K2 Regional Sampler

Standard ComfyUI sampling plus per-step feedback to the K2 region plan. That feedback drives two things: late-step relaxation (spatial binding is gradually released after 55% progress so region edges do not look pasted on) and LoRA-delta adaptation. Without a connected plan this behaves like a normal KSampler. Krea 2 Turbo defaults: 8 steps, CFG 1.0, euler / simple.

NameTypeDefaultDescription
modelMODELPatched model from K2 Compose.
positiveCONDITIONINGCompiled positive conditioning.
negativeCONDITIONINGGlobal negative conditioning.
latentLATENTStarting latent — K2 Compose supplies an empty one, but any compatible latent works.
seedINT00–18446744073709550000Noise seed. Same seed + settings reproduces the run.
stepsINT81–1000Krea 2 Turbo is distilled for ~8 steps.
cfgFLOAT1.00–100Turbo is CFG-free; raising this is usually not an improvement. The RAW model uses CFG > 1.
sampler_nameCOMBOeulereuler is the Krea 2 Turbo default.
schedulerCOMBOsimplesimple is the Krea 2 Turbo default.
denoiseFLOAT1.000–11.0 for text-to-image; lower values keep more of a supplied latent (img2img / regional edit).
planoptK2_PLANK2 Compose plan. Enables late-step relaxation, LoRA-delta adaptation and the report.
