Opus 5 gets called a “generational bullshitter” in a model-behavior gripe thread

The post quotes a user saying “Opus 5 is a prime bullshiter” and joking that whoever wrote the rubrics should be promoted to sales. The reply adds that since around 4.8, every Opus version has felt increasingly adversarial by default outside agent contexts.

The complaint is specifically about ordinary, slightly subjective spot-check prompts: instead of neutral answers, the model often responds with dramatic, contrast-heavy phrasing like “BUT ONLY ONE IS TRUE, AND HERE’S WHERE IT STINGS:”.
