Qwen Image 2.1 Turbo 8-step vs original 25-step image quality showdown: 11 test sets in one graph. Proves the turbo LoRA 8-step schedule holds almost par with the original 25-step pipeline while generating far faster. 
 
Main features: 
- 11 test branches; each runs the Turbo 8-step pipeline (Turbo LoRA rank 178 + fixed 8-step ManualSigmas schedule, CFG 1, euler) against the original 25-step pipeline (KSamplerAdvanced 25 steps, CFG 3.5, euler) on the same prompt and seed 
- rgthree Image Comparer pairs every 8-step result with its 25-step counterpart for direct side-by-side judging 
- 11 pre-configured prompt / subject variations covering portraits, scenes and creative subjects 
- Final SaveImage (ComfyUI prefix) for the selected outputs 
 
Suggested workflow: 
1. Keep the 11 built-in test prompts for the comparison, or swap in your own 
2. Run the graph; both pipelines render per branch 
3. Judge in the comparer grid: 8-step results track the 25-step originals at a fraction of the time
