Gemini 3.5 Flash is Google’s fast and efficient multimodal model, combining advanced coding, reasoning, and agentic capabilities with the speed and affordability of the Flash family. Designed for scalable AI workflows, it supports text, image, video, audio, and PDF inputs, making it ideal for coding assistants, automation, and multi-agent applications. With medium thinking effort enabled by default, Gemini 3.5 Flash delivers an optimized balance between intelligence, speed, and cost. Developers can adjust thinking levels from minimal to high to fine-tune performance for different use cases.

Model Center 会在不同服务提供商之间规范化处理请求和响应，为你统一接口。
提供兼容 OpenAI 的 Completion API：既可直接调用，也可通过 OpenAI SDK 调用，一把 key 调用全部模型。
