ComfyUI Arena Suite v6.0.0

🚀 Modern ComfyUI Custom Node Suite - Automatic model caching and workflow optimization for ComfyUI.

✨ Features

• 🅰️ Arena AutoCache v6.0.0 - Fixed critical caching bugs, universal model parser, three Arena button modes (Gray/Red/Green)
• 🔧 Settings UI - Complete ComfyUI Settings integration with "💾 Save to .env" button
• 🎯 Universal Model Detection - Automatic detection of all model types without hardcoded node support
• ⚡ Parallel Caching - Multi-threaded model caching with background workers
• 🛡️ Safe Defaults - Always disabled by default, user must explicitly enable

🚀 Quick Start

Installation

1. Clone the repository:

   git clone https://github.com/3dgopnik/comfyui-arena-suite.git
   cd comfyui-arena-suite
   

2. Install dependencies:

   pip install -r requirements.txt
   

3. Copy to ComfyUI custom_nodes:

   cp -r . /path/to/ComfyUI/custom_nodes/ComfyUI-Arena/
   

4. Restart ComfyUI and navigate to Settings → Arena

🎯 Arena AutoCache

Three Modes

🔘 Gray Mode (Default) - System disabled

• ARENA_AUTO_CACHE_ENABLED=0, ARENA_AUTOCACHE_AUTOPATCH=0
• Uses original model paths

🔴 Red Mode - Active caching

• ARENA_AUTO_CACHE_ENABLED=1, ARENA_AUTOCACHE_AUTOPATCH=1
• Caches new models + uses cache
• Parallel prefetching of all workflow models

🟢 Green Mode - Cache usage only

• ARENA_AUTO_CACHE_ENABLED=1, ARENA_AUTOCACHE_AUTOPATCH=0
• Uses cache, doesn't cache new models
• Shows uncached model count in tooltip

Setup

1. Open ComfyUI Settings → Arena section
2. Fill Cache Root path (e.g., f:\ComfyUIModelCache\)
3. Click "💾 Save to .env" (creates user/arena_autocache.env)
4. Use Arena button in header to switch modes

Supported Model Categories

• checkpoints, loras, clip, vae, controlnet
• upscale_models, embeddings, hypernetworks
• gguf_models, unet_models, diffusion_models
• SUPIR, Flux, Wan, and all custom model types

🛠️ Technical Details

Architecture

• Settings Panel - Primary interface for configuration
• Arena Button - Intuitive mode switching
• Optional Node - Advanced users can override settings
• Deferred Autopatch - Always active, patching folder_paths.get_full_path()

Universal Model Parser

Instead of hardcoded node support, the system:

1. Scans widgets_values for model file extensions
2. Detects category using categoryByNodeType mapping
3. Falls back to filename-based category detection
4. Works with any node type automatically

Environment Variables

ARENA_AUTO_CACHE_ENABLED=1          # Enable/disable caching
ARENA_AUTOCACHE_AUTOPATCH=1         # Enable/disable autopatch
ARENA_CACHE_ROOT=f:\ComfyUIModelCache\  # Cache directory
ARENA_CACHE_MIN_SIZE_MB=10          # Minimum file size
ARENA_CACHE_MAX_GB=0                # Max cache size (0=unlimited)
ARENA_CACHE_MODE=ondemand           # Caching mode
ARENA_CACHE_VERBOSE=1               # Detailed logging

Testing

# Test caching with different workflows
python -m pytest tests/

Debugging

Enable verbose logging:

ARENA_CACHE_VERBOSE=1

Check logs in ComfyUI console for detailed caching information.

📝 Changelog
