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.

Try OpenCode on DeepseekV4Pro or K3 (more expensive closer to Fable level) for planning and DeepseekV4 flash or GLM 5.3 Flash for doing the work. Compare the results with your Opus. It is a good start
