OpenAI held its annual DevDay on September 29th in San Francisco, with a live keynote featuring CEO Sam Altman. The company announced several updates, including Dots, an AI agent product positioned as a rival to Meta’s recently launched Muse. Unlike Muse, which is free, Dots will initially be available only to paid subscribers of ChatGPT Pro, Business Premium, and Enterprise.

OpenAI also introduced its GPT-6.1 Sol model and said ChatGPT now has 1.2 billion users per week. A new ChatGPT Pro plan priced at $500 per month was announced. The event drew protesters who gathered at the venue.

Why it matters

The announcements point to OpenAI expanding both its model lineup and its agent offerings while introducing a higher-priced subscription tier, indicating continued competition with rivals such as Meta.

Who should care

Developers and businesses using ChatGPT, particularly those on Pro, Business Premium, and Enterprise plans, along with organizations evaluating AI agents.
