# Credits

> An internal balance that pays for generations, tracked in an immutable ledger.

TIGO uses an internal **credit** balance. Each generation estimates a cost up
front, reserves it, runs, then reconciles against the work actually performed.

## Pricing

Indicative base cost per generation type. Subject to change.

| Type             | Base |
| ---------------- | ---- |
| Text to 3D       | 12   |
| Image to 3D      | 16   |
| Multi-view to 3D | 20   |
| Retexture        | 10   |
| Remesh           | 4    |
| Rig              | 8    |
| Animate          | 6    |

**Modifiers**

| Modifier                 | Effect  |
| ------------------------ | ------- |
| Ultra quality            | `+8`    |
| No texture               | `×0.55` |
| PBR maps                 | `+4`    |
| 4K texture               | `+4`    |
| 8K texture               | `+10`   |
| Each extra export format | `+1`    |

The workspace shows the exact cost on the generate button before you commit.

## The ledger

Credits move only inside database transactions, and every change appends a row
to an immutable ledger.

| Entry type   | Meaning                                           |
| ------------ | ------------------------------------------------- |
| `PURCHASE`   | Credits bought or granted.                        |
| `GENERATION` | A debit for a job.                                |
| `REFUND`     | A credit back, for a failure or a reconciliation. |
| `BONUS`      | Signup or promotional grant.                      |
| `ADMIN`      | Manual adjustment.                                |

Your visible balance is a cached mirror of the ledger, written in the same
transaction as the ledger row.

## Refunds

* If a job **fails**, the full reserved amount is refunded.
* If a job **succeeds** for less than the reserved amount, the difference is
  refunded with a `credit-reconciliation` reference.
* If the engine rejects the request outright, nothing is charged.
