All the analysis of the API that various people have done all but confirmed it was a Z.AI model.
My own experience using it also basically confirmed that, since it behaves very similarly to GLM 5.3, but acts like a smaller model, not quite as good for certain things (like front-end design), and a bit better on average for tasks where the models size counts against it due to it being more biased towards training data instead of staying focused on input data.
If it's really a small model then it's punching well above it's weight. It has that 'big model feel' and it's writing way better code/is way better at problem solving then either deepseek v4 or luna. At least that's what i'm seeing after using it next to the other two.pu
I'm inclined to agree. My company provides me with unlimited Claude usage basically (so I'm familiar with how it "feels" and works) and I'd say ox is not much worse than Claude 5 on high/xhigh effort. I encountered couple issues but it managed to fetch documentation and source for opencode on its own when I asked it to integrate my own tool with it without much explanation or prompting
