Plain-English explanation
Instead of charging a flat monthly fee for unlimited use, many hosted AI companion and image/video generation platforms sell or allocate credits: an internal balance you spend down as you use the service. A quick chat message might cost nothing or a fraction of a credit; a high-resolution image might cost a few credits; a video generation, which is far more computationally expensive, might cost tens of credits. When your balance hits zero, you either wait for a refill, upgrade your plan, or buy more.
The exact exchange rate between real money and credits, and between credits and specific actions, is set entirely by each platform and varies a lot from one service to the next.
Adult-AI use
Hosted AI platforms use credits to meter access and generation: a message counter that resets daily, a "this image costs 5 credits" prompt before you click generate, or a monthly allotment bundled into a subscription tier with the option to buy more. Because video and high-resolution image generation are much more expensive to run than text chat, credit pricing is also how platforms signal relative compute cost to users: a video generation reliably costs far more credits than a single chat reply or a standard-resolution image.
Credit systems also let a platform offer a free tier (a small daily or monthly allotment) alongside paid tiers, without having to meter and bill every single action separately.
Common uses
- A subscription tier that includes a fixed monthly credit allotment, with overage purchasable separately.
- Pay-as-you-go credit packs bought in bundles (e.g., 100, 500, 1000 credits) at a volume discount.
- Differentiated pricing within one platform: a fast/low-quality generation costing fewer credits than a slow/high-quality one.
- Free daily credit grants used as an onboarding or retention mechanic.
Limitations and misconceptions
- Credits are not a universal or interoperable currency: a credit on one platform has no relationship to a credit on another, and none of them typically convert to real-world cash if unused.
- Advertised credit costs can change as a platform adjusts pricing or as new, more expensive model options are added, so a generation that cost X credits last month may not cost the same today.
- Unused credits often expire at the end of a billing cycle depending on the platform's terms, which is easy to miss when comparing subscription tiers.
