Subscriptions, credits or ads?
Subscriptions fund recurring access, credits charge against a usage balance, and advertising can help fund eligible usage without charging the user directly. An AI app can combine these models according to usage costs, user preferences and suitable advertising opportunities.
Three ways to fund it.
Ads
Subscription
Credits
Illustrative examples.
Compare the models.
| Model | Best suited to | What it offers | The trade-off |
|---|---|---|---|
| Subscriptions | Regular users who value ongoing access. | Recurring revenue and a clear paid tier. | Upfront commitment can deter casual users. Heavy usage still needs cost controls. |
| Credits / pay-per-use | Occasional tasks or generations with different costs. | Charges aligned with usage and the value of each task. | Top-ups and per-use costs can make casual users hesitate. |
| Advertising | Users who prefer free access, where an ad fits the experience. | Revenue from eligible usage without charging the user directly. | Revenue depends on available demand and measured ad delivery. |
Purchased credits prepay a usage balance; promotional credits may be granted for free. Metered billing charges for measured usage. Freemium defines what is free, not how that usage is funded.
Here, Generative Engine Advertising (GEA) describes advertising in generative AI experiences. With wavebird, these placements stay separate from model instructions and generated output.

Add credits to either path.
Example product design. You set the allowances, ad policies and paid benefits; subscribing does not have to be the only way to buy more usage.
