Mistral launches Large 4 preview with 1 T parameters
Mistral is putting its biggest model into API preview now, with open weights promised by month’s end.
Large 4, nicknamed “le Chonk,” is described as a natively multimodal MoE model with 1T total parameters and 49B active. The piece says it targets software engineering, cyber, finance, law, science, and manufacturing, with benchmark claims across DeepSWE, AutomationBench, cyber tests, legal and financial tasks, and visual grounding. Mistral says it is red-teaming the less-restricted model with cyber leaders, vetted partners, and state authorities before releasing weights. API pricing is listed at $1.36 per million input tokens and $4.18 per million output tokens. TestingCatalog's note
