What is Gemini 3.1 Flash Lite?
Gemini 3.1 Flash Lite is Google's ultra-light, next-generation Flash model, designed to be the most affordable option in the Gemini family. Despite its lightweight focus, it carries a 1,048,576-token context window, so it can still ingest very large documents and datasets, and it supports up to 65,536 output tokens per response. It is tuned for speed and high throughput, making it ideal for simple, high-volume tasks like classification, extraction, and quick summarization. Pricing is $0.35 per 1M input tokens and $2.10 per 1M output tokens, the lowest among the Gemini models offered here.
Build with Gemini 3.1 Flash Lite via YepAPI
Call the OpenAI-compatible /v1/ai/chat endpoint with your YepAPI key. The standard Chat Completions schema means you can adopt it by changing only the base URL and model name in your existing SDK. Use it for cheap, fast tasks at scale — tagging, routing, extraction, and short summaries — including over large inputs thanks to its 1M context. One key also unlocks other models plus SEO, SERP, and scraping APIs, so you can pull web content and process it cheaply through one integration.
Gemini 3.1 Flash Lite API pricing — $0.35 / $2.10 per 1M tokens
Gemini 3.1 Flash Lite costs $0.35 per 1M input tokens and $2.10 per 1M output tokens, the most affordable Gemini rate available here. Combined with a 1M-token context, that makes it economical to run large-input tasks at high volume. Per-token billing means simple jobs cost a fraction of a cent each, so it scales comfortably across millions of lightweight requests.

When the task is simple but the volume is enormous, Gemini 3.1 Flash Lite is a strong, low-cost default.
