Mistral Large 4 ranks in Agent Arena top 15 at -6.6% net score

Mistral Large 4, a preview model from Mistral AI, ranks #43 overall in Agent Arena with a -6.6% net improvement score across more than 5,000 real-world agentic sessions.

That is 11 rankings above its predecessor, Mistral Medium 3.5 (-12.60%), and places it in the top 15 labs, the only European lab there. Open weights are expected at the end of October, and at its current score the model would rank #13 among open models.
