Google used its annual I/O keynote on May 19 to announce the Gemini 3.5 model family and a new persistent AI agent called Gemini Spark. The announcements, made at Shoreline Amphitheatre in Mountain View, mark Google's clearest signal yet that it is shifting from AI that responds to AI that acts.
Google introduced Gemini 3.5 Flash, the first in the new model family, designed to combine frontier intelligence with action capabilities. The company also unveiled Gemini Omni, a new AI model built for cinematic video generation and editing using text prompts, images, and video clips, and Gemini Spark, a proactive AI agent that can automate workflows and continue running tasks in the background.

Google made Gemini 3.5 Flash available immediately and rolled it into consumer and developer surfaces. Gemini 3.5 Pro, the heavier-weight version, is being used internally but will not be broadly available until next month - a delay that reportedly drew audible groans from the live audience.

What Gemini Spark Actually Does
Gemini Spark is positioned as a 24/7 personal agent for enterprise and Workspace customers. It is designed to delegate complex work, teach the agent new skills, and execute multi-step work on behalf of users. The system requires explicit approval for high-risk actions like sending emails and proactively sends critical updates. It connects to existing Gemini Enterprise connectors including Microsoft SharePoint, OneDrive, and ServiceNow. Google Cloud
This is the distinction that matters for business leaders. AI assistants have been reactive, answering questions when asked. Gemini Spark is designed to keep working after you close your laptop. For operations leaders and executives managing high volumes of information daily, that shift has real implications for how work gets structured.
CEO Sundar Pichai framed the event around what he called the "agentic Gemini era," stating the company is focused on showing users the value in the products they use every day. Google also revealed the Gemini app has now crossed 900 million monthly active users, more than doubling from 400 million the prior year. eWEEK
Search and YouTube Get Overhauled
Google announced information agents in Search - AI systems users can set up to continuously monitor topics and return useful updates or actions in the background. Pichai described them as "personalized AI agents you can set up to work in the background, 24/7, to find what you need at exactly the right moment." eWEEK
A new feature called Ask YouTube is being tested to help users navigate videos more efficiently by surfacing relevant clips and jumping to the most useful sections. Google said it will launch more broadly in the US this summer. eWEEK
What Businesses Should Take Away
Four years of watching executives implement AI has shown me one consistent pattern: the tools that actually change workflows are the ones that reduce the number of tabs you need open, not the ones that add another one. Gemini Spark is Google's bet that a persistent agent embedded in Workspace is more valuable than a standalone AI product.
Whether it delivers depends entirely on execution. The promise is significant. Gemini Spark rolls out first to Google AI Ultra subscribers in the US. Sessions and developer recordings from I/O 2026 go on demand at io.google starting May 21.
