OpenAI launched Dots, its new "always-on" personal AI agent, at its annual DevDay developer conference Tuesday, plunging the company into a fast-growing market that Meta opened just three weeks ago with its Muse agent.

The company described Dots as agents built to help users complete a range of tasks, from booking travel to paying bills to responding to emails. The announcement positions OpenAI directly against Meta, whose Muse release sent its stock up 29% in September, putting it on pace for its best month since 2013.

The stakes are high because personal agents represent what many in the industry see as the next major phase of artificial intelligence. The technology promises to move beyond chatbots that answer questions and into software that takes action on a user's behalf.

"I think what we are watching is an inevitable evolution of the technology," said John Waldmann, CEO of HR tech startup Homebase and a user of various AI agent tools. "It's probably no surprise that it's all happening around the same time."

OpenAI is not alone in the race. Google markets its Gemini Spark offering as "your 24/7 personal AI agent," and Apple is pushing a redesigned Siri it calls "a profoundly more capable and personal assistant."

The convergence raises a question investors and analysts are starting to ask: with so many similar products arriving at once, can any single company lock in users? The major players are building toward the same capabilities, and switching costs for consumers remain low.

Startups are crowding in as well. AI assistant company Instinct announced Monday that it raised $1 billion from investors including Sequoia at a $10 billion valuation. Another startup, Town, is also developing agent technology.

Meta's stock surge shows how much Wall Street is betting on the category. Investors have rewarded the first major player to ship a consumer-ready agent, and OpenAI's entry less than a month later signals the company does not intend to cede the space.

Whether users will pay for these agents is unresolved. Most of the products so far are tied to existing subscriptions or bundled with other services, and none has demonstrated a clear path to standalone revenue.

OpenAI did not announce pricing details for Dots at the conference. The company has not said when the product will be broadly available.
