Frequently asked questions
How much does Gemini 2.5 Pro cost per 1M tokens?
Gemini 2.5 Pro costs $1.25 per million input tokens and $10.00 per million output tokens at Google Gemini list prices. Output is 8.0x the input rate, so the input:output ratio of your workload drives the real cost more than the headline price.
Does Gemini 2.5 Pro support prompt caching?
Yes. Cached input is billed at $0.125 per million tokens, 10x cheaper than uncached input. There is no cache-write premium, so caching is never a net loss.
What is the batch discount for Gemini 2.5 Pro?
Requests submitted through the asynchronous batch endpoint are billed at 50% off both input and output rates, bringing input to $0.625 and output to $5.00 per million tokens.
What is Gemini 2.5 Pro's context window?
1.0M tokens of context with up to 66K output tokens per request. A larger context window raises the ceiling on what you can send, not the price per token — but filling it on every request is one of the most common causes of an unexpected bill.
