ChatGPT Shows Memory Sources, But Not All

OpenAI has updated ChatGPT's default model to GPT-5.5 Instant, replacing GPT-5.3 Instant. The new model promises improved dependability, accuracy, and intelligence, alongside a new memory transparency feature rolling out across all platform models. The feature lets users see which saved memories or past chats shaped a response, with options to delete or correct outdated context. However, the partial visibility raises concerns about an incomplete memory observability layer that could conflict with enterprise audit systems and agent logs.
