Correction, 2026-10-01: this page said a Runway credit is $0.01 without saying that is the API price (Runway's app plans work out at more per credit), said most platforms reset credits without a source, and gave "two to four attempts per usable output" as a norm we have not measured. It also lacked a FAQ and sources. Fixed below.
A credit is a platform's internal unit for metering generation: you buy or receive a quantity, and each generation deducts an amount that depends on the model, the duration, and the settings.
The single most important property is that a credit is not a standard unit. It is defined by each platform, so "500 credits a month" means nothing until you know what a credit is worth and what a generation costs in them. Comparing two tools by credit count is the most common pricing mistake in this category.
What determines a credit's value
The platform's conversion rate. On 8frame a credit is $0.01 in a top-up pack. Runway sells API credits at $0.01 each, but on its app plans the rate differs: Standard is $15 a month for 625 credits, about 2.4 cents a credit. Same word, different value, sometimes inside one company.
What a generation costs in credits. A video clip might be 24 credits or 448 depending on the model, so a large allowance on an expensive model buys less than a small allowance on a cheap one.
Whether they expire. Credits that reset monthly are worth less than credits that carry over, because a quiet month is lost value. Runway's Standard and Pro monthly credits reset each billing cycle (only Max rolls over up to one month); on 8frame, subscription credits roll over while you stay subscribed.
How to compare two platforms
1. Convert credits to currency. Divide the pack price by the credits it contains.
2. Find the per-generation cost in credits for the model you will actually use.
3. Multiply by realistic attempts. Count how many tries a usable output takes on your own briefs, and multiply by that. It is the step everyone skips.
4. Check expiry.
That produces cost per usable clip, which is comparable. Credit counts are not. See how many credits does an AI video cost for a worked table.
Why platforms use credits instead of flat fees
Because generation costs the platform money per call, at rates that differ by model and change when providers reprice. A flat unlimited fee has to be funded by throttling heavy users or by light users subsidising them, and both are invisible at the point of purchase. Credits push that cost into the open, which is less comfortable and more honest. See is unlimited AI video actually unlimited.
Questions worth asking before buying
Do credits roll over? Can I top up mid-month without upgrading? Is the per-model price published or discovered at use? Does the same credit pool cover every model, or is it per-tool?
That last one matters more than it sounds: a pool covering every model lets you route each shot to the right one, and separate pools push you toward whichever tool you already have credits in.
