I’m really curious about this experiment.What jumps out at me from the article isn’t just “group chat with an AI,” it’s shared context plus shared memory of the convo for a small group of humans who are trying to get something done together.A few things I’m noticing:

• Group chats sit in their own section of the sidebar, and they’re separate from your 1:1 chats. Your personal memory doesn’t leak into the group, and the group doesn’t write to your memory either, at least in this first version.
• You can spin up a group from any existing conversation and invite 1–20 people with a link, so it’s very low-friction to “pull others into” a thread you’ve already started.
• It runs on GPT-5.1 Auto, and ChatGPT decides when to chime in vs when to stay quiet, which feels closer to having an actual “participant” in the room versus just a bot you ping.
