AI on the Lot 2026 - QwenVL - Prompt Enhancer is a lightweight ComfyUI workflow that turns a short idea into a rich, production-ready prompt. It uses the AILab_QwenVL_PromptEnhancer node to pass your input through a Qwen-VL language model, which expands key details like subject attributes, mood, composition, and technical cues. The output is displayed with PreviewAny so you can quickly copy it into any downstream image or video generation pipeline.
Technically, the workflow is a simple but effective chain: your text input is formatted into an instruction for Qwen-VL, the model generates a polished prompt that preserves intent while adding concrete visual language, and PreviewAny renders the final string for inspection. Because the output is plain text, it works with common ComfyUI text fields (e.g., positive prompts for Stable Diffusion or other T2I nodes). This makes it especially useful for teams and beginners who want consistent, detailed prompts without hand-writing long templates.
