🔧 What is this?

comfyui-grok-prompts is a modular node suite for ComfyUI that uses xAI’s Grok LLM API to transform user input into optimized prompts for AI models like PonyXL and Flux. These nodes intelligently:

• ✂️ Split prompts into subject/scene (text_l) and style/mood (text_g)
• 🔀 Combine and rewrite them into perfectly scored Danbooru-tagged prompts
• 🎥 Output video prompts using Wan’s Advanced Prompt Formula
• 💬 Display a UI explanation of how the prompt was refined
