Anthropic 发布 Fable 5 和 Mythos 5 模型，被指采用隐蔽安全政策引发透明度与竞争争议

| Tiger Sniff
一如既往，Anthropic还发布了厚厚的系统卡，这次长达319页，披露了一套更复杂、更隐蔽的安全安排：同一代模型能力，被拆分成不同可访问版本；更少受限的Mythos 5只开放给少数可信伙伴；面向公众和企业客户的Fable 5，则在网络安全、生物化学、模型蒸馏、前沿AI研发等领域设置了不同层级的限制。 其中一部分限制是可见的。比如，当用户提出高风险网络安全、生物化学或模型蒸馏相关请求时，系统可能触发安全分类器，把请求回退给能力较弱的模型，并告知用户发生了回退。这种做法虽然会影响体验，但至少逻辑清楚，Anthropic认为这些任务风险较高，所以不提供完整能力，或者只提供较弱模型的回答。 真正的问题出在另一部分，对于“前沿LLM开发”相关请求，Anthropic没有采用公开拒答，也没有明确告诉用户模型被降级，而是通过提示词修改（prompt modification）、引导向量（steering vectors）、参数高效微调（PEFT）等方式，在用户不可见的情况下限制模型的有效性。也就是说，用户以为自己正在调用最强的Claude，得到的却可能是被安全层暗中改写、削弱或引导后的回答。...
