Anthropic 推出了其最新的 AI 模型 Claude Fable 5.1 和 Mythos 5.1，旨在解决客户对价格、数据保留和过度安全防护的担忧。据称，Claude Fable 5.1 的性能优于 Fable 5，并且通常便宜约 25%，对于复杂的代理任务，成本甚至可降低多达 45%。这种成本降低得益于对已处理和存储的缓存数据实行了更低的定价。

Anthropic says its newest AI models, Fable 5.1 and Mythos 5.1 , address criticisms from customers about price, data retention, and overzealous safeguards. The company claims Claude Fable 5.1 offers stronger performance than Fable 5, but costs around 25 percent less typically and up to 45 percent less for complex agentic tasks, thanks to reduced pricing on cached data that was already processed and stored.
Along with the announcement, a slew of early impressions popped up, including from Every CEO Dan Shipper, who claims , “It’s the strongest coding model we’ve used, but now it’s fast, token-efficient, and crucially actually speaks like a normal person.”
Box CEO Aaron Levie is another early access believer , saying that his company’s agent with Fable 5.1 picked up on subtleties and ambiguities in data that Fable 5 missed in the same test. Meanwhile, Lisan al Gaib points out that on benchmarks, Mythos 5.1 with low reasoning scores the same as its predecessor set to Max reasoning.
Fable 5.1 also has “more precise safeguards” that Anthropic says are less likely to block basic biology questions than Fable 5, but Mythos 5.1 has the same biology restrictions as the previous model. Anthropic also explained its progress on data retention, saying that Enterprise Frontier Safeguards offer “complete privacy” by storing data on the customer’s cloud servers instead of its own, and will start rolling out later this fall.
Anthropic says it’s “now allowing Fable 5.1 to be used for identifying software vulnerabilities,” but it will still redirect some cybersecurity tasks to Opus models, like “penetration testing, exploit generation, and binary-based vulnerability scanning.” Claude Fable 5.1 is now available on all platforms, while Mythos 5.1 is available to Project Glasswing participants only.
