模型介绍

Google: Gemini 3.1 Flash Lite

Gemini 3.1 Flash Lite is Google’s GA high-efficiency multimodal model optimized for low-latency, high-volume workloads. It supports text, image, video, audio, and PDF inputs, and is designed for lightweight agentic workflows, simple data extraction, classification, summarization, and applications where responsiveness and API cost are the primary constraints.

Why It Looks Great

High-efficiency multimodal model for text, image, video, audio, and PDF understanding
Optimized for low-latency, high-volume production workloads
Supports a 1M-token context window for long prompts, document analysis, and multi-turn workflows
Up to 64K output tokens for extended responses and structured generation
Thinking levels from minimal to high for cost, latency, and quality trade-offs
Priced at half the cost of Gemini 3 Flash
Strong fit for lightweight agents, simple extraction tasks, summarization, classification, and responsive app experiences
