## AI 摘要

预训练从根本上说对前沿实验室以外的任何人都不再有意义。虽然企业和初创公司中有很多人患有"预训练症"以显示"影响力"并获得晋升，但从根本上说，这并不合理。与前沿实验室合作进行提示工程可能会有更高的投资回报率，尽管它不像预训练那样"性感"。

## 正文

Pretraining fundamentally does not make sense anymore for anyone other than frontier labs. Although there are a lot of people at enterprises & startups who have "Pretrainitis" to show "impact" and get promotions， fundamentally， it doesn't make sense.

There is probably higher ROI in partnering with a frontier lab to do prompt engineering， although it isn't as "sexy" as pretraining.
