OpenAI has introduced group chats inside ChatGPT, giving people a way to bring up to 20 others into a shared conversation with the chatbot. The feature is now available to all logged-in users after a short pilot earlier this month, and it shifts ChatGPT from a mostly one-on-one tool to something that supports small-group collaboration. OpenAI frames the update as a simple way to plan daily tasks with friends, family members, or coworkers, like setting up a dinner, preparing a trip, or drafting an outline together. But the feature may have broader value for work teams that already use ChatGPT for brainstorming, research, and early project discussions.
