Google announced GA for Gemini 3.1 Flash-Lite on May 7, its fastest and most cost-efficient Gemini 3 model. Priced at $0.25/M input and $1.50/M output tokens, it delivers 2.5x faster time-to-first-token and 45% faster output generation versus 2.5 Flash with equivalent or better quality. Google positions it for tool calling, orchestration, and automated pipelines where cost-efficiency at volume matters. This is the cheapest frontier-adjacent model from a major lab.
