Google Unveils Gemini 3.5, Gemini Spark Agent and Omni Video Model at Google I/O 2026

Google made a wave of major AI announcements at its annual Google I/O developer conference on Tuesday. The search giant rolled out its latest version of Gemini and a new artificial intelligence model designed to simulate the physical world, racing to keep pace in model development while providing more agentic services to its massive user base. Gemini 3.5 Flash is a general-purpose frontier model that surpasses Gemini 3.1 Pro on coding, agentic, and multimodal benchmarks, running at four times the output speed of comparable frontier models. On the agentic AI front, Google announced Gemini Spark, a new general-purpose AI agent that can reason across information in connected apps. Gemini Spark is in beta and will be available first to trusted testers and Google AI Ultra subscribers starting next week. The new AI video model Gemini Omni combines Gemini with Google's generative media models to create outputs grounded in knowledge. Google AI Ultra now starts at $100 per month, down from $250. The Gemini app now has 900 million monthly active users, roughly doubling from 400 million a year ago.
