Chat Assistants: ChatGPT, Gemini, Claude, Meta AI — 2026-09-27
The big story this week is Microsoft's strategic retreat: on September 25 it merged its consumer and workplace Copilots into a single workplace-focused "super app," ceding the consumer chatbot race to OpenAI, Google and Meta. Meanwhile, Comscore's Q2 2026 report shows ChatGPT's lead in US prompt volume eroding to Gemini and Claude, and ChatGPT suffered a fresh outage on September 25.
Chat Assistants: ChatGPT, Gemini, Claude, Meta AI — 2026-09-27
Top developments
Microsoft merges Copilots into an all-in-one workplace "super app"
On Friday, September 25, Microsoft announced a new Copilot that merges the consumer and workplace versions of the assistant into one product aimed at corporate customers, combining AI chat, coding and Autopilot agents. The Verge reports Microsoft believes the app can be "as influential as Office." A per-user monthly license covers everyday chat and Copilot in Word, Excel, PowerPoint, Outlook and Teams, while heavier agent work (Cowork, Code, Autopilot) and frontier models like OpenAI's Astra and Anthropic's Claude Fable are billed on usage.
The move is widely read as a retreat: the Los Angeles Times reports Microsoft is "ceding the crowded market for personal chatbots to OpenAI, Alphabet's Google and, now, Meta Platforms."
ChatGPT's US prompt share falls 20 points as Gemini and Claude gain
Comscore's Q2 2026 AI Intelligence Report, released around September 22, shows consumers rapidly diversifying their assistant usage: ChatGPT's share of total AI prompt volume fell from 70% to 50%, while Gemini reached 30% and Claude 11%. Sponsored ads appeared in 47% of ChatGPT video-game chats by June, and Google's AI Overviews covered 39.4% of desktop searches. Comscore also found assistant visits reached 35% of desktop and 29% of mobile users in June.
Fresh ChatGPT outage hits on September 25
Users reported OpenAI's ChatGPT and Codex failing this week with an "Unexpected status 401" error, Hindustan Times reported on September 25. It follows a pattern of repeated cross-provider outages this autumn (though the major multi-provider outage was on September 3, outside this window). Reliability remains a differentiator consumers actually notice.
Meta pushes Muse AI agent
CNN Business on September 23 tested Meta's new Muse app, whose AI agents can carry out tasks on a user's behalf — signal that Meta is leaning into agentic assistants beyond its Meta AI chat product.
Local view
Spanish-language media focused squarely on the Microsoft retreat. Chile's BioBioChile framed it under the headline "Microsoft se rinde en la carrera con ChatGPT y Gemini: dejará Copilot sólo para empresas" ("Microsoft gives up the race with ChatGPT and Gemini: Copilot will be for companies only"), recalling the assistant's launch barely a year earlier under the slogan "your everyday AI companion."
Context & numbers
- ChatGPT: ~1 billion weekly active users; Gemini app surpassed 1 billion monthly users; Copilot ~420 million (with over 30 million
- US prompt volume share (Comscore Q2 2026): ChatGPT 50%, Gemini 30%, Claude 11%
- Subscription pricing: ChatGPT Plus $20/mo, Copilot Pro $20/mo, Google AI Pro $19.99/mo
On the radar
- How OpenAI and Anthropic model usage inside the new Copilot super app (Astra, Claude Fable) is billed per-usage — watch for enterprise pricing fallout.
- Meta's Muse agent expansion beyond initial users, per CNN's early hands-on.
- Follow-up Comscore quarters to see whether ChatGPT's prompt-share slide below 70%→50% continues.
