Worth noting that this model, unlike almost all qwen models, is not open-weight, nor is the parameter count exposed. Also odd that it is compared against opus 4.5 even though 4.6 was released like 2 months ago.
If Opus 4.6 was only released two months ago, then it seems reasonable that Qwen hasn't finished fully comparing against the latest Opus.
I wouldn't say "almost all" seeing as -MAX and -Omni models were always closed.
They said in the last paragraph[0]:
