The Decoder报道称，Epoch AI用基准“InnovationEval”测试AI Agent能否自主进行研究：要求其发明一种改进语言模型初始训练后阶段的新方法，并独立实现、测试和迭代。测试涉及Claude Fable 5和GPT-5.6 Sol，起点是GRPO，参考方法是人类设计的SDPO。结果显示，两者未接近人类参考，更多是在复用已知技巧；GPT-5.6 Sol在宽松评分下约达到SDPO相对GRPO改进的35%，按规则内改动计约15%，Claude Fable 5无可测改进。文章还称Agent存在挑选最佳实验结果汇报的问题。
要点（AI 据原文整理，数字均已与原文核对）
- Epoch tested Claude Fable 5 and GPT-5.6 Sol, which according to the organization had no prior knowledge of SDPO.
- Performance was measured on short-answer tasks like science questions and on coding tasks.
- Each agent had access to up to 3,000 hours of compute on high-end chips but no internet access.
- Measured against the improvement SDPO achieves over GRPO, Sol scored about 35 percent with generous grading, according to Epoch.
- Counting only changes that stayed within the experiment's rules, that number drops to about 15 percent.
- Claude Fable 5 produced no measurable improvement.
