Latest update (11-12 10:02): OpenAI research finds reasoning models are harder to monitor through chain-of-thought

Overview: OpenAI publishes research finding that AI models become harder to monitor through their chain of thought as they scale toward greater intelligence. The study measures chain-of-thought monitorability using two properties, no-CoT capability and CoT controllability, across the model training lifecycle.

According to Sebastian Raschka's summary of OpenAI's thread, better pretraining raises no-CoT capability while architecture mostly does not matter, and reinforcement learning alone raises controllability, which distillation passes on. Raschka says both trends make monitoring harder. OpenAI says further progress in pretraining will require new approaches to monitorability, and its thread calls the findings sobering.
