Google $GOOGL -2.34% announced Gemini Spark, a personal AI agent that operates continuously to complete tasks on a user's behalf, at its annual I/O developer conference on Tuesday. The agent is built on Gemini 3.5 Flash, Google's latest model, and runs on Google Cloud infrastructure, meaning users do not need to keep a device active for it to function.

Google is rolling out Gemini Spark to trusted testers now, with a wider beta release planned for Google AI Ultra subscribers in the U.S. next week. AI Ultra is a subscription tier priced at $100 a month, according to The Wall Street Journal.

Gmail, Google Docs, and the broader suite of Google Workspace tools are all natively accessible to Spark without additional setup. Reaching the agent is as simple as sending a message to a designated Gmail address, and Spark uses Chrome to carry out any web-based tasks. A new Android feature called Android Halo lets mobile users keep tabs on what Spark is doing, according to TechCrunch.

"It's your personal AI agent that helps you navigate your digital life, taking action on your behalf and under your direction," Alphabet CEO Sundar Pichai told reporters during a briefing ahead of the event. "It runs on dedicated virtual machines on Google Cloud seamlessly, [so] you don't need to keep your laptop open to make sure it's running."
