Pricing

Long-prompt tiers

Pricing changes above a prompt-size threshold. If your average request is near the boundary, the effective rate is not the headline rate.

At the calculator's starting volume, 1M input tokens and 200K output tokens with no cache hits, Gemini 2.5 Pro costs $3.25: $1.25 for input and $2.00 for output, at the prices above. Same formula as the calculator; change the volume there.
