# overview

AnyInt supports more than one way to pay for usage.

At a high level, there are:

* `Pay As You Go` for prepaid balance-based usage
* `Plan subscriptions` for fixed recurring tiers
* `Custom subscriptions` for model-by-model recurring access

## How the billing models differ

| Billing model        | Best for                                        | How usage is charged                                           |
| -------------------- | ----------------------------------------------- | -------------------------------------------------------------- |
| Pay As You Go        | individuals, prototypes, variable workloads     | requests deduct from prepaid balance                           |
| Plan subscriptions   | users who want a predictable monthly tier       | one packaged tier with shared limits across included models    |
| Custom subscriptions | teams that want recurring access model by model | per-model configuration with separate service level and limits |

## Choose Pay As You Go when

* you do not want a recurring subscription
* your traffic is uneven or exploratory
* you want to top up balance and let API usage deduct from it directly
* you are testing models before committing to a plan

## Choose a plan subscription when

* you want a simple monthly tier
* you prefer one shared quota across included models
* you want predictable recurring access

## Choose a custom subscription when

* you want to buy recurring access model by model
* you need different limits per model
* you want to tune service level by model selection

## What pricing changes operationally

* which models are visible to your account
* which keys are valid
* whether requests consume prepaid balance or subscription entitlement
* what rate and usage limits apply
* how billing and invoice records are generated
