Fields

prompt: String

negative_prompt: Option<String>

Negative prompt — what the model should steer AWAY from. Optional: when None, sd-cli is invoked without --negative-prompt. Wire-format key: negativePrompt.

init_image_url: Option<String>

HTTPS URL to a base image for image-to-image generation. When set, the worker downloads the bytes to a local tempfile and invokes sd-cli --init-img <path>. Required for any task profile that declares the initImage capability.

mask_url: Option<String>

HTTPS URL to a black/white inpaint mask (white = the region the model may repaint). When set alongside init_image_url, the worker downloads it and invokes sd-cli --mask <path> so only the masked region changes. Wire-format key: maskUrl.

ref_image_url: Option<String>

HTTPS URL to a reference image for instruction-edit models (e.g. Qwen-Image-Edit / Flux Kontext). When set, the worker downloads it and invokes sd-cli -r <path> (reference mode) instead of the --init-img/--strength/--mask img2img path: the model regenerates the whole image from the reference per the instruction prompt; per-region clipping happens in the studio composite. Wire-format key: refImageUrl.

denoise: Option<f32>

Denoise / noise-strength for i2i (0.0 = keep init image unchanged, 1.0 = full re-noise). Maps to sd-cli --strength.

cfg_scale: Option<f32>

Classifier-free guidance scale. Per-job override; falls back to ModelSource.cliDefaults.cfgScale when None.

sampling_method: Option<String>

Sampler choice (euler, euler_a, dpm++2m, …). Per-job override; falls back to ModelSource.cliDefaults.samplingMethod.

width: u32

height: u32

steps: u32

seed: Option<u64>

ext: String
