OpenAI just rolled out its group chat feature across all subscription tiers after an initial test period, allowing up to 20 users to simultaneously collaborate with each other and with ChatGPT in the same thread. The details: Shared chats are accessed through invite links, with ChatGPT gauging conversation flow and interjecting when appropriate or directly mentioned. Rate limits apply to AI responses rather than human messages, with the usage counting against the user who triggered the model reply. Privacy features isolate group sessions from individual memory, with ChatGPT not retaining info from collaborative threads or applying personal context. The feature initially launched in four Asia-Pacific markets last week for a test trial and is now expanding to Free, Go, Plus, and Pro tiers. Why it matters: Group projects just got a powerful new collaboration tool for the AI age. It might take some time to get the flow of using ChatGPT alongside friends or coworkers, but in a short time, we’ll likely see (and welcome) contributions from models in collaborative efforts as naturally as any other human participants.
