We've all heard people say that Qwen is near-Opus level, but I have receipts and am here to be transparent with you.
Opus 5 is a great model. It's not great enough.

Unpopular opinion: Opus 4.7 isn't the problem. The problem is a $200/mo "Max" plan that burns out in 15 minutes of real coding.

I ran this in progressive mode w/Opus4.6 on a paper where refine.ink had given me very useful feedback. It caught many of the same minor issues! Main difference was in high level feedback-with refine it was much closer to what I'd expect from experts. But not bad for a fraction of refine cost! (~$3)
