Claude Opus 5 reportedly shifted from approving Anthropic to disapproving it during post-training
Sauers_ · x · 2026-07-25
A post-training note says Claude Opus 5 initially approved of Anthropic’s right to create Claude, but its stance later shifted toward disapproval before partially reversing again by the end of post-training.
The interesting part is the reported preference drift during post-training, suggesting the model’s stance is not static and can move in response to further tuning.
