Google unveils Gemini 3.5 Flash, a multimodal model called Gemini Omni, and a cloud-based personal agent named Gemini Spark that runs 24/7

Google released Gemini 3.5 Flash, which beats the roughly four-month-old Gemini 3.1 Pro on nearly every benchmark. An optimized version running on Google's Antigravity platform is twelve times faster than the base Flash model, according to the company. Costs come in at roughly a third to half of comparable models.

Gemini Spark is a personal agent that runs on dedicated virtual machines in Google Cloud and stays available 24/7, continuing to work in the background even when the user's device is off. It integrates with Gmail, Docs, and other Workspace products at launch, with MCP connections to third-party services coming in the next few weeks.

Gemini Omni is Google's new multimodal model designed to produce any output from any input, with video shipping first. Unlike Veo, which is a pure text-to-video model, Omni is built on the Gemini architecture and trained as multimodal from the ground up. Users can upload their own videos, swap out characters, or change the style.

Spark rolls out this week to select testers and next week as a beta for Ultra subscribers in the US. Google is introducing a new Ultra plan at $100 per month and dropping the previous top-tier Ultra plan from $250 to $200. Monthly Gemini app users grew from 400 million a year ago to over 900 million.
