OpenAI has rolled out group chats to all ChatGPT users worldwide across all of its paid and free plans. Group chats let users collaborate with ChatGPT together in real time. Up to 20 people can participate in each chat by accepting an invitation or joining through a shared link. The feature changes ChatGPT from a one-on-one assistant into a space where many can work on a project together.
To start a group chat, users tap the people icon. Everyone sets up a profile with their name, username, and photo. When someone joins an existing chat, ChatGPT creates a new conversation while leaving the original chat unchanged.
ChatGPT automatically decides when to respond and when to stay quiet based on the conversation’s context. Users can tag ChatGPT to get a response, and it can react with emojis and reference profile photos. Group chats run on GPT-5.1 Auto, which picks the best model based on the prompt and each user’s plan.
Personal ChatGPT memory and settings stay private and are not shared in group chats. ChatGPT does not create memories based on group chats. For users under 18, ChatGPT automatically reduces exposure to sensitive content, and parents can disable group chats through parental controls.
