I tried out the model it's pretty great, better than ~~gpt5.4~~ gpt-5.4-mini perhaps, atleast close enough to sonnet 5 in performance that I didn't notice much of a gap.

Not really at gpt 5.5 tier though, and probably below glm 5.2...

But most of all it just works for me for most things I tried and it's exceedingly cheap so there is no reason not to use it, if you need a foss model.

Edited: gpt-5.4-mini not the base gpt-5.4

Hy3 DeepSWE - 28%

GPT5.4 xhigh DeepSWE - 52%

A lot of contaminated benchmarks in the blog post about Hy3, needs real testing though I have a distinct feeling it's benchmaxxed like a lot of Chinese models.

I think you’ve got the models wrong…gpt-5.4? I doubt there is any open source mode matching it. Maybe in a year

Yeah I meant gpt-5.4-mini, but GLM 5.2 is pretty close to gpt-5.4 base, and much better than it when it comes to design stuff.

GLM 5.2 already matches GPT-5.4 easily.
