Google introduced the Gemini 3.1 Flash-Lite artificial intelligence (AI) model on Thursday. Calling it the fastest and the most cost-efficient AI model in the Gemini 3 series, the Mountain View-based tech giant said it is designed for high-volume developer workloads. The model is currently not available to end users and has been reserved for developers and enterprises via specific channels. The company also claimed that the model's output speed is higher than that of the 2.5 series. Notably, the Gemini 3.1 Flash-Lite is currently only available in preview.
