AI price changes
Labs publish today's price. None of them publish yesterday's, so we write ours down every fifteen minutes and show you what moved.

What's changed
Nothing has moved yet.
We started writing down prices on 2026-09-05, and every model we watch still costs what it did then. That is the boring answer, and it's the true one.
Why this page is short
It only knows what it has seen. We can't tell you what GPT-5 cost last year, because we weren't watching last year, and copying a number out of an old blog post would be guessing with extra steps.
So the record starts on 2026-09-05 and gets more useful every month it runs. A model that appears here with "added to the list" is new to our catalogue, which usually means it's new.
What counts as a change
A move in the published list price per million tokens, either half of it. We don't track caching discounts, batch rates or anything you negotiated, because none of those are published and we'd be making them up.
