Mistral announced that its 1 trillion‑parameter model, called Le Chonk, is now available in preview. The company says the model can compete with the best proprietary AI from the US and China. Le Chonk is open‑weight, meaning anyone can download and fine‑tune it. It is optimized for coding, cyber‑defense, and niche fields like manufacturing and finance. A final version is promised by the end of October.

## The facts

- Le Chonk has 1 trillion parameters
- Mistral raised $3.3 billion in September 2026

## Why it matters

Businesses can run a high‑capacity model without paying the premium fees that closed‑weight services charge.
