    How to read Gemini 3.1 Flash Lite's pricing

    Two numbers decide most of the bill: $0.25/1M for input (everything you send — prompt, context, attachments) and $1.50/1M for output (everything it generates, including hidden reasoning tokens). Output is priced 6.0× the input rate here, so the shape of your workload — how much it reads versus writes — matters as much as the headline figure. This is the provider's first-party list price, reconciled against the routed market each run.
