Developer ivanbezdomny shares hands-on impressions of Opus 5.5: it's his main recommendation for most projects, great for bug fixing and testing, and draws beautiful diagrams — but its strong communication creates the illusion that it's smarter than it is, sometimes messing up basic physics or slipping into word salad (a harsh rebuke snaps it back). He adds that OpenAI models still can't draw or do UI, and he doubts their "better at science" claims.
