I cannot empirically prove it, but I feel like Opus 5 has become more confidently wrong/inaccurate.
Discussing topics from nuclear physics to daily macOS questions, it gives wrong answers, leaves out important details, counterpoints. Only when specifically asked about the things it got wrong or glossed over it continues and adjusts its reasoning. I feel this is dangerous - before I could explore topics with Claude, now I have to know in advance that something is not correct to get more details.
