of executing risk assessment and modeling along with calculating delivery windows under constraints.
The Magistral release follows the debut of Mistral Code, a “vibe coding” client. Previously, Mistral introduced coding-focused models and Le Chat Enterprise, a corporate chatbot service that offers an AI agent builder and integrates Mistral’s models with services such as Gmail and SharePoint.
