Google Introduces Gemini 3.1 Flash-Lite for High-Volume AI Workloads

Google has introduced Gemini 3.1 Flash-Lite, its fastest and most cost-efficient model in the Gemini 3 series. The model is designed for developers managing large-scale workloads and is now available in preview through the Gemini API in Google AI Studio and for enterprise users via Vertex AI.

Gemini 3.1 Flash-Lite is priced at $0.25 per million input tokens and $1.50 per million output tokens. It delivers 2.5 times faster response times and a 45% increase in output speed compared to Gemini 2.5 Flash, while maintaining similar or improved quality. According to benchmark results, it achieved an Elo score of 1432 on the Arena.ai leaderboard and scored 86.9% on GPQA Diamond and 76.8% on MMMU Pro, outperforming previous-generation models.

The model includes configurable “thinking levels” in AI Studio and Vertex AI, allowing developers to adjust reasoning depth for different tasks. This feature supports both high-frequency operations like translation and content moderation, and more complex tasks such as UI generation or simulation building.

Early-access users, including companies like Latitude, Cartwheel, and Whering, have reported efficient performance and strong instruction-following capabilities. Gemini 3.1 Flash-Lite is part of Alphabet’s ongoing expansion of the Gemini 3 lineup, aimed at scaling AI capabilities across diverse use cases.
