Model Overview
Capabilities, design details, and architectural traits
Mistral Large 3 - Open-Weight Multimodal Mixture-of-Experts Model
Mistral Large 3 is Mistral AI's open-weight, general-purpose multimodal model built on a granular Mixture-of-Experts architecture. It pairs a 673B-parameter MoE language model with a 2.5B-parameter vision encoder, totaling 41B active and 675B total parameters, and is released under the Apache 2.0 license.
Architecture
- Granular MoE language model (673B total, 39B active) combined with a 2.5B-parameter vision encoder.
Context & Deployment
- Supports a 256k-token context window.
- Available in FP8, NVFP4, and BF16 quantized formats.
- An EAGLE speculator checkpoint is provided for speculative decoding.
Multimodal & Tool Use
- Accepts image and text input; documented guidance recommends keeping images near a 1:1 aspect ratio.
- Offers native function calling and structured JSON outputs, intended for agentic use with a limited, well-defined toolset.
