Anthropic 推出了 Claude Fable 5.1 和 Claude Mythos 5.1，被誉为全球最先进的编码和知识工作模型。这些新模型在各项基准测试中树立了新标准，其中 Claude Mythos 5.1 在 Terminal-Bench-Science 0.1 上得分 52.6%，在 Terminal-Bench 4.0 上得分 55.8%。这表明它们比 Fable 5 有显著提升，并且在较低工作量水平下，这些模型还能以更低的成本实现相似或更优异的结果。
We're introducing Claude Fable 5.1 and Claude Mythos 5.1, the world's most advanced models for coding and knowledge work.
Fable 5.1 excels at complex, long-running tasks. And its research capabilities offer an early glimpse of how AI models will contribute to scientific progress.
Across our benchmarks, the model sets a new standard. It scores 52.6% on Terminal-Bench-Science 0.1, more than double Fable 5. On Terminal-Bench 4.0, it scores 55.8% against 42.0% for Fable 5. As well as being capable of much higher performance than Fable 5, it can also achieve similar or better results at a much lower cost when set to lower effort levels.
Cache reads with Fable 5.1 cost 75% less than Fable 5's. This reduces the cost of the model in practice by around 25% for typical workloads, and up to 45% for highly agentic ones.
We've also improved our safeguards. Our cybersecurity safeguards now flag benign requests about 60% less often. On basic biology and medical questions, we've recently reduced the fallback rate by around 85%.
Claude Fable 5.1 is available everywhere today. Claude Mythos 5.1, our model for cyberdefenders and life scientists, is available through trusted access programs.
