Google did not unveil a product named Gemini 4 at its annual I/O developer keynote on May 19, 2026. Instead, the company announced updates within the Gemini 3.5 generation: Gemini 3.5 Flash, characterized as combining frontier reasoning with agentic task execution and outperforming Gemini 3.1 Pro on coding, agentic, and multimodal benchmarks; and Gemini Omni, a new model series accepting image, audio, video, and text inputs while producing video output grounded in real-world knowledge.
Google also introduced Gemini Spark, described as a personal AI agent designed to take autonomous actions on behalf of users, initially available to Google AI Ultra subscribers in the United States. The keynote additionally featured Android XR smart glasses developed with hardware partners and Gemini-powered updates to Gmail and Google Docs.
Pre-event speculation had centered heavily on a potential Gemini 4 release, driven in part by anonymous-sourced reporting and pre-keynote leaks. Google's naming convention at I/O stayed within the 3.5 generation. The community placed an 85% probability on a Gemini 4 unveiling; the models introduced carried different branding.
