Mistral Says Its AI Model ‘Le Chonk’ Has Leapfrogged China in the Open-Weight Race

The advances, Mistral says, were made possible by feeding the model increasingly difficult cybersecurity and coding problems, which allowed the trillion-parameter Le Chonk to match or surpass models from leading Chinese labs like DeepSeek and Z.ai.

“It’s a pivotal moment in the global AI leadership race,” Pierre Stock, VP of science at Mistral, told reporters during a press briefing. “It offers frontier capabilities for enterprises and governments to defend against an increasing threat level in cyber.”

The finalized version of Le Chonk is now freely available for anybody to access. After a flurry of AI-related cybersecurity incidents, Mistral claims that it’s important for the West to have its own advanced open-weight models. “You have no guarantee that [Chinese models] won’t behave maliciously. They can be threat vectors,” Stock said.
