Diffusion Sampling Steps
Definition
Sampling steps count the updates during generation by a diffusion model.
The number of numerical or denoising updates with which a diffusion sampler generates an output from an initial state. It is only meaningfully comparable together with model, scheduler, and solver.
Simply explained
An output is generated in multiple computational steps; their number must be considered together with the procedure used.
Why it matters in practice
The term helps to select, develop, evaluate AI systems in a well-founded manner and realistically assess their technical risks.
Example from business
An image model generates an output in 30 denoising steps.
Limits and pitfalls
- Equating more steps generally with higher quality, mixing training steps and inference steps, or directly comparing values of different samplers.
Origin & history
The metric became widespread with diffusion models and their discrete or numerical samplers; it is not a general measure for all generative sampling methods.
Use in mid-sized companies
- Possible example: An image model generates an output in 30 denoising steps.
