Google DeepMind announced Gemini 3.5 at I/O 2026, describing it as a model series that combines cutting-edge intelligence with practical action-taking abilities. The release marks a shift toward agentic AI that can reason, plan, and execute tasks.
The Gemini 3.5 family includes multiple model sizes optimized for different use cases, from on-device inference to cloud-scale deployments. Key improvements include enhanced multimodal understanding, longer context windows, and native tool-use capabilities.
CTO Koray Kavukcuoglu and Chief Scientist Jeff Dean co-authored the announcement, emphasizing that the models are designed to bridge the gap between raw intelligence and real-world utility. Developers can access Gemini 3.5 through Google AI Studio and Vertex AI.
