Mistral Shipped an Open-Weight Safety Judge That Takes Its Policy as a Question News
Mistral released Shieldstral 1.0 3B, an Apache-2.0 multimodal moderation model that reads a plain-language yes/no policy question at inference time instead of a fixed harm taxonomy baked into its weights, and runs on a single 16GB GPU.
Mistral's first robot model navigates unseen buildings with a single camera News
Mistral released Robostral Navigate, an 8-billion-parameter model that steers robots through buildings they have never seen using one ordinary RGB camera and a plain-language instruction, beating multi-sensor systems that rely on LiDAR and depth cameras.

Leanstral 1.5 is a free, open model specialized for writing machine-checked mathematical proofs, using a design that keeps only a small slice of itself active at a time.
The quiet race to turn messy documents into AI-ready text News
Mistral released a new document-reading model the same week an open-source rival surged, both chasing the unglamorous job that quietly decides how well AI can read your files.
Voxtral 3 Voice Agents SDK Tool
Mistral’s documented toolkit connects streaming transcription, reasoning, tool calls and speech for phone and web agents; hosted and self-deployment terms differ.
Shieldstral 1.0 3B Tool
Mistral's open-weight multimodal moderation model. You supply the policy as a plain-language yes/no question at inference time rather than retraining for a fixed harm taxonomy, and it returns one calibrated safety score per forward pass. Handles prompts, responses, prompt-response pairs, images and image-plus-text across twelve languages. Apache 2.0, runs on a single 16GB GPU via vLLM, Transformers or llama.cpp; recommended operating context is 32k tokens.
Robostral Navigate Tool
Mistral's 8B embodied model that steers wheeled, legged, or flying robots through unseen environments from a single RGB camera and a plain-language instruction.
