OpenEuroLLM vs. Mistral Large 3

OpenEuroLLM embodies a collaborative initiative among leading AI companies and research institutions throughout Europe, focused on developing a series of open-source foundational models to enhance transparency in artificial intelligence across the continent. This project emphasizes accessibility by providing open data, comprehensive documentation, code for training and testing, and evaluation metrics, which encourages active involvement from the community. It is structured to align with European Union regulations, aiming to produce effective large language models that fulfill Europe’s specific requirements. A key feature of this endeavor is its dedication to linguistic and cultural diversity, ensuring that multilingual capacities encompass all official EU languages and potentially even more. In addition, the initiative seeks to expand access to foundational models that can be tailored for various applications, improve evaluation results in multiple languages, and increase the availability of training datasets and benchmarks for researchers and developers. By distributing tools, methodologies, and preliminary findings, transparency is maintained throughout the entire training process, fostering an environment of trust and collaboration within the AI community. Ultimately, the vision of OpenEuroLLM is to create more inclusive and versatile AI solutions that truly represent the rich tapestry of European languages and cultures, while also setting a precedent for future collaborative AI projects.

Mistral Large 3 is a frontier-scale open AI model built on a sophisticated Mixture-of-Experts framework that unlocks 41B active parameters per step while maintaining a massive 675B total parameter capacity. This architecture lets the model deliver exceptional reasoning, multilingual mastery, and multimodal understanding at a fraction of the compute cost typically associated with models of this scale. Trained entirely from scratch on 3,000 NVIDIA H200 GPUs, it reaches competitive alignment performance with leading closed models, while achieving best-in-class results among permissively licensed alternatives. Mistral Large 3 includes base and instruction editions, supports images natively, and will soon introduce a reasoning-optimized version capable of even deeper thought chains. Its inference stack has been carefully co-designed with NVIDIA, enabling efficient low-precision execution, optimized MoE kernels, speculative decoding, and smooth long-context handling on Blackwell NVL72 systems and enterprise-grade clusters. Through collaborations with vLLM and Red Hat, developers gain an easy path to run Large 3 on single-node 8×A100 or 8×H100 environments with strong throughput and stability. The model is available across Mistral AI Studio, Amazon Bedrock, Azure Foundry, Hugging Face, Fireworks, OpenRouter, Modal, and more, ensuring turnkey access for development teams. Enterprises can go further with Mistral’s custom-training program, tailoring the model to proprietary data, regulatory workflows, or industry-specific tasks. From agentic applications to multilingual customer automation, creative workflows, edge deployment, and advanced tool-use systems, Mistral Large 3 adapts to a wide range of production scenarios. With this release, Mistral positions the 3-series as a complete family—spanning lightweight edge models to frontier-scale MoE intelligence—while remaining fully open, customizable, and performance-optimized across the stack.
