Nodepack under development. Manual written by AI, please open issue if something wrong or missing. If you upgrade, check attached new workflows or use git to downgrade to previous version if something failed.

ComfyUI core functions requirement: This nodepack uses new ComfyUI core functions. Update your ComfyUI installation before using. Use git pull on your ComfyUI folder.

All example workflows in the Workflow folder of the node root.

• Within Workflow folder you will find subfolders:
  • NewFE: workflows compatible with current ComfyUI front-end
  • Development: workflows for node testing only

About This Nodepack

Primere Nodes is not a collection of individual utility nodes. It's a consistent full-system solution architected around a central orchestrator (Primiere Model Control) that automatically adapts all generation parameters (sampling, CFG, VAE, CLIP, encoders, LoRAs, refiners) based on selected model type or individual checkpoint.

Why the complexity? Supporting 25+ diverse model architectures (SD1, SDXL, Flux, Hunyuan, etc.) with conflicting requirements demands a system-level approach. Each model expects different schedulers, sigma ranges, CFG scales, CLIP handling, and attention mechanics. Manual parameter tweaking per model is unsustainable at scale. Primere solves this by:

1. Saving per-model settings to JSON configs
2. Auto-loading correct settings when checkpoint selected
3. Enforcing compatibility between model type and network types (removing incompatible LoRAs, etc.)
4. Providing override capability for testing/optimization, then re-saving for future use

The workflow appears complex because it handles real-world generation scenarios (model switching, quality filtering, preview building, multi-stage refinement) that naive single-sampler approaches ignore.

Core generation pipeline. Single prompt input with full model concept support.

Central Orchestrator: Primiere Model Control node reads selected checkpoint, auto-loads saved settings (sampler, CFG, steps, VAE, CLIP, encoders, LoRAs, refiners), and distributes control_data tuple to all downstream nodes for automatic parameter application.

Supported model concepts: SD1, SD2, SDXL, Illustrious, SD3, StableCascade, Chroma, Z-Image, Turbo, Flux, Nunchaku, QwenGen, QwenEdit, WanImg, KwaiKolors, Hunyuan, Playground, Pony, LCM, Lightning, Hyper, PixartSigma, SANA1024, SANA512, AuraFlow.

Future support: HiDream, Mochi, WanT2V, WanI2V, Cosmos, Flux2, SSD, SegmindVega, KOALA, StableZero, SV3D, SD09, StableAudio, LTXV.
