Sam Altman releases personal AI agent. Google releases Argon AI — Does this look like any of these companies are slowing down.

OpenAI follows Meta into the red-hot market for personal agents.

Following Meta’s blockbuster release of its Muse AI agent earlier this month, OpenAI jumped into the personal agent market on Tuesday with Dots, setting the stage for what could be the next big battle in the artificial intelligence market.

At its annual DevDay developer conference, OpenAI described Dots as “always-on” agents designed to help users complete a range of tasks. Since the release of Muse three weeks ago, investors have rallied around Meta, sending the stock up 29% in September, on pace for its best month since 2013.

That level of enthusiasm underscores the power of personal agents and the promise that consumers and office workers will be able to use the technology to book travel, pay bills, respond to emails and perform many more tasks. But OpenAI’s entry, arriving soon after the launch of Muse, serves as a reminder that the AI market includes a handful of large companies all converging around the same types of products with little ability to lock in users.

Google rolls out Gemini 4 Argon, its most advanced AI model

Alphabet unveiled Gemini 4 Argon on Wednesday, its most advanced artificial intelligence model yet, offering major improvements in coding, cybersecurity, and complex professional work.

The company said the model sets a new record in real-world software engineering, ties for first in cybersecurity, and leads another benchmark measuring performance across finance, legal, and other professional tasks.

Argon is already being used internally to optimize memory at Google’s data centers, freeing up hundreds of terabytes of memory without buying additional hardware, the company said. Quantum computing researchers have also utilized the model.

Google plans to launch the new model in phases, starting with trusted cybersecurity partners while working with the U.S. government on pre-release safety evaluations.
