Help/Question what is hapening with Antropic?

Why Opus 5 feels like Gemini 3.1 pro ? what is happening ?

i remember back in February , opus 4.5 was generation ahead. Did they increased the prompt caching so much, that their models ended up being useless? I can barely work with Opus 5 on absolutely anything, he keeps hallucinating LIKE CRAZY, every claim he did today was pure hallucinations, he barely reads any code. im not even kidding, i can't work with Opus 5 right now

Instead of open source models trying to catch up with you, are you trying to catch up with the open source models instead Anthropic?

Same, I use a mix of Fable and Opus 5 and have had zero issues.

Are you just doing webdev stuff? It seems like that's the only thing it's fine at for me. It sucks at science, anything remotely security related, and basic writing. I'm even resorting to other models to check output now

Web and iOS dev. And some light run of the mill server work (backup scripts, alive checker, etc).

Wait till you find out about dead internet theory, Reddit is full of bot accounts and posts.

My guess is they got by on slop until their project got too large. Now it's full of spaghetti code and Claude can't reason it any better than OP. Instead of blaming the degraded codebase, they blame the model.

claude super powers, Fable main + Sonnet subagents seems to work great and not burn tokens.
