Mistral’s new 1T model aims to leapfrog closed and open rivals

The race between open and closed AI is on, and Europe is still in the mix. On Tuesday, French AI lab Mistral AI has released Mistral Large 4, a new large multimodal model aiming to leapfrog both American and Chinese rivals — following what French president Macron has described as “a third way in AI.”

Amid a growing divide between closed models that can be unplugged and open models that are often made in China, Mistral is positioning ML4 as an alternative to both. Nicknamed Le Chonk in reference to its one trillion parameters, ML4 is definitely not small; but is not an open-weight model yet. For the time being, it can only be accessed via a public guardrail endpoint, but Mistral plans to make its weights available in just three weeks, after safety testing is complete.

“In the meantime, we’ll work with trusted partners and governments to make sure that the open-source weights can be used to defend, but not to [perform] malicious attacks,” Mistral VP Science Pierre Stock told TechCrunch. 

Security concerns have been mounting in recent months, particularly among Mistral’s core audience —  enterprises and institutions. At the same time, an open-weight model is easier to audit, Stock said.

Another important behind-the-scenes aspect is that ML4 was trained entirely on Mistral’s compute; using only 4,000 NVIDIA GPUs “which is two to three times less than our Chinese competitors, and significantly less than the closed source competitors,” Stock said.

With benchmark results still pending, Mistral hopes ML4 will be best in class among open-weight models, especially outside of China, but not only, Stock said. Thanks to focused training, it could also outperform closed models in specific areas that are key to its customers, and where multimodal capabilities can add value.
