Google Launches Gemini Spark to Execute Long-Running Background Tasks

Gemini Spark is Google's new 24/7 personal AI agent designed to operate autonomously. Unlike standard conversational AI, Spark uses the Antigravity framework to handle long-running tasks. It employs Gemini 3.5 to reason through complex goals, following the general availability of Gemini 3.5 Flash.

This release marks a shift from reactive assistants to proactive agents that do not require constant human supervision. It extends the recently expanded Antigravity developer ecosystem and mirrors the infrastructure introduced with the Gemini Enterprise Agent Platform. By bringing these capabilities to a personal agent, Google is competing directly with Meta's Muse Spark reasoning model.

You can direct the agent to perform background workflows that previously required manual oversight, such as navigating digital accounts or managing multi-step tasks. The system acts under your direction while maintaining a persistent presence. Access is currently rolling out as part of the broader Gemini ecosystem, supported by new Gemini Ultra pricing tiers.

Gemini Spark is a personal AI agent from Google designed to help you navigate your digital life 24/7. Unlike standard chatbots that only respond to prompts, this agent can take action on your behalf and under your direction. It is built to handle long-running tasks that execute in the background.

Gemini Spark is powered by the Gemini 3.5 model and is built on the Antigravity framework.
