Today, Mistral announced Mistral 3, a major upgrade to its open model ecosystem featuring three new small dense models (3B, 8B, 14B) and Mistral Large 3, a 41B-active, 675B-total-parameter Mixture-of-Experts model—the company’s most capable release yet. All models are available under the Apache 2.0 license, reinforcing Mistral’s commitment to open, customizable AI for developers and enterprises.

Mistral Large 3: A Frontier-Class Open Model

Trained on 3,000 NVIDIA H200 GPUs, Mistral Large 3 reaches parity with leading instruction-tuned open-weight models and introduces:

Sparse MoE architecture: 41B active parameters, 675B total
Multimodal understanding, including image comprehension
Best-in-class multilingual performance beyond English and Chinese
Full open-weight release in both base and instruct variants

Large 3 debuts as #2 among OSS non-reasoning models on the LMArena leaderboard and will soon be joined by a dedicated reasoning version.

To support efficient deployment, Mistral is releasing an NVFP4 checkpoint (via llm-compressor) optimized for vLLM, enabling the model to run on Blackwell NVL72, or even a single node with 8×A100/H100 GPUs.

Accelerated Through Deep Collaboration With NVIDIA, vLLM & Red Hat

Mistral 3 models were trained fully on NVIDIA Hopper GPUs, leveraging HBM3e memory for frontier-scale training. NVIDIA’s extensive co-design approach enabled:

Optimized inference with TensorRT-LLM and SGLang
Custom kernels for Blackwell attention and MoE
Support for disaggregated prefill/decode and speculative decoding
Scalable deployments from data center to edge via DGX Spark, RTX GPUs, laptops, and Jetson

Red Hat and vLLM partnered with Mistral to improve accessibility and open-source deployment through optimized serving stacks and community-ready tooling.

Ministral 3: State-of-the-Art Intelligence at the Edge

The new Ministral family (3B, 8B, 14B) includes base, instruct, and reasoning variants—each with native multimodal capabilities. Designed for performance, efficiency, and edge deployment, Ministral 3 models offer:

Best cost-to-performance ratio in OSS
Substantial reduction in generated tokens for real-world tasks
Reasoning variants capable of 85% on AIME 2025 (14B model)

This makes the Ministral series ideal for laptops, mobile devices, robotics, and local/private workloads.
