OpenAI moving to a faster, «iterative» release schedule for new models

GPT-5.5 came out just six weeks after GPT-5.4, so naturally, people are wondering if this is part of a new trend of quicker releases:

— Yes, we expect quite rapid continued progress, says OpenAI Chief Scientist Jakub Pachocki on a call related to today’s release, according to Tae Kim on Substack.

— We see pretty significant improvements in the short term, extremely significant improvements in the medium term, he adds.

Sam Altman has also weighed in, saying that «We believe in iterative deployment; although GPT-5.5 is already a smart model, we expect rapid improvements.»

Altman goes on to say that this is also part of a safety strategy, arguing that iterative releases make it easier for the world to prepare for advances in AI.
