I added it to my benchmark based on Mythos-reported bugs, and it's better than GLM 5.1, but still behind several other models, maybe most directly comparable to Qwen 3.7 Max. But, several other open models, including small self-hostable ones (Gemma 4 and Qwen 3.6), found the same number of bugs, 3 of 9. Though it also gets partial credit for reporting one bug in the right spot, but kinda misunderstanding the bug. I also added Kimi K2.7-code in the same run, and it did poorly, consistent with 2.6 performance. Anyway, there are better, cheaper, models on this particular benchmark.

(This small benchmark doesn't prove anything. It's a limited data set and each model only gets one shot at each file in the corpus. But, I find it useful for quickly sussing out if a model can reason about pretty complicated problems in code.)
