Cost Per Gen is a neutral pricing index for AI media generation — video, image, and voice today, music next. It exists because nobody publishes what a generation actually costs, in comparable units, across every channel that sells the same model.
About
Disclosure
This site is operated by Downshift, which also operates FairStack — an API that resells access to many of the models indexed here. That affiliation is why this index exists at all: running an AI-media API means auditing what 400+ models actually cost, every week, as an operational necessity. This index publishes the normalized view of that work.
- FairStack appears in the index as a normal provider row, tagged "same operator."
- FairStack is never default-sorted to the top, never editorially recommended, and never given a sponsored slot.
- The "cheapest" highlight is computed from the numbers, never assigned.
- Affiliate programs (when live) route via
/go/links markedrel="sponsored"and never affect sort order.
What this index is not
Not a quality benchmark — Artificial Analysis owns that, and we link out rather than compete. Not an LLM/token price tracker — Price Per Token owns that. Not an affiliate blog — every recommendation on this site is a number with a source and a date.
