## Summary

OpenAI shares research on how chain-of-thought monitorability, covering no-CoT capability and CoT controllability, changes over the model training lifecycle. The research finds models become harder to monitor through their chain of thought as they scale toward more intelligent systems. OpenAI says further progress in pretraining will require new approaches to monitorability.

interesting research from OpenAI on how AI models are getting more difficult to monitor through CoT, laying out a few reasons. One finding from the blog:

"... we expect further progress in pretraining to require new approaches to monitorability."

> We emerged with unsurprising but sobering findings: as we scale toward more intelligent systems, models are becoming harder to monitor through their CoT. 🧵
