According to Google, unlike text-to-video AI models, Gemini Omni is multi-modal in both input and output. Users can input text, audio, images, and video into the model when crafting their prompt and, utilizing Gemini's "real-world knowledge," Omni will generate realistic and scientifically accurate content.
Gemini Omni Flash rolls out today to paid Google AI Plus, Pro, and Ultra subscribers within the Gemini app and Google Flow. Gemini Omni Flash will also launch in YouTube Shorts and the YouTube Create app at no cost to users later this week.
Gemini Spark
Gemini Spark is easily the most ambitious product revealed at I/O. Google is calling Spark "your personal AI agent" and integrates with Google's suite of products, and eventually with more than 30 third-party tools via MCP, such as Adobe, Dropbox, and Uber.
Acting as an AI agent, Spark can pull together relevant emails from your inbox and files from Docs in order to craft an update for your boss.
Notably, Spark runs entirely within the cloud and doesn't require any hardware.
Google AI Ultra subscribers in the U.S. will see Gemini Spark roll out inside Gmail and Chat in the next week.

Finally, the Gemini app is getting a new design language, which Google calls Neural Expressive. The new design language includes more fluid animations, haptic feedback, and vibrant colors, per Google. Neural Expressive also integrates the Gemini Live voice experience into the core UI, meaning users no longer have to switch back and forth.
Google says it's rolling out globally on Gemini's desktop, Android, and iOS apps.
