Users compile list of Claude Opus 5 complaints: best on benchmarks, worst to work with

A viral thread by @Ananth7e compiles consistent user complaints about Claude Opus 5: extremely verbose, overly apologetic and hedging, argues with instructions, invents weird jargon, does far more than asked, introduces subtle bugs that pass tests, confidently wrong then messes up fixes, and feels worse than Opus 4.8 for daily workflows. It remains strong at frontend, UI, and 3D work. The takeaway: best on benchmarks, worst to actually work with. Quoting the thread, @gerardsans argues this is the end of the "just scale more" game — benchmarks soar while daily usability collapses and users cancel.
