 "title": "Trade speed for quality by swapping schedulers",
 "page_title": "How to trade speed for quality by swapping schedulers with Diffusers",
 "summary": "Combine pretrained models with different noise schedulers to control how many steps generation takes.",
 "who": "An ML practitioner who wants faster generation or to understand how diffusion sampling works.",
 "problem": "Default sampling settings are often slower than needed, and the pipeline hides how sampling works.",
 "outcome": "A custom denoising loop or pipeline with a scheduler and step count you chose.",
 "steps": [
  "Install with `pip install --upgrade diffusers[torch]`",
  "Load a scheduler and model separately, for example `DDPMScheduler.from_pretrained(\"google/ddpm-cat-256\")` and the UNet2DModel from the same repo",
  "Set the number of steps with scheduler.set_timesteps(50)",
  "Loop over scheduler.timesteps, predict the noisy residual with the model and step the scheduler",
  "Try other schedulers from the Loading guide and compare speed and output quality"
 ],
 "agent_prompt": "Using huggingface/diffusers, write a denoising loop with DDPMScheduler and UNet2DModel from google/ddpm-cat-256 as in the README, then try two other schedulers at fewer steps and save a side-by-side image comparing speed and quality.",
