API Overview

Gemini 3.5 is a new-generation AI model series unveiled by Google at the 2026 I/O Developer Conference, marking a pivotal shift in Google’s core AI strategy—from “intelligent interaction” to fully action-oriented, deep execution. This series of models is specifically designed for complex, multi-step business workflows. By seamlessly integrating cutting-edge intelligence with powerful tool-call capabilities, it aims to deliver productivity solutions that surpass previous offerings for both individual users and enterprise markets.

Core Capabilities

Natively Action-Oriented Intelligent Architecture: The core design philosophy of Gemini 3.5 lies in execution. Through highly optimized agent workflows, the model can autonomously break down complex instructions, schedule and execute long-term tasks across multiple applications, truly becoming an “executor” rather than merely a “consultant.”

Extreme Performance and Deployment Strategy: Among this series, Gemini 3.5 Flash stands out particularly. It not only surpasses the previous 3.1 Pro model in benchmark tests for coding efficiency and complex agent tasks but also, thanks to its exceptional cost control and processing speed, has become the core driving force behind Google Search and Gemini applications today. This high energy-efficiency ratio makes long-term, cross-application AI agent tasks feasible.

Cross-Generation Leap in Logical Intelligence: Gemini 3.5 demonstrates remarkable stability in complex logical reasoning and fine-grained task understanding, enabling it to precisely meet the demands of developers and enterprise users while competing head-to-head with other top-tier large models in the industry.

Seamless Integration and Ecosystem Collaboration: The Gemini 3.5 series does not exist in isolation—it is deeply integrated into Google’s comprehensive global product and technology stack. From AI modes in the search bar to enterprise-level cloud deployments, this series provides a unified, high-performance foundation, ensuring that users across billions of Google products enjoy a consistent and top-notch intelligent experience.
