Mistral Large 4 (Le Chonk): 1.05T-param open-weight MoE

Why it matters

Europe's strongest open-weight challenger to US and Chinese frontier labs; Mistral claims it beats some Chinese open models on cyber and coding.

What you could build with it

A small AI infrastructure startup could build a sovereign-hosted coding and security-review API on the open weights once released on Oct 27, selling compliance-friendly inference to European enterprises that cannot send code to US clouds.

Does it hold up?

Too early to judge — announced today, API preview only; open weights land Oct 27 and no independent benchmark results are published yet.
