- Effective $ per second
- We compute the full cost of one clip for your spec — including per-generation minimums, fixed clip lengths, token formulas and credit conversions — and divide by the clip's length. Raw advertised $/s is never compared directly.
- Same model only
- Each page compares vendors selling one exact model variant as named by its maker. Faster or cheaper variants (e.g. Fast, Mini, Lite) have their own pages. Vendor-made variants such as "Turbo" builds are not mixed in.
- Claimed vs verified
- We list a vendor's model under the name the vendor gives it. Until we have checked it with our own test generations, it is marked "claimed".
- Default view
- By default we show what you can call via API and pay as you go. Turn on "Include subscription apps" to compare subscription plans and web apps too — useful when you produce at volume.
- Subscriptions
- Plans are converted at plan price ÷ included credits and assume you use every credit (best case). The plan price is always shown next to the number. Unlimited or slow-queue modes are noted, never priced.
- Official price
- Each model's reference is the maker's own API price. "Below official" is a factual comparison; we don't claim a vendor is subsidising.
- Promos
- Temporary discounts with an end date are included at the price you'd pay today and marked with their end date.
- Freshness
- API prices are re-read daily; prices read from pages or checked by hand show when they were last verified. An offer not verified in 7 days (14 for hand-checked) is marked stale and can't be the cheapest; after 30 days it's hidden.
- Review
- Any price change read from a vendor page, and any move larger than 50 %, is reviewed by a person before it's published.
- Affiliate links
- Some "Go" links are affiliate links, marked "affiliate" next to the button. They never affect the ranking.
- Why free / how we earn
- The site and its price alerts are free. When you sign up with a vendor through an affiliate link, that vendor may pay us a commission — at no extra cost to you. That's how we fund the daily price collection. We don't sell your data or rank by commission.
- Currency
- Prices are shown in USD. EUR-priced plans are converted at a fixed rate stated in the offer's notes.
