OpenAI has launched Dreaming V3, an update that significantly improves ChatGPT's memory. Now available for free, the system can recall data from past conversations, such as food allergies or details of ongoing projects, without needing to repeat the information. This promises to streamline interactions and reduce the usual friction of having to re-explain the context each time a new dialogue with the assistant begins.
How the new persistent memory system works 🧠
Technically, Dreaming V3 employs an extended attention mechanism that indexes key fragments of previous conversations. Instead of storing the entire unfiltered history, the model prioritizes relevant data such as user preferences or work milestones. This information is integrated into the current session's context through a semantic compression process, allowing the assistant to access it without saturating short-term memory. The result is a smoother experience, where the model remembers what's important without losing responsiveness.
Now even the AI will remember that you hate broccoli 🥦
Finally, you can stop telling ChatGPT that you're allergic to shellfish or that last week's project is still on hold. But beware, because if you ever confessed your obsession with 90s TV shows, get ready for it to recommend Friends every three messages. Sure, at least you won't have to remind it that you quit coffee: now it will know, even though you can no longer deny it. Selective memory also has its dark side.
