Opus 5.5 首发日 vs 今日：同一提示词视频质量对比
作者用同一 Lander 提示词和参考图，对比 Opus 5.5 首发日与今日生成的太空视频，称今日版本渲染出错、子弹物理变差、飞船解体物理消失、运镜切换缺失，并翻代码找原因。
Last time we posted that Opus 5.5 got nerfed, we got a lot of criticism, so we ran one more test. We tested Opus 5.5 on launch day and again today using the exact same Lander prompt and reference images. Launch day vs today below : Today’s version has rendering glitches, worse bullet physics, missing spacecraft break-apart physics, no camera toggles, and a worse UI. We also inspected the code and found some questionable implementation choices that explain the regressions. LLMs are non-deterministic, but this isn't a minor variation. The results are clearly worse. Anthropic, what changed? Is this just a marketing strategy for the launch of Fable 5.5?
