ChatGPT Group Chats Roll Out Worldwide
OpenAI is rolling out group chats for ChatGPT to enable collaboration within a single conversation thread, separated from users’ private chats. The pilot starts in Japan, New Zealand, South Korea, and Taiwan and will be accessible on Web and mobile to Free, Go, Plus, and Pro users with the latest apps. Groups can be named, invite up to 20 participants via a link, and participants must set up profiles (name, photo, username). ChatGPT can join groups by being mentioned to provide information or inspiration, while the AI can also act passively when appropriate. Custom Instructions let groups tailor responses. Group chats use the GPT-5.1 Auto model, offering Instant or Thinking modes, emoji reactions, and the ability to reference user profile pictures or include documents. OpenAI notes broader regional expansion and mentions an upcoming Figma integration for Business/Enterprise/Edu plans; parental controls block content for under-18s, and group chats appear in a separate sidebar tab.
ChatGPT returns to WhatsApp in Europe
The EU has ordered Meta to allow third‑party large language model (LLM) chatbots back onto WhatsApp in the European Economic Area after Meta had previously restricted non‑Meta chatbots like ChatGPT and Copilot in favor of Meta AI. The interim measures and ongoing antitrust scrutiny (a cartel/competition probe opened in December 2025) compelled Meta to re‑enable access for competitors across the 27 EU member states plus Iceland, Liechtenstein and Norway. OpenAI has signalled ChatGPT’s availability on WhatsApp (and notes availability on Kakao in South Korea and Viber in supported markets). On WhatsApp, ChatGPT supports text chat, voice messages, multiple languages, image upload and image generation features. The publisher tested availability and provides instructions for locating the official ChatGPT account on WhatsApp.
ChatGPT Mobile App Gets Voice-Based Agentic Features
OpenAI announced on Wednesday that it is bringing voice-based agentic features to the ChatGPT mobile app, allowing Plus and Pro users to trigger workflows such as drafting documents, summarizing emails, or creating presentations via the Work tab. These subscribers can also build sites, use a cloud browser, and access other areas like finances. Free and Go users will get access to plugins and connected apps. The feature includes richer text output in voice conversations, easy switching between text and voice, and the ability to start a conversation on mobile and resume on desktop. This rollout extends the voice capabilities previously introduced with the GPT-Live model to mobile, following its integration with the desktop app in July.
