A reply says Opus 5's coding performance improves noticeably when it is given high or xhigh effort.
It cites FrontierBench, CursorBench, ProgramBench, and the AA Coding Agent Index, arguing that more test-time compute helps the model verify more thoroughly, produce stronger solutions, and generalize better to novel tasks.
