Researcher Questions OpenAI Reasoning Methods

ueaj, a researcher at Pangram Labs, tweeted that OpenAI is probably not using looped transformers. The post allows it might involve something like MoEUT but states that approach would not account for denser reasoning observed in frontier math tasks. ueaj added that the RL signal appears too sparse to achieve high performance with minimal reasoning steps. The message was retweeted by commentator zephyr_z9. The post includes a diagram attachment but provides no further confirmation of any OpenAI architecture.
