Claude Fable 5.2 以 174 分刷新 Epoch Capabilities Index 纪录
Anthropic 的 Claude Fable 5.2 把 Epoch AI 的能力指数推到 174，比 OpenAI 的 GPT-6 Astra 高 5 分。关心两家模型实际能力差距、以及模型自主做 AI 研究这个话题的人，这篇值得点开看看 Epoch 的后续工作。
Epoch AI 宣布 Claude Fable 5.2 在 Epoch Capabilities Index（ECI）上取得 174 分，创下该指数历史最高纪录。此前的最高分是 GPT-6 Astra 的 169 分，Fable 5.2 超出 5 分。此外，Fable 5.2 的成绩还高于 pre-Astra 阶段推理模型的趋势线预测值，说明其能力提升快于既有曲线。
Epoch AI 指出，这一成绩基于其在模型发布前使用自家基准进行的独立测试。ECI 是一个持续更新的综合能力指数，随着更多基准测试结果的公布，分数可能会发生调整。Epoch AI 同时提到，考虑到近期关于 AI 参与 AI 研发（AI R&D）的讨论升温，团队希望尽快发布该方向的更多研究工作。
Claude Fable 5.2 sets a new record on the Epoch Capabilities Index (ECI) at 174. The previous high was GPT-6 Astra’s 169. Fable 5.2’s score is above what the pre-Astra trend for reasoning models would have predicted.
This is notable given recent discussion of AI contributions to AI R&D, and we hope to release more work in this area soon.
This is based on testing we did prior to launch using only our own benchmarks. The ECI is continually updated as more benchmark results become available, and may change in the future.
