Users are reporting a perceived decline in Anthropic's Claude Opus model performance, particularly after the 4.7 and 4.8 updates. This perceived degradation, termed the "permaspike effect," is attributed to overly strict system rules, inefficient "adaptive thinking" protocols that consume tokens rapidly, and safety over-corrections that hinder the model's ability to follow complex instructions. The sentiment is that while Opus has been heavily tweaked, the Sonnet and Haiku models have been neglected. AI
