Bug Description
I already fallback to Opus4.6
Using chinese as input with Opus5 is terrible, Opus5's response in no readable, not native chinese, a lots of weird metaphor (this also happens when using english as prompt)
and the coding experience with opus 5 is also terrible, why always over comment? write 1 line code with 10 lines of comment? is not human readable, hard to code review it's output.
