Overview
- OpenAI is testing built‑in group chats for ChatGPT in Japan, New Zealand, South Korea, and Taiwan, supporting invite links, profiles, and groups of one to twenty people.
- OpenAI says group threads are separate from private chats, personal memory is not used or created there, and the assistant can be summoned by mentioning “ChatGPT,” decide when to stay quiet, and react with emojis.
- The feature runs on “GPT‑5.1 Auto,” with responses and rate limits dependent on the plan of the group member being answered, which may produce differences across free and paid users.
- Quora’s Poe has launched group chats globally with up to 200 participants and access to more than 200 AI models in a single conversation, including GPT‑5.1, Claude 4.5 Sonnet, Gemini 2.5, and creator‑made bots.
- Poe’s groups sync in real time across devices and support custom bots, and the company says it will iterate on the product based on user feedback as organizations explore collaborative AI use cases.
