Google Launches Gemini 3.5 Flash — Agentic Model Built to Execute Complex Tasks

Google launched Gemini 3.5 Flash at Google I/O 2026, describing it as its most capable coding and agentic AI model to date. The model is designed to autonomously execute complex tasks and build software from scratch, signaling Google’s shift from chatbot-centric AI toward agent-native architectures. Gemini 3.5 Flash is available via the API as of today. The launch positions Google directly against Anthropic’s Claude and OpenAI’s GPT-5 series in the agentic coding and autonomous task execution market.
