Meet Mistral Large 4, aka Le Chonk. • 1T parameters, natively multimodal. 49B active. It is the best open weights model from US or Europe on aggregated benchmarks. • State-of-the-art on critical workloads, including cyber defense, manufacturing and finance and it surpasses closed frontier models on visual grounding. • Forged in Europe end-to-end and is deployable from Europe via our own Mistral Cloud infrastructure. • Available to all via API today. Working with cybersecurity partners privately. Open weights release end of October.

We can finally talk about it: We found a way to extract hidden reasoning of frontier models using a vulnerability in the APIs of every frontier AI company. We verified that our reasoning token count matches billed API thinking tokens 1:1 for most of the prompts we queried.

Muse Spark scores 33% pass@5 on our ZeroBench.🚀 Glad to see models getting further away from "zero". zerobench.github.io/
1/ today we're releasing muse spark, the first model from MSL. nine months ago we rebuilt our ai stack from scratch. new infrastructure, new architecture, new data pipelines. muse spark is the result of that work, and now it powers meta ai. 🧵

🚀 New paper! arxiv.org/abs/2511.16655 Recently, Cambrian-S released models & two benchmarks (VSR & VSC) for “spatial supersensing” in video! We found: 1️⃣ Simple no-frame baseline (NoSense) ~perfectly solves VSR! 2️⃣ Tiny sanity check collapses Cambrian-S perf to 0% on VSC! 🧵👇

🚀New Paper! arxiv.org/abs/2504.07086 Everyone’s celebrating rapid progress in math reasoning with RL/SFT. But how real is this progress? We re-evaluated recently released popular reasoning models—and found reported gains often vanish under rigorous testing!! 👀 🧵👇
