Microsoft page confirms Looped Transformers in GPT-6 series

A Reddit user notes that a public Microsoft page confirmed OpenAI uses Looped Transformers in the GPT-6 series, matching earlier reporting by The Information. The page said GPT-6.1 Sol uses two inference passes with a mention of "instead of three," suggesting GPT-6 and 6.1 are post-trained on the same base model; Microsoft later updated the page to remove it.
