New Anthropic research: Persona vectors.Language models sometimes go haywire and slip into weird and unsettling personas. Why? In a new paper, we find “persona vectors"—neural activity patterns controlling traits like evil, sycophancy, or hallucination. https://t.co/PPX1oXj9SQ ...

Research Findings - Anthropic Research 发现，在某些情况下，更长的推理时间会导致准确率降低 [1] - 研究表明，简单地增加测试时的计算量可能会无意中加强有问题的推理模式 [1] Implications - 行业应警惕测试时计算的逆向扩展现象，即计算资源增加反而导致性能下降 [1] - 行业需要更深入地研究和理解推理过程，以避免因盲目扩展计算资源而产生负面影响 [1]

We're happy to receive applications from Fellows affiliated with other organizations (e.g. you can participate while in a PhD program).And finally, a Fellowship will stand you in good stead for roles at Anthropic: we plan to extend some full-time offers to completed Fellows. ...
