Google I/O 2026 brings Gemini 3.5 into Search, the Gemini app and video creation tools

At Google I/O 2026, Google introduced Gemini 3.5 as its latest family of AI models, making it the default for the Gemini app and AI Mode on Google Search while expanding its agentic features across consumer, developer and enterprise use cases.

The model is now available globally and serves as the default for the Gemini app and AI Mode on Google Search. Google described Gemini 3.5 as combining frontier intelligence with action, with the model designed to support more capable AI agents and long-horizon tasks.

Gemini 3.5 targets longer agentic tasks

For enterprises and developers, Gemini 3.5 is positioned around a balance of speed, performance and cost. Google said the model can help users complete long-horizon agentic tasks in a fraction of the time and often at less than half the cost of other frontier models.

The company cited use cases including developing new applications, maintaining codebases and preparing financial documents. The focus places Gemini 3.5 within a broader move towards AI systems that can complete multi-step work, rather than respond only to individual prompts.

Google CEO Sundar Pichai said the company is extending agentic capabilities beyond developers and enterprises. “Gemini 3.5 and Antigravity are unlocking a new world of agents and agentic capabilities. We’ve been bringing agents to developers and enterprises for a while. Now we are super focused on bringing the power of agents, safely and securely, to consumers so that it works for everyone.”

Gemini app gets redesigned around conversational use

Google has also redesigned the Gemini app with a new design language called Neural Expressive. The updated experience includes fluid animations, vibrant colours, overhauled fonts and haptic feedback across web, Android and iOS.

The redesign brings Gemini Live more closely into the app experience, allowing users to move between typed questions and free-flowing conversations. Google said responses will also become more visual and easier to follow through images, timelines, narrated videos and interactive images.

For users in the US, the Gemini app will include Gemini Spark, an upcoming personal AI agent that runs around the clock and helps users navigate their digital lives under their direction. It will also include Daily Brief, a personalised digest that uses connected apps to organise the day ahead around user goals and suggest next steps.

Search adds AI agents and follow-up conversations

Google is also changing the Search box to support more detailed questions. The updated Search box dynamically expands so users can describe what they need, while AI-powered suggestions help them form questions beyond standard autocomplete.

Users will also be able to continue a conversation with Search by asking follow-up questions directly from an AI Overview. The update moves Search further towards an interactive format, where users can refine queries after seeing an initial response.

Google is also introducing information agents in Search. These agents will look across the web and real-time data to monitor changes related to a specific question, then create synthesised updates with the ability to take action. Agentic booking capabilities are also being expanded to new tasks, including local experiences and services.

Gemini Omni brings conversational editing to video

Google also introduced Gemini Omni, a new model that can combine images, audio, video and text as inputs to generate videos grounded in Gemini’s real-world knowledge. Users can also edit videos through conversation.

The first model in the family, Gemini Omni Flash, is rolling out to all Google AI Plus, Pro and Ultra subscribers globally through the Gemini app and Google Flow. It is also rolling out at no cost to users on YouTube Shorts and the YouTube Create App starting this week.
