Claude Opus 4.6 faces "nerf" allegations
Anthropic's latest flagship model, Claude Opus 4.6, is facing widespread community backlash as users report significant regressions in reasoning depth and "lazy" behavior. The issues appear centered on a miscalibrated adaptive thinking algorithm that provides shallow, instant replies to complex scientific and technical prompts that previously triggered deep analysis.
The perceived "nerfing" highlights a fragile trade-off between compute efficiency and reasoning quality. Reports suggest adaptive thinking triggers are failing to scale effort, leading to premature termination on complex prompts. Users have also documented a 10,000-token cap on extended thinking and failures in basic logic puzzles, though forcing maximum effort in the CLI partially restores performance.
