Google I/O 2026: New AI Tools for Developers

Google is shifting to an 'agent-first' approach for app development. This means AI agents will help plan, write, and test code automatically.
By Newsroom | Technology, Artificial Intelligence |

MOUNTAIN VIEW, CA - Google has declared a shift towards an "agent-first" development paradigm at its I/O 2026 conference, rolling out a suite of tools aimed at creating applications driven by autonomous agents. The company introduced Google Antigravity 2.0, an updated development platform that includes a desktop application and an SDK. This platform is designed to allow developers to move from conceptualizing ideas to deploying production-ready applications. Key features include 'Managed Agents' within the Gemini API, providing developers access to the same agent technology powering Google's internal products, and expanded integrations with Google Workspace for native API calls within applications.

The central theme is the evolution of AI tools from mere assistance in writing code to agents capable of complex actions and autonomous development. This includes capabilities for agents to plan architecture, write multi-file features, and conduct end-to-end testing.

The announcement also featured new AI models, Gemini Omni and Gemini 3.5 Flash. Gemini Omni is presented as a significant advancement in understanding, multimodality, and editing, capable of generating content from various inputs, including video. Gemini 3.5 Flash is positioned as the first model in a new series that combines advanced intelligence with actionable capabilities, intended to replace Gemini 3.1 Flash as the default model on the Gemini app. Google DeepMind CEO Demis Hassabis announced Gemini Omni, with paid subscribers gaining access to it starting today. On performance metrics, Gemini 3.5 Flash reportedly surpasses the older Gemini 3.1 Pro model in coding and agentic tasks.

Google AI Studio is also seeing enhancements, with mobile integration and an expansion of its "vibe coding" capabilities. Developers can use AI Studio to prototype and then export code to Google Antigravity for scaling into production. This includes features that facilitate the transition from rapid exploration within AI Studio to autonomous development within Antigravity, allowing for the export of projects and local deployment.

The "agentic era" was framed as the focus of the developer conference, highlighting tools designed to automate complex workflows and streamline the creation of AI-ready applications. Developers using the older Gemini CLI tool are being advised to plan their migration to the new tools. Gemini Spark, described as Google’s most ambitious consumer AI product to date, is also part of this push – a persistent, always-on AI agent designed to manage tasks across a user's Google ecosystem.

Background and Context

Google's I/O 2026, held on May 19-20, showcased updates across AI, Android, Chrome, and Cloud. The keynote address specifically highlighted the "agentic era" of development. The strategy appears to integrate these new agentic capabilities across Google's product suite, with mentions of Information agents in Search, Gemini Spark, Daily Brief in the Gemini app, and Universal Cart for shopping. Extensions into products like Google Pics, intelligent eyewear, and Ask YouTube are also indicated.

The development platform Google Antigravity is presented as an "agent-first development platform." The Antigravity SDK is intended to provide programmatic access to the underlying agent harness used in Google's own products. Developers can use this SDK to build custom agents and run them on their local servers. For cloud-based development pipelines, 'Managed Agents' within the Gemini API are being offered, allowing for sandboxed execution.

The expanded reach of Google AI Studio includes a mobile application, alongside automated Android app publishing features. The Antigravity 2.0 desktop app is described as a "dedicated central station for automation." Integration possibilities with Google AI Studio, Android, and Firebase are highlighted, with Google Cloud customers also being able to connect to Antigravity for project building.

AI agents are noted to operate via SSH, CLI, and APIs, with a suggestion that GUI-based shared hosting may be difficult for them to use.
