What Mistral AI announced
On 6 Oct 2026, Mistral AI opened in public preview Mistral Large 4 — public preview now, weights promised by end of October for chat / reasoning work. New large-tier entry from Mistral, in the same early-October cluster as Google's image and embedding releases.
Mistral’s official announcement, on 6 October 2026, calls Large 4 “le Chonk”, a natively multimodal mixture-of-experts model with 1.05 trillion total parameters, launched in public preview on Mistral Studio, with weights promised by the end of October 2026. Note a real discrepancy in Mistral’s own pages: the announcement gives 52 billion active parameters, while other Mistral materials give 49 billion active per token. Check the final model card before quoting either figure as settled. Preview pricing is also two numbers for a reason — $1.36 and $4.18 posted, with $0.68 and $2.09 shown as preview rates — so do not budget on the lower figure as a permanent price.
What it costs, and who can use it today
Price: $1.36 / $4.18 per 1M tokens posted; $0.68 / $2.09 in public preview. Access: Preview. Availability: Public preview, 6 Oct 2026; weights promised end of Oct 2026. A token, where prices are per million tokens, is roughly part of a word; prices are per million tokens processed, not per message. Open-weight means downloadable weights — check the licence for commercial use, because downloadable does not automatically mean unrestricted.
Why it matters
European frontier labs are part of the launch cycle, not a footnote. Mistral Large 4 keeps that track visible.

Official sources are listed first, because a lab’s own announcement or product page is the primary source for price, access and availability. Secondary coverage is listed second, and is never used to upgrade an unverified figure into a settled fact.
