Its main purpose is to help creators compare how different Z-Image acceleration LoRAs affect speed, image quality, prompt adherence, composition stability, and final visual detail under the same base model and prompt structure.The workflow uses z_image_bf16.safetensors as the main Z-Image Base model, qwen_3_4b.safetensors as the text encoder, and ae.safetensors as the VAE. The generation canvas is set to 1280 x 720, which is a practical landscape format for cinematic images, comparison previews, YouTube thumbnails, Bilibili covers, Civitai showcase examples, and RunningHub workflow demonstrations.The core design is a multi-route comparison structure. One route uses a more standard Z-Image Base generation setup with a higher step count, while the other routes apply different Z-Image Fun Distill LoRA versions for accelerated generation. The workflow includes 2602 and 2603 acceleration LoRA paths, including 8-step, 4-step, and 2-step versions. Each route uses its own model-loading and KSampler structure, so users can directly compare how the same prompt behaves when sampling time is reduced.This is useful because acceleration is not only about speed. A 2-step route may be extremely fast, but it may lose fine detail, texture richness, or composition stability. A 4-step route may provide a better balance between speed and quality. An 8-step route usually gives the model more room to build lighting, structure, and detail. By placing these routes in one workflow, creators can judge which version is best for preview generation, batch testing, online publishing, or final image output.The prompt used in the workflow describes a dramatic silhouetted warrior standing in a field of red spider lilies against a huge blazing orange sun. This is a strong test prompt because it contains high-contrast lighting, atmosphere, silhouette structure, foreground elements, color intensity, and cinematic composition. The same kind of prompt makes it easier to observe whether each LoRA route preserves the image’s core visual impact.The workflow also uses shared negative prompt logic to reduce common issues such as bad lighting, overexposure, underexposure, low contrast, sketch-like output, cartoon drift, blur, and ugly artifacts. This keeps the comparison more controlled and makes the difference between the LoRA routes easier to evaluate.In short, this is a practical Z-Image Base acceleration benchmark workflow. It helps users decide whether 2-step, 4-step, or 8-step 2603 LoRA generation is the best choice for their own production needs.
