French artificial intelligence laboratory Mistral has officially launched its first series of reasoning models — Magistral, marking another significant advancement in the field of AI. This series includes two versions: Magistral Small and Magistral Medium, aimed at enhancing logical reasoning capabilities in fields such as mathematics and physics. These models solve problems step by step, bearing some resemblance to other reasoning models like OpenAI's o3 model and Google's Gemini2.5Pro.
Magistral Small boasts 24 billion parameters and is already available for download on the AI development platform Hugging Face under the Apache2.0 license, making it convenient for developers. Magistral Medium, a more powerful version, is currently in preview mode and can be experienced through Mistral's Le Chat chat platform, company APIs, and third-party partner cloud services.
In its official blog post, Mistral noted that Magistral is suitable for various enterprise-level applications, including structured calculations, program logic, and rule-based systems. By fine-tuning multi-step logic, Magistral can enhance explainability and provide users with traceable thought processes, which is particularly important for many industries requiring high transparency.
Despite having certain financial and technical strengths, Mistral has lagged behind some top-tier laboratories in the development of reasoning models in recent years. According to its own benchmarks, Magistral performed worse than Gemini2.5Pro and Claude Opus4 in the GPQA Diamond and AIME tests evaluating physics, mathematics, and scientific abilities. In the LiveCodeBench programming benchmark test, Magistral Medium also failed to surpass Gemini2.5Pro's performance.
Nevertheless, Mistral emphasized Magistral's unique advantages. The model's answer speed on the Le Chat platform is ten times faster than competitors and supports multiple languages including Italian, Arabic, Russian, and Simplified Chinese. Additionally, Mistral stated that Magistral is designed for research, strategic planning, operational optimization, and data-driven decision-making, excelling in multi-factor risk assessment and modeling.
The launch of Magistral also coincides with the release of Mistral's "atmosphere programming" client, Mistral Code, showcasing the company's further expansion into the programming and enterprise service sectors.
