The news: OpenAI is rolling out a group chat option for ChatGPT to all logged-in Free, Go, Plus, and Pro users globally.

• The company said in a blog post that the feature is intended to help users collaborate with one another in the same conversation—such as working with friends, family, or coworkers on plans, decisions, and brainstorming.
• Group ChatGPT was trained to follow the flow of conversations and know when to respond and when to stay quiet, though users can tag it within the chat to prompt a response.

Zooming out: The update marks a major step toward a more interactive OpenAI ecosystem, a direction the company has been pursuing for some time. OpenAI’s Sora app already lets users create and remix videos with an AI-only feed where every clip is machine-made, though direct user-to-user engagement between users isn’t available.

ChatGPT’s unique visitors grew 48.9% from 41.5 million in January to 61.8 million in August, per Comscore, and collaborative features like this could help boost its use cases.

What it means: After establishing chatbots as the dominant entry point for consumers to interact with genAI, OpenAI is trying to deepen engagement by making ChatGPT a social, shared experience rather than a single-user tool.

• Group chat shifts ChatGPT from a personal assistant to a shared workplace that could compete with Slack or Google Docs.
• It also introduces a network effect: As more people use the platform together, OpenAI gets more platform stickiness and opportunities for multi-user features.

Why it matters: Group chats give marketing teams a faster way to brainstorm with AI in real time, such as when working on campaign concepts, audience insights, or content planning in a low-friction environment.

Because teams can customize how ChatGPT behaves in different groups—like dialing down sycophancy for ideation or setting a specific communication tone—the tool can customize the style of assistance it gives for different tasks.

What marketers should do: Expect that audiences will increasingly discover, remix, and create content together inside AI environments, potentially changing how users find and discuss products. To capitalize on this new engagement tool, marketing leaders should:

• Start experimenting with group-based AI workflows. Use group chats for campaign ideation or rapid prototyping, with AI serving as the meeting’s sounding board.
• Prepare for new discovery channels. As more content creation and engagement happens within AI platforms, anticipate future platform opportunities for visibility, such as AI feed integrations.
