Claude Fable 5在编程和推理任务上创下新高，但高昂成本和严格过滤让开发者需要权衡。做AI应用或自动化流程的团队，建议先评估预算和合规需求再决定是否接入。
Anthropic推出了Claude Fable 5，这是其新Mythos模型系列的首款产品。该模型在几乎所有基准测试中领先，包括SWE-bench Verified达到95%，但价格是Opus 4.8的两倍，每百万token收费10或50美元。严格的安全过滤器会阻止约9%的请求，并且新的30天数据保留政策甚至适用于零数据保留合同。这标志着Anthropic在追求极致性能的同时，也加强了安全控制和商业化策略。
Claude Fable 5: The first Mythos model is powerful, expensive, and heavily filtered
Anthropic has released Claude Fable 5, the first model in its new Mythos class. It leads nearly every benchmark, including SWE-bench Verified at 95 percent, but costs twice as much as Opus 4.8 at 10 or 50 dollars per million tokens. Strict safety filters block about nine percent of requests, and a new 30-day data retention policy applies even to zero-data-retention contracts.
