Default: 28

Optional<string>output_format

The format of the generated image.

Allowed values: jpeg, png

Optional<boolean>preprocess_depth

If set to true, the input image will be preprocessed to extract depth information. This is useful for generating depth maps from images.

Default: true

Optional<string>control_lora_image_url

The image to use for control lora. This is used to control the style of the generated image.

Optional<array<object>>loras

stringstatusrequired

Current public run status.

Allowed values: pending, running, completed, failed, timeout

Optional<string>model

Public SandBase model name used for this run.

Optional<array<object>>outputs

Present only for completed runs. Each object is capability-specific; inspect the selected model schema for its fields.

Optional<object>error

Present only for failed or timeout runs. Contains a public error type and sanitized message.
