Qwen-Image-2512-lightx2v

This ComfyUI workflow is a Qwen-Image-2512 text-to-image pipeline accelerated by the Lightx2v “Lightning 4-steps” LoRA . It loads the core components— UNet ( qwen_image_2512_bf16.safetensors ), text encoder/CLIP ( qwen_2.5_vl_7b_fp8_scaled.safetensors , type qwen_image ), and the VAE ( qwen_image_vae.safetensors )—then applies a model-only LoRA via LoraLoaderModelOnly using the Lightx2v 4-step checkpoint ( Qwen-Image-Edit-2512-Lightning-4steps-V1.0-bf16.safetensors ) at strength 1.0. Generation is done with an EmptySD3LatentImage (e.g., 1472×1104) and a KSampler configured for ultra-fast 4-step sampling (steps=4, cfg=1, sampler= euler , scheduler= simple , denoise=1). Your positive prompt text is fed into the Positive CLIPTextEncode , while the Negative CLIPTextEncode holds a “quality control” negative prompt; the sampled latent is then VAE-decoded and saved . In practice, you mainly tweak: prompt text, resolution, seed/randomize, and (rarely) CFG—this workflow is intentionally tuned so Lightx2v stays stable at 4 steps for fast output. 🎥 YouTube Video Tutorial Want to know what this workflow actually does and how to start fast?
