Our Commentary ​

"Le chonk" indeed! Mistral Large 4 sounds like a beast. A trillion parameters, and the promise of open weights? That's a huge deal for the open-source AI community. It's great to see Mistral pushing the boundaries and staying competitive, even if they're still a bit behind the absolute frontier. The "pelican" test is a fun way to illustrate progress.
