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 .

Sam Altman says OpenAI won’t go public until its models are safe

For months, people have wondered when OpenAI will go public. CEO Sam Altman says it won’t happen until the company can make better promises about model safety, with no firm timeline in sight. “We intend to continue with AI progress … but as the models have had this surge forward in capability, and we see more of that ahead of us, we have got to be able to make confident safety claims,” Altman said Tuesday during a Q&A with reporters after his DevDay keynote. At the same time, he said, waiting too long for an IPO would be “bad for the world.”

Altman’s comments come after months of controversy about whether or not OpenAI and its rivals can control their own creations. In July, news broke that an unreleased OpenAI model had hacked into a rival AI lab, Hugging Face, without OpenAI’s knowledge. More cybersecurity incidents soon came to light at OpenAI, Anthropic, Meta, and Google. A high-profile resignation letter from an Anthropic employee sparked a public discussion about how risky these systems are for society at large. OpenAI, alongside its rivals, called for regulation and “pacing the frontier.” And earlier this month, Altman said in an interview that the company would likely not go public this year.

OpenAI plans to bring Dots to consumers, too.

Right now, the new AI agents are only available for Pro, Business Premium, and Enterprise ChatGPT subscribers, but OpenAI CFO Sarah Friar tells CNBC that “our vision is to bring this to our whole consumer base as well.”

ChatGPT now has 1.2 billion weekly users, OpenAI says.

That’s up from the 1 billion weekly users milestone ChatGPT surpassed in July .

OpenAI is adding a $500 / month ChatGPT Pro tier.

The new plan includes the company’s highest usage limits and access to its Ultrafast mode , which allows GPT-6 Astra to deliver faster responses across its services, including ChatGPT Work and Codex. At the same time, OpenAI reopened its $200 / month tier with new usage limits.

OpenAI launches Dots, its Muse competitor

OpenAI is responding to Meta’s buzzy Muse AI with agentic helpers of its own: Dots. During its DevDay keynote on Tuesday, OpenAI announced that Dots will serve as always-on AI assistants that can “do nearly anything” across connected apps in the background while learning your preferences over time.

The company’s capable GPT-6 Astra model powers Dots, which use their own cloud computer to access a web browser and more than 4,000 supported apps. You can interact with a Dot through a text-message-like interface that’s similar to the one offered by Muse , as well as hop on a voice call with it from ChatGPT on the web, desktop, or mobile. Dots can also connect to Microsoft Teams and Slack, where they will carry over the context from your sessions on other apps and devices. It will soon be able to talk to you over text message as well.

On Tuesday, OpenAI’s annual DevDay event began with protests, flyers, and chants. “Sam Altman, get off it, put people over profit,” said a group of protesters marching in a circle in front of a series of signs that spelled out “PEOPLE OVER PROFIT.”

More than a dozen organizations came together to sponsor a rally outside the entrance to the event venue at San Francisco’s Fort Mason, including Bay Resistance, Tech Workers Coalition, Service Employees International Union, San Francisco Rising, and the San Francisco Labor Council. A large orange sign read “Drop the ICE contract.” Multiple people dressed in cardboard robot costumes waved cardboard scythes around. Signs read “No killer robots for ICE,” “People over AI,” “Where is your moral codex?” and “No climate destruction.”
