Overview
- Group chats are rolling out to all logged‑in users on Free, Go, Plus and Pro plans globally over the coming days across web and mobile.
- Up to 20 participants can collaborate in a single thread, with group conversations kept separate from personal chats and no personal memories carried over or created.
- Responses in groups use GPT‑5.1 Auto, which selects a model based on the prompt and the recipient’s plan, and usage limits count only when the AI replies.
- ChatGPT has been trained to read group dynamics, stays quiet unless needed, can be summoned by tagging “ChatGPT,” supports emoji reactions and requires a simple profile for participants with invite‑by‑link access.
- Several advanced tools are not yet supported in group threads, and safety measures reduce sensitive content if a minor is present with parental controls available; separately, OpenAI launched a FERPA‑aligned ChatGPT for Teachers with provisional free access through June 2027 and about 150,000 U.S. educators onboarded.
