Google I/O 2026 Unveils Gemini 3.5 Flash and Antigravity 2.0 for Agentic Development
Google launches Gemini 3.5 Flash and the Antigravity 2.0 ecosystem at I/O 2026, giving developers powerful new tools to build production-ready AI agents. The updates bridge the gap between simple prompts and complex, automated workflows.
Google accelerates the transition from basic prompts to actionable AI at I/O 2026 by launching Gemini 3.5 Flash. This new model outperforms the previous Gemini 3.1 Pro across nearly all benchmarks while operating four times faster than competing frontier models. This speed provides the essential foundation developers need to build effective, real-world agentic workflows.
The tech giant expands its Google Antigravity ecosystem to help developers turn ideas into production-ready applications. The highlight is Antigravity 2.0, a standalone desktop application that serves as a central hub for orchestrating multiple agents in parallel. It features dynamic subagents, scheduled background tasks, and deep integrations with Google AI Studio, Android, and Firebase.
Developers gain additional flexibility through the new Antigravity CLI for terminal-based agent creation and the Antigravity SDK for programmatic access to Google's internal agent harness. Alongside these tools, Google introduces Managed Agents in the Gemini API and native Android vibe coding in Google AI Studio to further streamline the app-building process.
