Mistral AI Introduces Magistral, French AI innovator Mistral AI has released its first reasoning model under the name Magistral. The debut includes two variants: Magistral Small, a 24‑billion‑parameter open‑source model, and Magistral Medium, a more powerful proprietary version designed for enterprise needs. These are engineered to perform “chain-of-thought” reasoning—breaking down complex queries step-by-step—marking a shift from pure scale to actual understanding.

- New Reasoning-Focused Models: Mistral introduces ‘Magistral Small’ and ‘Magistral Medium’ models, optimized for structured reasoning across logic, math, physics, and enterprise tasks.
- Open-Source Access: Magistral Small is available under the Apache 2.0 license via Hugging Face supporting full modification, commercial use, and developer customization.
- Fast and Multilingual: It offers low-latency inference (up to 10x faster), and handles languages like Arabic, Russian, and Simplified Chinese without English translation layers.
- Benchmark Gaps: While Magistral Medium trails leading models on some reasoning and coding benchmarks, its speed and multilingual support offer competitive advantages.
Magistral Small and Medium
- Magistral Small (24B parameters), available now under the Apache 2.0 open-source license via Hugging Face.
- Magistral Medium, a more powerful version currently accessible via Mistral’s Le Chat chatbot, its developer API, and through selected cloud partners.
Both models are designed to perform multi-step reasoning, with a focus on traceable, consistent responses. These capabilities make them suitable for logic-based tasks, rule processing, decision trees, and structured problem-solving.
This comes right after the release of its new enterprise-grade Document AI platform, which claims to set a new benchmark in speed and accuracy for OCR-based document processing.
Magistral Medium scored 73.6% on the 2024 AIME benchmark and 90% with majority voting at 64-shot prompts. The open Magistral Small model scored 70.7% and 83.3%, respectively. The company mentioned that both models are tuned for legal research, financial modelling, software engineering, and regulated sectors like healthcare and government.
“Magistral is fine-tuned for multi-step logic, improving interpretability and providing a traceable thought process in the user’s language, unlike general-purpose models,” the company wrote in the blog post. It supports reasoning in English, French, Arabic, German, Chinese, and several other languages.
Performance and Limitations
While the models represent a strategic expansion for Mistral, early benchmarks show mixed results.
On reasoning benchmarks like GPQA Diamond and AIME, and programming-focused tests such as LiveCodeBench, Magistral Medium scores below competing models like Gemini 2.5 Pro and Claude Opus 4.
- Faster inference: The model reportedly delivers responses up to 10x faster than comparable models when deployed in Le Chat.
- Multilingual processing: The models natively handle queries in languages such as Arabic, Russian, Italian, and Simplified Chinese, removing the need for English translation and improving latency and contextual accuracy.
How Magistral Fits Into the Competitive AI Landscape
Magistral’s launch positions Mistral AI as a key challenger in the reasoning model space, with a unique dual-source strategy—open‑source weight availability meets enterprise-grade power. It’s a bold response to a growing AI innovation landscape where DeepSeek, OpenAI, Google, and Anthropic push capabilities further.
The Medium version, while reportedly behind top-tier reasoning rivals in benchmarks, brings advantages like high-token throughput—over 1,000 tokens per second—and compliance with corporate standards. This makes it appealing for large-scale document analysis, legal reasoning, and detailed technical queries despite slight performance gaps.
Getting Your Hands on Magistral
Magistral Small is already available via platforms like Hugging Face under an Apache‑2.0 license—ideal for developers and researchers.
The Magistral Medium enterprise model is in private preview, with access typically granted through Mistral’s commercial licensing or cloud partners such as Azure. To use Mag Small, a basic Hugging Face or Mistral API account is sufficient; Medium users should contact Mistral directly or engage through their existing cloud providers.
Final Thoughts
Mistral AI’s Magistral launch represents a pivotal shift in large language model development—from greater size to greater reasoning intelligence. By offering both Magistral Small (open‑source) and Magistral Medium (enterprise-grade), Mistral delivers accessible innovation with strategic flexibility.
Whether for standalone tasks or enterprise deployment, Magistral offers a compelling balance of performance, transparency, and language agility—truly Europe’s first major entry into chain-of-thought AI .
