Mistral Unveils 1 Trillion-Parameter Model 'Le Chonk'
French AI lab Mistral has released a new 1 trillion-parameter open-weight model nicknamed Le Chonk, claiming it can compete with leading proprietary models from the US and China.

Introduction to Le Chonk
As tensions mount over who gets access to top-end artificial intelligence , French company Mistral has released a new freely available model that it claims can compete with the very best from the US and China.
The new 1 trillion-parameter model, Mistral Large 4—nicknamed Le Chonk—can be used and customized by anyone. It is currently available in preview, with a final version to follow by the end of the month. Though Le Chonk is built to compete with leading general-purpose models, it is optimized specifically for coding and cyberdefense, as well as tasks particular to manufacturing, finance, electrical engineering, and other niches.
Training and Competitive Positioning
“There are a lot of areas where the other labs will not focus that much,” Guillaume Lample, cofounder and chief scientist at Mistral, tells WIRED. “There are so many domains in which you can improve models.”
Mistral presents Le Chonk as by far the most capable open-weight model developed outside of China, and “very, very close” to some proprietary models. Whereas Chinese labs have been accused by the US government of abusing distillation to close the performance gap with OpenAI and Anthropic, Mistral claims to have trained its model from scratch.
It is already considerably cheaper for businesses to run open-weight models, which cost only as much as the compute they consume. By reducing the performance gap on leading proprietary models and providing a competitive alternative to releases from China, Mistral says, Le Chonk will eliminate the few remaining reasons a business might hesitate to choose open source.
Recent Growth and Financial Milestones
“Mistral is still in the race of getting the best model,” Lample says. “This is the main message.”
With less capital and fewer compute resources than leading US competitors, Mistral has generally lagged behind on model performance, revenue, and the frequency of releases. While some major US labs charge a premium for access to their proprietary, closed-weight models, Mistral generates revenue by charging pay-as-you-go fees for running models through its cloud and deploying engineers to help customers tune models to their specific needs.
Recently, however, the French lab has been on a strong upward trajectory. In September, the company raised a $3.3 billion funding round at a $24 billion valuation, marking the largest ever raise by a European tech company. Its earnings have reportedly increased twentyfold over the past year or so.
Geopolitical Context and Regulatory Shifts
The upswing for Mistral coincides with growing animosity between the US and its transatlantic allies—over issues ranging from tariff policy to the policing of American tech firms—and an increasingly fractious debate over who gets access to frontier-grade AI.
In June, the administration placed temporary restrictions on the distribution of models from OpenAI and Anthropic, citing concerns they could be abused to launch sophisticated cyberattacks. Since then, various incidents have highlighted how models can break free of constraints, leading to weeks of debate over how model releases should be regulated.
The stark reminder that governments could unilaterally revoke access to frontier-grade AI has created an opening for Mistral, a Europe-based lab focusing on open-weight models.
The Value of Technological Sovereignty
“The continental strategy of the EU to become more technologically sovereign … and the increased hostility of the US is a magic formula that all of a sudden puts Mistral—whose performance has not been spectacular—in a favorable position,” Andrea Renda, director of research at the Centre for European Policy Studies, told WIRED.
Reluctant to be pigeonholed into serving only its domestic market, Mistral is eager to emphasize that a lack of fine-grained control over access to AI models could be a problem wherever a business is located—even in the US. By relying entirely on a proprietary model to help repel cyber threats, Lample notes, a business risks the sudden collapse of its defenses.
“Sometimes, people like to make a big deal over the US, versus Europe, versus China. But what really matters is to own the model—even for US companies,” Lample says. “If you use a closed model, there is no guarantee it will still be there tomorrow.”
