Mistral Large 4 Preview (Le Chonk) scores 38 on AA intelligence score. a bit underwhelming, but I’d welcome anything coming out of EU at this point: > 1T, multimodal, with 49B active > open weights released by the end of October > it’s still being RL-trained > the final version is expected to be much better > trained on 3,800 NVIDIA Grace Blackwell GPUs in European data centers

Not so impressed with the performance, tbh. I suspect many will feel the same given what we have recently seen with Kimi, Qwen, DeepSeek, GLM, etc. But you know what. That's okay! What we need is more efficient, diverse, customizable frontier open-weight models. It's great to see Mistral back in the game. I like what I see in the multimodal capabilities. That's where I think Mistral Large can stand out. Cyber could also be an interesting direction for them.
