Running the same day as the 339-upvote Opus 5 complaint thread, a smaller post (64 upvotes, 33 comments) from a builder who called Opus 5 'shite' and 'like a very drunk Opus 4.8' for two weeks reports that switching to Opus 5 Ultracode produced 'a glimpse of the late beauty that was Fable,' with hours of work on the Pro plan and no limits hit. A commenter's caution is the useful detail: an unfamiliar first run of ultracode spawned roughly 40 simultaneous agents. Taken together with the backlash thread, the emerging practitioner read is that Opus 5's perceived regression is partly a mode-selection problem, not purely a model-quality one.
