Introducing Gemini 3.1 Flash-Lite for Scalable Intelligence

Google has unveiled the new Gemini 3.1 Flash-Lite model, which is the fastest and most cost-effective in the Gemini 3 series. It is aimed at developers working with high volumes of data.

Starting today, Gemini 3.1 Flash-Lite is available for developers in preview mode through the Gemini API in Google AI Studio, as well as for enterprises via Vertex AI.

The model offers an excellent price-to-performance ratio, costing just $0.25 per 1 million input tokens and $1.50 per 1 million output tokens. Gemini 3.1 Flash-Lite demonstrates enhanced performance at significantly lower costs compared to larger models.

According to Artificial Analysis, the new model is 2.5 times faster in providing the first response and increases output speed by 45% compared to the 2.5 Flash model, while maintaining comparable or even better quality.

The low latency makes Gemini 3.1 Flash-Lite ideal for high-frequency workflows, enabling developers to create responsive and realistic user interfaces.
