# Ideogram 4.5

> Ideogram · `ideogram-4.5` · image

## Identifier

Use the model identifier `ideogram-4.5` in the `model` field when calling [`/asset/start`](/api-reference/assets/start).

## Capabilities

| Property | Value |
| - | - |
| Reference inputs | 0–5 |
| Aspect ratios | `16:9`, `9:16`, `1:1`, `3:2`, `2:3`, `4:3`, `3:4` (default `9:16`) |
| Resolutions | `1K`, `2K` (default `2K`) |
| Max prompt length | 10000 chars |
| Tags | `new` |

## Inputs

Pass reference media in the `references` array (0–5 items). Optional. Each item accepts exactly one of:

* `url` — a direct, publicly accessible file URL
* `asset_id` — the ID of an existing asset in your Hoox space (e.g. a previous generation)
* `avatar_id` — the ID of an avatar defined in your Hoox space

## Custom settings

These keys go inside the `model_settings` object of the request body.

| Key | Type | Default | Affects cost | Description |
| - | - | - | - | - |
| `quality` | select | `medium` | yes | Rendering effort. Higher quality means more detail and a higher price. Options: `low`, `medium`, `high`. |
| `editPrecision` | select | `regular` | no | Only used when editing an image. high is a precise edit that restores every pixel the prompt does not touch, and keeps the source image's size: aspect ratio and resolution are then ignored. Options: `regular`, `high`. |

## Pricing

Default parameters (`2K`): **\~0.6 credits / generation**.

For exact pricing with your own parameters, call [`/asset/pricing`](/api-reference/assets/pricing) with the `model` and any parameters that affect cost.

## Example request

```json theme={null}

}
```

See [`/asset/start`](/api-reference/assets/start) for the full request/response reference, error codes, and code samples in cURL / Python / JavaScript.
