🚀 Latest Update: Unified Node & Enhanced Features

  • Unified Qwen3-VL Run Node: Replaced separate nodes with a single, powerful node handling all tasks (Captioning, Chat, Analysis).
  • JoyCaption Integration: Added built-in presets for various styles: Descriptive, Danbooru/e621 tags, Art Critic, Social Media, NSFW, and more.
  • Next Scene Generation: dedicated mode to generate cinematic "Next Scene" prompts optimized for video generation (WAN, Luma, etc.).
  • New Model Support: Added support for Abliterated (Uncensored) and Thinking Qwen3-VL models.

⚠️ IMPORTANT WARNING: It is highly recommended to use a dedicated folder for this workflow. The node will process every single image found in the specified path. Do not use a general directory (like your generic Downloads or Pictures folder) unless you intend to process all files within it.

☕ Support the Project

Building optimized tools requires deep dives and long hours. I build this because I believe in pushing the boundaries of what's possible locally. If you share that vision, your support helps bridge the gap between a rough experiment and a polished tool for everyone.
