Mistral patented letting the model write the tool call as code News
Mistral AI holds a granted US patent, "Code implemented tool calls," covering an agent architecture in which a model writes a code block wrapping tool calls, a server runs it in a sandbox, pauses at each external call, and resumes with the result substituted in.
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.
Mistral releases a lean, open model built for formal math proofs News
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.
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.
Mistral OCR 4 Tool
A hosted document-reading model that converts scanned pages, PDFs, and complex layouts into clean structured text ready for a language model. Send a document, get back tidy text with the structure preserved.
Leanstral 1.5 Tool
A free, open mixture-of-experts model specialized for writing machine-checked Lean 4 proofs and translating ordinary math into formal, verifiable form.
