Claude Opus 4.6 被削弱传闻通常可归为三类：推理栈或 Claude Code 变更导致的无意回归；量化、减少推理等有意"优化"（若属实应明确告知付费用户）；以及"用得越多感觉越笨"的用户心理效应。
Seeing rumors that Claude Opus 4.6 got nerfed.
Usually this boils down to 3 cases：
- Unintentional. For example， a regression caused by changes in the inference stack or Claude Code. This is what evals are for before rolling out.
- Intentional "optimizations" （quantization， reduced reasoning）. If so， say it. If users pay for a model， they should get that model.
- User psychology. The more you use a model， the dumber it feels.
