Dev says Opus 5.5 degraded: a game he once built in 2 prompts is now impossible
Rasmic · x · 2026-11-09
Developer Rasmic complained that Anthropic's Opus 5.5 has degraded significantly: he shared a screenshot of a GTA-style game scene, saying he previously built a game with these graphics using just 2 prompts — something the model can no longer do. "Shame on Anthropic," he wrote. A first-hand data point in the recurring user complaints about silent model degradation.
