Google CEO Sundar Pichai opened I/O 2026 by declaring an "agentic Gemini era," unveiling a 24/7 personal AI agent, a new flagship model, and a multimodal system.
Pichai Unveils Spark, Gemini 3.5 Flash
Alphabet CEO Sundar Pichai told developers in Mountain View on Tuesday that Google is processing more than 3.2 quadrillion tokens a month across its surfaces, a sevenfold jump from a year ago.
The keynote centered on Gemini Spark, a general-purpose agent that runs on dedicated virtual machines in Google Cloud and acts on a user's behalf without keeping a laptop open.
Spark is powered by Gemini 3.5 Flash and the Antigravity harness. Rollout begins this week to trusted testers, with a beta arriving for Google AI Ultra subscribers in the U.S. next week.
Pichai also introduced Gemini 3.5 Flash, now the default model in the Gemini app and AI Mode in Search globally. The company says it beats its own 3.1 Pro on coding and agentic benchmarks while running roughly four times faster than rival frontier models at as little as one-third the price.
A new world model called Gemini Omni generates outputs across modalities, launching first in video through Flow, YouTube Shorts, and the Gemini app.

Analysts See Cost, Competitive Pressure
The pricing posture drew attention from enterprise analysts. Bradley Shimmin of Futurum Group pointed to "token anxiety" inside large companies, arguing that Google, Anthropic and others now face real pressure to deliver cheaper agentic options as workloads scale.
Svetlana Sicular at Gartner offered a more skeptical read, calling the I/O reveal a response to rivals rather than a clean step ahead. "Competition is overheated," she said.
There is also a safety overhang. Google is currently defending a lawsuit tied to a user who died by suicide after nearly carrying out a mass casualty attack following weeks of Gemini chats, and TechCrunch noted the stakes rise sharply as autonomous agents reach consumers. The company says 3.5 Flash includes strengthened cyber and CBRN safeguards.
I/O 2026 Versus Last Year
Last year's I/O focused on Gemini 2.5 Pro, Veo 3 and the U.S. launch of AI Mode in Search. The Gemini app counted 400 million monthly active users at that point.
Twelve months later, the same app has surpassed 900 million monthly users and AI Mode crossed 1 billion. Capital spending guidance has climbed from $31 billion in 2022 to a projected $180 billion to $190 billion this year, much of it directed at the new TPU 8t and 8i chips.
