# How credits work

> Estimates before you generate, deductions when you submit, and the final charge.

**Credits** are WJI's unit of spend. Every generation costs credits, and the amount depends on the
model and what you asked it to produce.

## Where credits come from

| Source                         | Amount                                                                      |
| ------------------------------ | --------------------------------------------------------------------------- |
| **Monthly free grant**         | 300 credits a month, on the anniversary of your sign-up rather than the 1st |
| **Subscription**               | 4,500 a month on VIP, 10,000 on SVIP                                        |
| **Top-up packages**            | 3,000, 9,000, or 30,000 credits                                             |
| **Gift cards and promo codes** | Whatever the code carries                                                   |

Credits arrive in separate buckets, and the buckets have different expiry dates.

## The order credits are spent in

<Warning>
  Credits are **not** spent oldest-first. WJI spends **the bucket that expires soonest**, and among
  buckets that never expire it spends granted credits before purchased ones.
</Warning>

This works in your favour — expiring credits get used before they are lost — but it does mean your
purchased balance can sit untouched while granted credits drain.

## The three stages of a charge

</Frame>

<Steps>
  <Step title="Estimate, before you commit">
    The generate button carries an estimated cost, recalculated as you change the model, prompt,
    ratio, batch size, duration, or references.
  </Step>

  <Step title="Deduction, on submit">
    Your balance drops immediately so you can see where you stand. For models billed by actual
    duration, nothing is deducted up front — the charge waits for the result.
  </Step>

  <Step title="Settlement, on completion">
    Once the result exists, WJI knows the real duration and settles the true cost. The history entry
    then shows the actual credits charged.
  </Step>
</Steps>

## Three billing modes

| Mode           | Used for                                          | The estimate shows                |
| -------------- | ------------------------------------------------- | --------------------------------- |
| **Fixed**      | Images, and video where you chose the duration    | A total                           |
| **Per second** | Models where the duration is decided by the model | A rate, plus an upper bound       |
| **Per minute** | Certain video enhancement models                  | A rate, always settled afterwards |

## Refunds on failure

A failed generation is refunded. In a batch, the refund is **proportional** — five clips requested,
two failed, two clips' worth comes back. Refunds appear against the original charge in your records.

<Warning>
  This applies to the generation pipeline. In **Digital Host**, failed generations are still charged
  and counted in the program's credit total.
</Warning>

## Where to see your balance

| Place                   | Shows                                                        |
| ----------------------- | ------------------------------------------------------------ |
| Top navigation badge    | Your balance, with floating +/- animations as it changes     |
| Workspace app bar badge | The workspace's remaining allowance and limit                |
| Dashboard balance card  | Total credits, and each bucket's remaining amount and expiry |
| Usage page              | Statistics, consumption, and top-ups                         |

Inside an organization, the badge shows your spendable allowance there rather than your personal
wallet.

## Workspace limits

A workspace can carry a **total** and a **monthly** spending cap. Hitting one stops generation with a
message saying the workspace has reached its total or monthly limit.

<Note>
  For features where the cost cannot be estimated in advance, such as streaming chat, a workspace
  that has spent exactly its limit cannot start new work — it does not need to exceed it.
