Gemini 2.5 Flash pricing and token costs
Gemini 2.5 Flash is a Google model with a 1,000,000-token context window. Rates below are per million tokens, and are the ones in effect today.
In practice
Its output-to-input ratio is 8.3 to 1, the steepest in this catalogue, which makes it unusually sensitive to answer length: a long prompt is cheap here, a long response is not. The $0.30 input rate covers text, image and video — audio input is priced separately at $1.00 and is outside what this calculator measures, since it prices pasted text and nothing else. The full 1,000,000-token window is flat-rated with no tier.
