Stable Diffusion Sampling Methods

As of March 8, 2023, there are 19 samplers available in AUTOMATIC1111. They are:

• Euler a:
  • Strengths: Fast and easy to use.
  • Weaknesses: Not as accurate as some of the newer samplers.
• Euler:
  • Strengths: More accurate than Euler a.
  • Weaknesses: Slower than Euler a.
• LMS:
  • Strengths: Designed to produce sharp and detailed images.
  • Weaknesses: Slower than Euler and Euler a.
• Heun:
  • Strengths: More stable than Euler.
  • Weaknesses: Slower than Euler.
• DPM2:
  • Strengths: Faster and more accurate than Euler and Euler a.
  • Weaknesses: Not as stable as Heun.
• DPM2 a:
  • Strengths: More accurate than DPM2.
  • Weaknesses: Slower than DPM2.
• DPM++ 2S a:
  • Strengths: Faster and more accurate than DPM2 and DPM2 a.
  • Weaknesses: Not as stable as Heun.
• DPM++ 2M:
  • Strengths: More accurate than DPM++ 2S a.
  • Weaknesses: Slower than DPM++ 2S a.
• DPM fast:
  • Strengths: Faster than DPM.
  • Weaknesses: Less accurate than DPM.
• DPM adaptive:
  • Strengths: Designed to adapt to the complexity of the image being generated.
  • Weaknesses: Slower than DPM fast.

• DPM2 a Karras:
  • Strengths: More accurate than DPM2 Karras.
  • Weaknesses: Slower than DPM2 Karras.
• DPM++ 2S a Karras:
  • Strengths: Faster and more accurate than DPM++ 2S a.
  • Weaknesses: Not as stable as Heun.
• DPM++ 2M Karras:
  • Strengths: More accurate than DPM++ 2S a Karras.
  • Weaknesses: Slower than DPM++ 2S a Karras.
• DDIM:
  • Strengths: Designed to produce images with high-quality textures.
  • Weaknesses: Slower than the other samplers.
• PLMS:
  • Strengths: Designed to produce images with a painterly style.
  • Weaknesses: Slower than the other samplers.
