<h2 id="what-is-qwen-image-lightning">What Is Qwen-Image-Lightning?</h2>Qwen-Image-Lightning is a distilled version of the Qwen-Image model, fine-tuned to maintain image quality while drastically reducing the number of inference steps required.The repo (<a target="_blank" rel="ugc" href="https://github.com/ModelTC/Qwen-Image-Lightning">https://github.com/ModelTC/Qwen-Image-Lightning</a>) currently offers:<ul><li>Qwen-Image-Lightning-8steps-V1.1 (bf16)</li><li>Qwen-Image-Lightning-4steps-V1.0</li></ul>Both variants are built to save time and compute without compromising too much on fidelity — ideal for both quick drafts and production work.Why distillation matters: The base Qwen-Image model is already powerful, but it can take 20–30 steps for optimal results. Distillation compresses the generation process, giving you near-identical quality at over 50% faster speed.Qwen-Image-Lightning’s GitHub repo includes ready-made ComfyUI workflow JSON files:<ul><li><code>workflows/qwen-image-8steps.json</code></li><li><code>workflows/qwen-image-4steps.json</code></li></ul>These are pre-configured to get you up and running with minimal setup.<h2 id="how-to-use-qwen-image-lightning-in-comfyui">How to Use Qwen-Image-Lightning in ComfyUI</h2><h3 id="1-install-or-update-comfyui">1️⃣ Install or Update ComfyUI</h3>Make sure you’re running a recent (preferably nightly) build for best compatibility.
