Configuration for a prompt expansion request.

Fields

model_family: String

Diffusion model family (e.g. “flux”, “sd15”, “sdxl”).

task: ExpandTask

Resolved generation task and conditioning policy.

operation: PromptTransformOperation

Internal transform mode. Ordinary expansion remains the default.

remix_dimensions: Vec<RemixDimension>

Resolved, task-safe dimensions used only for Remix.

variations: usize

Number of prompt variations to generate (1 = single expansion).

temperature: f64

Sampling temperature (0.0-2.0). Higher = more creative.

top_p: f64

Nucleus sampling threshold.

max_tokens: u32

Maximum tokens for the LLM response.

thinking: bool

Enable Qwen3 thinking mode for higher quality (slower).

system_prompt: Option<String>

Custom single-expansion system prompt template (overrides built-in). Placeholders: {WORD_LIMIT}, {MODEL_NOTES}

batch_prompt: Option<String>

Custom batch-variation system prompt template (overrides built-in). Placeholders: {N}, {WORD_LIMIT}, {MODEL_NOTES}

family_overrides: HashMap<String, FamilyOverride>

Per-family overrides for word limits and style notes.

style: Option<String>

Optional visual style to weave into the expansion (per-request, set by the route handler from ExpandRequest::style — never from settings).

impl Default for ExpandConfig

fn default() -> Self

Returns the “default value” for a type.
