Vantage DyPE Node for ComfyUI

Dynamic Position Extrapolation for Ultra-High-Resolution Flux Models

---

🧠 Overview

Vantage DyPE brings DyPE (Dynamic Position Extrapolation) directly into ComfyUI, allowing Flux-based diffusion transformer models to generate native ultra-high-resolution images — up to 8K — without retraining or using any external upscalers.

DyPE dynamically modulates the model’s positional embeddings during denoising, preserving geometry, proportion, and texture fidelity even when rendering far beyond the model’s original training resolution.

⚡ Generate true 4K+ images natively in ComfyUI using your existing Flux models — fully training-free, stable, and VRAM-optimized.

✨ Features

• 🧩 Seamless Flux Model Patching (Krea, Kontext, Dev, etc.)
• ⚙️ Native High-Resolution Sampling — supports 2K, 4K, 8K outputs
• 🌀 Integrated DyPE Positional Modulation (Yarn / NTK / Base)
• 🧮 Smart Sigma (σ) Remapping for large token grids
• 🧠 Adaptive Precision switching (fp16 / bf16)
• 💾 GGUF / Quantized Model Support for low-VRAM setups
• ⚡ Performance Mode — optimized memory & compute speed
• 🔲 Empty Latent Generator — create quick zero-latent tensors for testing

🧰Installation

1️⃣ Locate Your Custom Nodes Folder

Navigate to your ComfyUI installation directory and open:

ComfyUI/custom_nodes/

2️⃣ Clone or Copy the Node

Clone this repo directly inside custom_nodes:

git clone https://github.com/vantagewithai/Vantage-DyPE.git

Or manually copy the Vantage-DyPE folder into:

ComfyUI/custom_nodes/Vantage-DyPE/

3️⃣ Restart ComfyUI

After installation, restart ComfyUI.
The node will appear under Vantage → Model → / Patches.

⚙️ Usage Guide

1. Load a Flux-based model (Flux Krea, Flux Kontext, Flux Dev, etc.) using a:

   • Diffusion Model Loader (for safetensors)
   • UNet Loader (for GGUF)

2. Model Format Support:

   • ✅ .safetensors (BF16 or FP8 scaled)
   • ✅ .gguf (quantized)

3. If Using GGUF Models:

   • Enable the UNet Loader Node.
   • Connect UNet Loader → LoRA Loader → Sampler.
   • Disable the Diffusion Loader Node.

4. Load Additional Models:

   • 🔥 Flux Turbo Alpha LoRA — enables 8-step fast sampling.
   • 🎨 VAE Model: sd-vae-ft-mse (recommended).
   • 🧠 Encoders: CLIP-L and T5-XXL (text conditioning).

5. Connect Model Output → Vantage DyPE Node.
   Configure:

   • method: Extrapolation method (yarn recommended)
   • enable_dype: Enable/disable DyPE
   • dype_exponent: Modulation strength (2.0 default)
   • base_shift / max_shift: Sigma remapping curve
   • adaptive_precision / performance_mode: Precision & VRAM options

6. Connect DyPE Output → KSampler → VAE Decode.

💡 Tip: Keep both width and height divisible by 64 for stable geometry and best Flux attention alignment.

📏 Recommended Resolutions

Type	Resolution	Notes
Square	1024×1024 → 4096×4096	Best structural accuracy
Landscape	1920×1080 / 3840×2160	Cinematic / 4K UHD
Portrait	2160×3840	Stable up to 3K vertical
Ultra	4096×4096+	Requires ≥24GB VRAM

---

⚙️ Recommended Settings

Parameter	Recommended	Description
method	yarn	Stable & accurate extrapolation
dype_exponent	2.0	Balanced between sharpness & stability
base_shift	0.5	Smooth low-resolution adaptation
max_shift	1.15	Ideal for 4K generation
performance_mode	off	Keep off for GGUF or quantized models
adaptive_precision	on	Enables dynamic fp16/bf16 switching

---

🧩 Example Workflow

1. Load model (Flux Krea / Kontext / Dev).
2. Add Flux Turbo Alpha LoRA for fast 8-step sampling.
3. Insert Vantage DyPE Node between model loader and sampler.
4. Configure resolution and settings.
5. Connect to sampler and VAE decode node.
6. Run generation and enjoy native 4K output — no upscaler needed!

📸 Example Results

Resolution	Model	Steps	Description
3072×3072	Flux Krea + DyPE + Turbo LoRA	8	Realistic portrait with perfect tone balance
3840×2160	Flux Krea + DyPE	8	Native UHD fidelity without upscaling
4096×4096	Flux Kontext + DyPE	12	Stable ultra-detailed render

🧩 Troubleshooting

Issue	Possible Cause	Fix
Elongated / squashed images	Non-multiple of 64 resolution	Use width & height divisible by 64
GPU memory overflow	Too high resolution or FP32 mode	Enable performance mode or lower res
Weak detail at edges	Low dype_exponent	Increase to 2.0–2.5
Over-sharpening	High dype_exponent or aggressive sigma shift	Reduce to 1.5–2.0
No output with GGUF	Incorrect loader wiring	Use UNet Loader → LoRA Loader path
