**What happened:** Mistral has published the weights of Mistral Large 4, nicknamed Le Chonk. The one-trillion-parameter model was first introduced earlier in October. [TechCrunch](https://techcrunch.com/2026/10/29/mistral-releases-weights-for-its-trillion-parameter-ai-model-targeting-cybersecurity/) reported the release on 29 October.

**The numbers:** Mistral says ML4 performs comparably to GLM-5.3, a Chinese open-weight model, and uses 47% fewer tokens per task than GLM-5.3. It also says ML4 outranks all other open models on Artificial Analysis' Coding Agent Index. These figures are Mistral's own and have not been independently verified.

**The details:** Weights are available on Hugging Face and through Mistral's API. Organisations can deploy the model on-premises. Mistral says it reaches state-of-the-art performance at a fraction of the compute and capital of closed labs.

**Why it matters:** Mistral positions ML4 for sovereign cyber defence. It targets enterprises and governments that want to deploy and control the model on their own infrastructure. The company also highlights agentic coding.

**In their words:** Pierre Stock, Mistral's Vice President of Science, said: "Access that can't be cut off by definition because the model is open-weighted."

**The context:** Stock also addressed the risks of rogue AI agents. He said Mistral does not want to fearmonger people, and that the problem is solvable.

**The catch:** TechCrunch calls the model open-weight but names no licence, so the specific licence terms are unconfirmed. Benchmark results beyond Mistral's own comparisons are also unconfirmed.

**What's next:** Stock said Mistral wants to make this cyber capability available to everyone as soon as possible.

## Key takeaways

- Mistral Large 4 has one trillion parameters and open weights.
- Mistral targets sovereign cyber defence and agentic coding.
- Benchmark claims come from Mistral and are not independently verified.
