Gemini 3.1 Flash Lite endpoint guide

How to interpret the Cheapest Gemini 3.1 Flash Lite Inference Providers

6 of 6 Gemini 3.1 Flash Lite endpoints currently have the published data required for this ranking. Google Vertex leads at $0.333333 / 1M via google-vertex/global/flex. The table keeps unranked routes visible so missing measurements do not look like missing provider availability.

How estimated token cost is ranked

The cheapest ranking uses a 1,000-input/500-output-token ratio and reports the blended result per 1 million total tokens. Because providers can price input and output differently, a workload with a different token ratio may produce a different order.

Compare Google Vertex with the next option

Google AI Studio currently ranks second at $0.333333 / 1M. Compare that gap with input and output price, response-start time, output speed, 30-minute uptime, context length, and the exact route before deciding whether first place is meaningful for your workload.

Use the route, not only the provider name

Gemini 3.1 Flash Lite has 6 published provider options, and performance data is matched to each exact OpenRouter routing tag. Different quantization, context, regional deployment, or provider configuration can change price and behavior even when the underlying model name is identical.
