What the record shows
We have observed 2 changes to Gemini 2.5 Pro's rates since it entered our archive on 2025-06-23. The most recent, on 2026-01-19, left the output rate unchanged. Every change we hold for it has been downward.
Against the 40 models we price, it is the 28th cheapest for retrieval-shaped work, which reads a great deal and writes little, and the 31st cheapest for content-shaped work, which does the reverse. The two are far apart, and that is the useful part: Gemini 2.5 Pro is relatively better value the more your workload reads and the less it writes. A single position in a table sorted one way would have told you the opposite of the truth for the other kind of work.
It charges 8.0 times more for output than for input, against a median of 5.0 times across the set. That is wider than most, so the length of the answers you ask for matters more here than it does elsewhere.
Inside Google's own lineup it is the 6th cheapest of the 7 models we track on this workload, so 5 cheaper and 1 more expensive option sits on the same account behind the same key.
One other model we price charges exactly $1.25 in and $10.00 out: GPT 5 Chat. Where a rate ties exactly, price has stopped being the deciding factor and this site has nothing further to tell you: that choice comes down to your own evaluations, which we do not run and do not score.
Cached input reads at $0.125 against a standard input rate of $1.25, a 90% discount on the part of your prompt that repeats.
It accepts image input and Google publishes a tokenisation rule for it, so a scanned page can be priced honestly: about 1,032 tokens for a US Letter page at 200 DPI, before the instructions you send with it.
Its 1.05M token context window holds roughly 786,000 words of English text in a single request, or about 1,016 scanned pages at the per-page figure above. A workload that does not fit cannot run here at any price, which is a capability limit rather than a cost one.
