What happened
Mistral launched a public preview of Mistral Large 4 (unofficially ML4, 'le Chonk'), a 1-trillion-parameter natively multimodal model with 49B active parameters, available today via the Mistral Studio API; weights are promised by the end of October 2026. It was trained from scratch on 3,800 NVIDIA Grace Blackwell GPUs in Mistral's own European datacenters, and the preview runs on that same infrastructure. Mistral claims state-of-the-art open-model performance in cybersecurity, finance, and law, plus visual grounding beyond frontier closed models, while red-teaming with cybersecurity leaders, vetted partners, and state authorities before weight release.
Why it matters
Builders should test the Mistral Studio preview now if they need coding, agentic, or multimodal capabilities, but treat the benchmark claims as vendor-reported until independent evals exist; do not plan a production migration on 'weights drop end of month' alone. For teams with data-residency or provider-refusal constraints, the European-hosted preview and promised self-deployable weights are the concrete decision points—especially if cyber or incident-response access matters.
Discussion angle
Would you evaluate ML4 now via the Mistral Studio preview, or wait for the promised weights and independent benchmarks? Discuss what would actually make your team switch—self-hosting cost for a 1T/49B-active multimodal model, European-hosted latency/compliance, or the cyber red-team access story.
