Google Launches Gemini 3.1 FlashLite AI Model

Google announced the launch of Gemini 3.1 FlashLite on March 3, 2026, introducing what the company describes as its fastest and most cost-efficient artificial intelligence model in the Gemini 3 series. Designed for high-volume developer workloads, the model became available in preview through the Gemini API in Google AI Studio and Vertex AI for enterprise users, enabling early testing in production environments.

The new model targets applications requiring rapid responses and scalability, such as real-time content moderation, large-scale translation, and automated data processing. Google engineers optimized Gemini 3.1 FlashLite for efficiency, incorporating adjustable thinking levels that allow developers to control the depth of reasoning applied to tasks. This feature helps balance latency, cost, and output quality in high-frequency operations. For instance, users can reduce reasoning for simple queries to minimize token usage or increase it for more complex instructions, like generating user interfaces or simulations.

Pricing underscores the model's focus on affordability. It costs $0.25 per million input tokens and $1.50 per million output tokens, significantly lower than...
