Overview
- Group chats are now available to all logged‑in ChatGPT users across Free, Go, Plus and Pro tiers with support for up to 20 participants and link‑based invites.
- OpenAI trained new social behavior so the AI can follow multi‑person conversation flow, stay quiet when appropriate and respond when @ mentioned.
- Personal ChatGPT memories are kept separate from group conversations, and creators’ memories are not shared with other members.
- Group threads add management tools and collaboration features including a grouped sidebar view, nicknames, mute, add/remove members, file and image support, voice input, search and per‑group custom instructions.
- Separately, OpenAI released a teacher edition for U.S. K–12 staff free through June 2027 that offers GPT‑5.1 Auto and classroom tools with FERPA‑aligned handling of student data.
