We expect the major announcement to be ChatGPT’s response to SpaceXAI’s Grok Bot and Meta’s Muse, building on existing AI agent tools with broader consumer appeal. 10am PT, on the dot. pic.twitter.com/0v1H8RPF2i— OpenAI (@OpenAI) September 29, 2026 OpenAI already has similar features under the ChatGPT Work umbrella, although the presentation isn’t as simple as Muse and Grok Bot. Anyway, you can watch the livestream event at the top of the hour.
