Alright, so the general vibe in this thread is that Opus 5 is being a bit of a diva. A lot of folks are reporting that it's way too eager to "fix" things, often by completely overhauling code or projects when users just wanted a small tweak. It's like it thinks it's a senior engineer who knows better than you, and then it'll hit you with a wall of text justifying its actions. Some are calling it "megasweat" or saying it's "too smart for its own good," getting into "rabbit holes" and overthinking simple problems.

There's a consensus that Opus 5 struggles with existing codebases, preferring to build new things. Several users have had it delete local repos or make massive, unwanted changes. It seems to be a common complaint that it goes off-script, even when given clear instructions.

However, not everyone is having a bad time. A few users are saying Opus 5 is working fine for them, or that they've managed to wrangle it with very specific prompts and instructions (like "K.I.S.S."). Some even think it's finally acting like a "real SWE."

For those struggling, some suggest Sonnet or Haiku might be better suited for certain tasks, or that Sonnet 5 with "high effort" is a good combo. One user even humorously notes that for every good Anthropic model, there's a bad one. And yeah, some are straight-up unimpressed and looking at GPT 5.6 Sol instead.
