They more or less claim this exceeds Claude Sonnet 3.5 on most things, but is worse than Sonnet 3.6, and exceeds all other open models.

Oh and they have a cloud service that will code your apps "in the cloud". But, yeah, at this point, so does my cat.

And, yes, unsloth is on it: https://huggingface.co/unsloth/Mistral-Medium-3.5-128B-GGUF (but 4bit quant is 75G)

Sonnet 4.5 and 4.6*

There is no way it exceeds “all other” open models - but it does exceed all of Mistral’s past models.

You can see it getting blown past by GLM 5.1 and Kimi in this.

Still excited to give it a try

Unfortunately they only compare to old “all other open models”. There are probably over 10 other open models better than it by now.

You mean Sonnet 4.5 and 4.6 riight
