OpenAI Ships 'Dreaming V3' Temporal Memory for ChatGPT

OpenAI / Releasebot·medium signal

OpenAI began rolling out Dreaming V3, its largest memory upgrade since ChatGPT launched, to Plus and Pro users in the US on June 4, with Free/Go users to follow within weeks. The architecture automatically revises stored memories as time passes — e.g., updating 'You're going to Singapore in July' to 'You went to Singapore in July 2026' after the trip ends. It is a notable shift toward time-aware, self-updating agent memory rather than static fact storage.
