Mistral的首个强推理模型：拥抱开源，推理速度快10倍

Core Viewpoint - Mistral AI has launched a new series of large language models (LLMs) named Magistral, showcasing strong reasoning capabilities and the ability to tackle complex tasks [4]. Group 1: Model Overview - The launch includes two versions: a proprietary model for enterprise clients called Magistral Medium and an open-source version with 24 billion parameters named Magistral Small [5]. - The open-source version is available under the Apache 2.0 license, allowing for free use and commercialization [5]. Group 2: Performance Metrics - In benchmark tests, Magistral Medium scored 73.6% on AIME2024, with a majority vote score of 64% and a score of 90% [6]. - Magistral Small achieved scores of 70.7% and 83.3% in the same tests [6]. - The model also excelled in high-demand tests such as GPQA Diamond and LiveCodeBench [7]. Group 3: Technical Features - Magistral Medium demonstrates programming capabilities, generating code to simulate gravity and friction [10]. - The model maintains high-fidelity reasoning across multiple languages, including English, French, Spanish, German, Italian, Arabic, Russian, and Chinese [11]. - With Flash Answers in Le Chat, Magistral Medium can achieve up to 10 times the token throughput compared to most competitors, enabling large-scale real-time reasoning and user feedback [14]. Group 4: Learning Methodology - Mistral employs a proprietary scalable reinforcement learning pipeline, relying on its own models and infrastructure rather than existing implementations [15]. - The model's design principle focuses on reasoning in the same language as the user, minimizing code-switching and enhancing performance in reasoning tasks [16][17]. Group 5: Market Positioning - Magistral Medium is being integrated into major cloud platforms, including Amazon SageMaker, with plans for Azure AI, IBM WatsonX, and Google Cloud Marketplace [20]. - The pricing for input tokens is set at $2 per million and $5 per million for output tokens, significantly higher than the previous Mistral Medium 3 model, which was $0.4 and $2 respectively [21]. - Despite the price increase, Magistral Medium's pricing strategy remains competitive compared to external competitors, being cheaper than OpenAI's latest models and on par with Gemini 2.5 Pro [22].
