Gemini 3.8 Flash is on a promotional price that doubles on 1 January 2027
Google is charging a promotional $0.75 per million input tokens for Gemini 3.8 Flash until the end of 2026, after which the published price doubles.
What happened
Published here
Google's Gemini API pricing page prices Gemini 3.8 Flash at $0.75 per million input tokens and $3.75 per million output tokens, and prints the end of that price on the same line: "$0.75 through December 31, 2026. $1.50 starting January 1, 2027", with output moving to $7.50 and caching from $0.075 to $0.15. We read the page on 5 September 2026 and recorded the promotional figures as the current price with the scheduled ones in the row's note. (Gemini API pricing, read 5 September 2026)

What it means for you
This is a price with an expiry date on it, and the expiry is a doubling. If you are choosing a model now for work that runs into next year, the figure to plan against is $1.50 rather than $0.75, and the comparison you make today against other vendors is a comparison against a number that has four months to live. We record both figures with the date the page was read, so when January arrives the change will be a logged event rather than a surprise on an invoice. Google also publishes no second official page confirming this price, which is noted on the row.
In more detail
A promotional price is not a lie, but it is a shape of honesty worth naming. The figure is real, the end date is published, and both are on the same page. What the page does not do is show you the comparison after the change, and that is the comparison that matters if the thing you are building will still be running in February.
Our row carries both numbers for that reason. The price column holds what Google charges today, because that is what a bill would say today, and the note holds the scheduled figures with the vendor’s own wording. When the promotion ends, the row moves and the move is dated against this reading rather than against nothing.
