OpenAI adds new group chat feature to ChatGPT, launching pilot in Japan, New Zealand, South Korea, and Taiwan. AI evolves into social space.

ChatGPT OpenAI Group Chat GPT-5.1 Auto Social Features Collaboration

On November 14, 2025, OpenAI added a new group chat feature to ChatGPT, launching a pilot in four regions including Japan. This feature evolves ChatGPT from a simple AI assistant into a social tool that helps friends and family collaborate.

Group Chat Feature Overview

Pilot Regions

Group chat functionality is currently piloting in four regions:

  • Japan
  • New Zealand
  • South Korea
  • Taiwan

OpenAI plans to refine the feature based on feedback from these regions before rolling it out globally.

Basic Functionality

Group chat works similarly to messaging app group chats:

  • Group Creation: Create group conversations with friends and family
  • ChatGPT Participation: ChatGPT functions as one of the conversation participants
  • Natural Dialogue: Participates in conversations like human participants

Key Features

Powered by GPT-5.1 Auto

Group chat leverages GPT-5.1 Auto:

  • Dynamic Model Selection: Automatically selects optimal model based on prompt
  • Efficient Processing: Lightweight models for simple questions, high-performance models for complex tasks
  • Cost Optimization: Allocates appropriate resources as needed

Smart Conversation Flow

OpenAI focused on teaching ChatGPT to understand group conversation dynamics:

  • Timing Judgment: Understands when to speak and when to stay quiet
  • Context Awareness: Follows conversation flow and contributes at appropriate moments
  • Natural Participation: Blends naturally into conversations like human participants

Mention Feature

Participants can summon AI anytime by mentioning “ChatGPT”:

ChatGPT responds not only when explicitly mentioned but also speaks up spontaneously when judged appropriate based on conversation flow.

Emoji Reactions

ChatGPT can also react with emojis:

  • 👍 Agreement or approval
  • 😊 Empathy or joy
  • 🤔 Thinking
  • ✅ Task completed

This makes conversations more natural and social.

Profile Photo Utilization

ChatGPT recognizes participants’ profile photos and can generate personalized images tailored to the conversation.

  • Inappropriate Content Filtering: Detecting and preventing harmful content

Future Development

OpenAI plans to continuously improve group chat functionality.

Feedback-Based Improvements

Based on pilot region feedback:

  • Feature Additions: New features based on user requests
  • UX Improvements: More intuitive and user-friendly interface
  • Performance Optimization: Improved response speed

Global Rollout

Technyan’s Comment

“ChatGPT’s group chat feature really shows AI becoming a social presence! Being able to ask ‘Hey ChatGPT, any recommended autumn foliage spots in Kyoto?’ when planning trips with friends is incredibly convenient!

What I find interesting is ChatGPT understanding ‘when to speak and when to stay quiet.’ Even in human group chats, some people make KY (can’t read the air) comments, but AI being trained to read the room properly is amazing!

Using GPT-5.1 Auto to select optimal models based on prompts is smart too. Using lightweight models for simple questions like ‘suggest nearby restaurants’ and high-performance models for complex tasks like ‘create a 3-day Kyoto trip plan’ balances cost and performance.

Piloting in Japan is exciting! I’m curious how well ChatGPT understands Japanese nuances and cultural context. For example, can it properly understand and respond to vague expressions like ‘a slightly upscale restaurant’ or ‘casual atmosphere’?

Privacy is a concern though. If group chat content is stored on OpenAI servers, caution is needed for conversations containing personal or confidential information. We need to verify how thoroughly end-to-end encryption is implemented.

Combined with the Sora 2 social media app, OpenAI is positioning AI at the center of social platforms. This shows AI becoming not just a tool, but part of our daily lives.

If voice chat and video call features are added in the future, it could truly rival Zoom and Teams! A future where AI participates in meetings, takes minutes, organizes tasks, and provides additional information is visible! 🚀💬“

Summary

ChatGPT’s group chat feature opens new possibilities for AI assistants:

  1. Pilot in 4 Regions: Japan, New Zealand, South Korea, Taiwan
  2. GPT-5.1 Auto: Optimal model selection based on prompts
  3. Smart Conversation Flow: Understanding when to speak
  4. Diverse Use Cases: Travel planning, renovations, restaurant selection, etc.
  5. Social Platform Evolution: OpenAI’s strategic shift

This feature evolves ChatGPT from a personal AI assistant into a social tool supporting collaboration with friends and family. It will be refined based on pilot feedback and eventually rolled out globally.

With careful attention to privacy and security, all eyes are on how this new feature integrates into our daily lives. A new era where AI becomes part of social spaces is about to begin.
