Overview
- Group chats let up to 20 people collaborate with ChatGPT in a single thread, now rolling out on mobile and web to Free, Go, Plus, and Pro users in Japan, New Zealand, South Korea, and Taiwan.
- Participants join via shareable invite links, set a brief profile with name, username, and photo, and see group conversations stored in a distinct sidebar section.
- Responses use GPT-5.1 Auto with adaptive routing, and the bot follows multi-person dynamics by deciding when to speak, responding when mentioned, and supporting emoji reactions and custom instructions.
- Group conversations are compartmentalized from private chats, personal memories are neither shared nor updated, and under-18 presence triggers reduced exposure to sensitive content with parental controls available.
- Core tools remain available—search, image generation, file and image uploads, and voice dictation—and rate limits apply only when ChatGPT replies, with each AI response counting toward the prompter’s quota.
