Google unveils Gemini 3.1 Flash-Lite — a fast, low-cost LLM

Google introduced Gemini 3.1 Flash-Lite, the newest member of the Gemini 3 family designed specifically as a high-throughput, low-latency, cost-efficient engine for developer and enterprise workloads. Google positions Flash-Lite as the “fastest and most cost-efficient” model in the Gemini 3 line: a lightweight variant that aims to deliver streaming interactions, large-scale background processing, and high-frequency production tasks (for example, translation, extraction, UI generation, and large-volume classification) at a much lower price point than its Pro counterparts

Gemini 3.1 Flash is Coming Soon: What it is

Gemini 3.1 Flash—the ultra-low-latency, image-capable member of the Gemini 3.1 family—is being rolled out across Google’s consumer and developer surfaces. Gemini 3.1 Flash builds close the gap between reasoning quality and responsiveness. For image tasks, the Flash Image variant improves on text rendering within images and maintains coherent identities for multiple characters and objects across a workflow — a common pain point for earlier image models.
