Anthropic 的 Claude Fable 5.1 降低缓存成本但提高每任务价格

作者 PulseAugur 编辑部 · [1 个来源] ·

Anthropic 发布了 Claude Fable 5.1，其缓存读取成本显著降低了 75%，使得涉及重复上下文的任务成本更低。然而，由于更高的“努力”成本，每任务成本约增加了 20%，这在单次请求、高努力场景中占主导地位。这种定价结构意味着 Fable 5.1 对于长期运行的代理任务可能更经济，但对于高强度的单次请求则更昂贵，具体取决于工作负载。 AI

影响 Claude Fable 5.1 的定价变化突显了代理工作负载与高强度单次请求之间的权衡，影响了成本优化策略。
