OpenAI deployed GPT-5.5 and its chief scientist Jakub Pachocki publicly stated that AI progress over the past period has been 'surprisingly slow' — a candid admission that the rate of improvement has not matched earlier expectations.
Pachocki promised 'extremely significant improvements' in the medium term, signaling that OpenAI believes the next generation of models will represent major leaps forward — meaning GPT-5.5 may be a stepping stone rather than the next major breakthrough.
For anyone using OpenAI's tools (ChatGPT, API customers, businesses building on the platform), this sets expectations: today's capabilities are closer to the baseline than the ceiling, so critical workflows should plan for major capability upgrades in the coming months rather than betting on incremental gains.
