Mistral AI Releases 1T-Parameter Mistral Large 4
The multimodal model, nicknamed Le Chonk, is available now only through a public guardrail endpoint, with open weights planned in three weeks.
Mistral AI released Mistral Large 4, a large multimodal model with 1 trillion parameters nicknamed Le Chonk, on October 6, 2026, according to TechCrunch. The model is not yet an open-weight release and can currently only be accessed through a public guardrail endpoint.
Mistral said it plans to make the model's weights available in three weeks, after safety testing is complete. The company also said benchmark results for Mistral Large 4 are still pending.
Mistral trained the model entirely on its own compute using 4,000 Nvidia GPUs.
Funding and positioning
In October 2025, Mistral described its approach as "a third way in AI," a phrase attributed to French president Macron. Dutch company ASML led Mistral's Series C, and Samsung led the company's Series D last month at a €21 billion valuation, about $24.39 billion.
Mistral had recently hosted Chinese models, which the company said was not a pivot into being a mere inference provider.
