Inputs (37)

Name	Type	Default	Description
mode	COMBO	grid	2 options: grid, combos
stage_scope	COMBO	s1	Which stage(s) the swept keys apply to. all_stages sets the same value on s1+s2+s3 together (NOT a per-stage cross product). Workflow intent: perfect S1 first (quick_screen), then sweep s2/s3 refinement on the short list.
samplersopt	STRING	euler, res_2m, res_2s, deis_3m, abnorsett_3m, abnorsett_4m, lawson4_4s, etdrk4_4s, er_sde, rk6_7s, lcm, lcm_hybrid, lcm_hybrid2	Comma/newline-separated. Allowed: euler, res_2m, res_2s, deis_3m, abnorsett_3m, abnorsett_4m, lawson4_4s, etdrk4_4s, er_sde, rk6_7s, lcm, lcm_hybrid, lcm_hybrid2. Pre-populated with all of them - delete what you don't want. Blank = not swept. Crossed with hybrid_steps, only the hybrid samplers expand per split value; other samplers keep one cell (inert-split dedupe).
schedulersopt	STRING	linear, balanced, karras, beta57, beta, bong_tangent, exponential, linear_quadratic, simple, 4mp-lcm, Candidate 1, Claude-1, Claude-8mp, EXP1, EXP2, EXP3, EXP4, EXP5, EXP6, Kreamania3-2stage-4.5mp, OPT-AB412, OPT-DEIS12, kreamania3-2stage-8mp	Built-in schedules AND saved sigma-shape ★ preset names, mixed freely: each entry is tried as a schedule (linear, balanced, karras, beta57, beta, bong_tangent, exponential, linear_quadratic, simple) first, then as a sigmas preset (applied as a full profile for that cell); unknown names are SKIPPED with a console warning instead of aborting. Pre-populated with everything available - delete what you don't want. Blank = not swept.
pair_lockopt	BOOLEAN	false	ON: zip samplers+schedulers line-by-line into fixed pairs (lists must be equal length) - for testing known recipes. OFF: full cross product.
stepsopt	STRING		e.g. '8, 10, 12'. Maps to <stage>_steps.
windowsopt	STRING		Refine windows 'start-end', e.g. '5-12, 6-12, 7-12'. Maps to <stage>_start_step/<stage>_end_step. Pair with matching steps or leave steps blank and window within the panel's step count.
etasopt	STRING		e.g. '0, 0.3, 1.0' -> <stage>_eta.
noise_typesopt	STRING		Allowed: white, low_freq, high_freq, pink. lcm-family samplers force white (per the 2026-07-23 rainbow fix); those cells are auto-coerced and labeled, never silently divergent.
cfgsopt	STRING		e.g. '1.0, 1.5, 2.0' -> <stage>_cfg. Diagnostic for RAW-drifted fine tunes: tolerance of cfg>1 tracks how far training eroded the turbo distillation.
shift_modesopt	STRING		distilled_shift values to sweep: fixed / resolution / manual.
musopt	STRING		shift mu values for the scoped stage(s), e.g. '1.15, 2.1, 3.0'. Forces distilled_shift=manual on those cells (unless shift_modes is also swept, which then wins the cross).
combos_fileopt	STRING		combos mode: path to a JSON file with the runs - either a JSON array of override objects, {"combos": [...]}, or JSON-lines. Takes precedence over combos_json below. Keeps sweep campaigns as versionable files.
combos_jsonopt	STRING		combos mode: one JSON object per line using Ultra V2 widget keys (same keys as presets / PNG recipes), e.g. {"s2_sampler": "lcm_hybrid", "s2_steps": 12, "s2_start_step": 6} Copy-paste directly from a preset or a stamped PNG.
seed_policyopt	COMBO	fixed	fixed: every cell uses the Ultra panel seed (required for fair comparison). seeds_axis: 'seeds' below becomes one more grid axis.
seedsopt	STRING		seeds_axis values, e.g. '1, 2, 3'.
quick_screenopt	BOOLEAN	false	Force S1-only at screen_megapixels for every cell (upscale_to_stage2/3 = 0). Cheap wide screening; re-run the short list full-pipeline after.
screen_megapixelsopt	FLOAT	1.000.25–8	—
score_metricsopt	BOOLEAN	true	Compute technical metrics per cell (CPU, ms): Laplacian + Tenengrad sharpness, wavelet noise sigma, flat-region chroma variance (splotch detector), clip fraction. Scores annotate + can sort the sheet; they never hide a cell.
sort_byopt	COMBO	plan_order	Contact-sheet order. Metrics sort best-first; time_s fastest-first. Manifest keeps plan order + this ordering separately.
tile_pxopt	INT	448128–1024	—
max_combosopt	INT	641–4096	Hard cap. Over-cap plans REFUSE with an axis-size breakdown (no silent truncation).
output_folderopt	STRING		Where sweep folders are created. Blank = ComfyUI output/sweeps. An absolute path is used as-is; a relative path is created under the ComfyUI output directory.
hybrid_stepsopt	STRING		Sweep the hybrids' handoff in EXACT lcm steps, e.g. '3, 4, 5, 6' -> <stage>_hybrid_steps for the scoped stage(s). Only lcm_hybrid / lcm_hybrid2 read it - pair with a hybrid in the samplers axis (or on the panel); inert cells are deduped. Values clamp inside each stage's window so both halves always run; sweeping values past window-1 collapses to the same cell.
megapixelsopt	STRING		Sweep s1_megapixels, e.g. '0.5, 1.0, 2.0, 4.5'. Always targets Stage 1 regardless of stage_scope (stage 2/3 sizes chain from it via the upscale factors). Mixed cell sizes are fine: metrics and the contact sheet use each cell's native output; the IMAGE batch output center-pads smaller cells to the largest. quick_screen does NOT override a swept megapixels value. Note: resolution changes the noise grid, so composition shifts with size even at a fixed seed - that is part of what you are measuring.
lora_modeopt	COMBO	none	bakeoff: each LoRA in lora_files at each lora_strengths value - by default the swept LoRA runs ALONE (panel stack replaced) so every style is measured against the bare checkpoint; keep_panel_stack layers it on top instead. strength_ladder: keep the panel-declared stack, step ONLY the lora_target entry through lora_strengths. Sweep-injected entries are ephemeral (fused per cell, cleaned per cell).
lora_filesopt	STRING		bakeoff: one LoRA per line - a name from the loras folder (same resolution as the LoRA Stack node) or a full path.
lora_strengthsopt	STRING		e.g. '0.6, 0.8, 1.0'. One value drives all three stage weights (weight_s1=s2=s3). bakeoff: every file at every value; ladder: the target entry's values.
lora_targetopt	STRING	1	strength_ladder: which panel-stack entry to vary - 1-based index, or a name substring (matches lora_name/filename).
include_baselineopt	BOOLEAN	true	Add one reference cell: bakeoff = no LoRA at all (or the panel stack alone when keep_panel_stack is ON); ladder = the panel stack exactly as declared.
keep_panel_stackopt	BOOLEAN	false	bakeoff only: append the swept LoRA ON TOP of the panel stack instead of replacing it.
promptsopt	STRING		One prompt per line = a prompt axis (slowest axis, so the sheet and CSV read in prompt-major blocks). Each prompt cell re-encodes (prompt_conditioning is cleared; ~seconds/cell). Metric comparisons are only meaningful WITHIN a prompt block.
sigma_profilesopt	STRING		Comma/newline list of saved sigma-shape preset NAMES (the ★ presets of the Eric Krea2 Sigmas node). Each cell rebuilds the full bundle from that preset and it OVERRIDES any wired sigmas node for that cell. Blank = not swept.
lora_triggersopt	COMBO	append	bakeoff: merge each cell's swept-LoRA trigger words into that cell's prompt (from the LoRA Stack node's cached trigger database; first-seen files may do one network lookup, non-fatal on failure). Only sweep-injected entries contribute - baseline and ladder cells are untouched. A cell whose prompt text changes re-encodes automatically. Effective prompt + triggers are recorded in the cell's metadata.
enabledopt	BOOLEAN	true	Off = the node outputs nothing and Ultra V2 runs a normal single generation - leave the sweep wired in the workflow and toggle it.
sweep_presetopt	COMBO	custom	Named sweep plans from sweep_presets.json. Selecting one WRITES its values into this panel (so you can see exactly what will run); editing any field flips back to 'custom'. Save the panel as a preset with the ★ button. Headless/API: the named preset applies fully. Ask Claude to author experiment presets.
preset_notesopt	STRING		One or two sentences: what this sweep preset is FOR and what it does. Saved and loaded with the ★ preset - so future-you remembers why it exists.
