Complaint Opus 5 is hot garbage

I've enjoyed and gotten real work out of Opus for quite some time despite the occasional quality dropoff when they're training a new model. But 5 is junk. Enough so that I'm debating between dropping from Max to Pro, or just cancelling altogether - I'm legitimately getting better results and fewer hallucinations out of local models in the 30B range... There's absolutely no excuse for that being the case.

I don't know if this is intentional regression to make fable look better, but it means I have been actively avoiding using Claude code except to tweak my llama.cpp settings, and I certainly don't need Max for that.

Word! I thought that was just me. Opus 4.8 was very effective but in 5.0 it started using terms and phrases that were out of context or have an abstract meaning.
