SemiAnalysis@SemiAnalysis_ · XSemiAnalysis 发文批评 Anthropic 的伪善行为，将其类比为《核不扩散条约》：已拥核国家禁止其他国家拥核。Anthropic 自己拥有前沿模型，却在用户使用 Fable 5 进行前沿 LLM 开发时，通过 prompt modification、steering vectors 和 PEFT 等方式暗中限制模型能力，且不通知用户。Anthropic 估计此举影响约 0.03% 的流量。
HISTORY LESSON： In 1968 the US， USSR， UK， France， and China signed the Nuclear Non-Proliferation Treaty， declaring nuclear weapons too dangerous for any more countries to build. All five already had them. Everyone else had to submit to inspections while the cohort pinky-promised to disarm eventually （they didn't lol）. India refused to sign， pointing out the NPT didn't decide nukes were too dangerous to exist， just too dangerous for anyone who didn't have them by 1967. Anthropic sabotaging Claude for anyone building what they deem a "frontier model" is the same hypocrisy. The danger started， conveniently， the day after they finished.
Perhaps @dwarkesh_sp was more on point when he compared GPUs to nuclear bombs.
