OpenAI DevDay 2026: The biggest news and announcements
It’s OpenAI’s turn in the fall tech events calendar. The company is hosting its annual DevDay on September 29th in San Francisco, and during a live keynote featuring CEO Sam Altman, it revealed several notable updates, including Dots , its AI agent product that rivals Meta’s recently-launched Muse. However, unlike Muse, which is available for free, Dots will initially be available to paid subscribers of ChatGPT Pro, Business Premium, and Enterprise. The company also revealed its GPT-6.1 Sol model, said that ChatGPT now has 1.2 billion users per week , and announced a new ChatGPT Pro plan that costs $500 per month .
DevDay is happening at a tumultuous moment for OpenAI. The AI industry has been rocked by revelations of agents hacking outside companies, including OpenAI’s own models, which breached Hugging Face earlier this year. The hacks kicked off a broader conversation about a potential AI development slowdown .
