## AI 摘要

Sapient Intelligence 发布并开源自主科研系统 PRAXIST Beta，通过并行 Research Peers 与共享研究图谱跨代累积实验证据。在完整 75 任务 MLE-bench 上，PRAXIST（deepseek-v4-pro）获 49 金、共 60 枚奖牌，超过 Claude Opus 4.8 的 34 金、55 枚。

## 正文

Sapient Intelligence released PRAXIST Beta, an autonomous R&D system that carries experimental evidence across generations.

On the full 75-task MLE-bench:
• Sapient's PRAXIST got 49 gold medals and 60 medals overall for PRAXIST using deepseek-v4-pro.
• Claude Opus 4.8 reached 34 gold and 55 total

And PRAXIST is open source starting today

Instead of keeping only the best candidate, PRAXIST runs parallel Research Peers and stores findings, failures, evidence strength, and lineage in a shared research graph.

That graph lets later experiments reuse validated mechanisms, retest weak claims, and combine useful discoveries from different research branches.
