The sequence of noise levels used during sampling.
Can change the result, especially with few steps
The sampler defines the calculation method, while the schedule sets the noise levels used across the steps. Changing either can affect the result.Karras and normal are common options. Other schedules may suit particular model families or step counts. Start with the selected model's suggestions.The studio uses the Horde's published sampler constraints to list compatible schedules. If that information is unavailable, it offers Karras and normal.The form starts with Karras enabled. The API uses its own default when no schedule is specified.
The examples on this page were made from one prompt, one model and one seed, changing only the setting shown. Other pictures, models and settings respond differently; compare on your own request with the seed and the other settings fixed.
