Schedulers

Scale Scheduler Modes

What Is A Scheduler

• A scheduler changes your CFG Scale (or mimic scale) over time per step.
• For example, with Linear Up, if you have CFG Scale: 20 and CFG Scale Minimum: 5 for 20 steps, step 1 will be ran with CFG Scale: 5, step 10 with CFG Scale: 12.5 and Step 20 will be ran with CFG Scale: 20 (a smooth line increasing from 5 to 20).

The Schedulers

• Constant is effectively just disabled scheduling. Whatever your CFG Scale is, will be used throughout the render. This is how default SD runs normally.
• Half Cosine up is a pretty nice curve, Cosine Up and Linear Up work well too, a bit more situationally.
  • Note that Half as the name implies only maxes out at half the specified scale value (so set your CFG scale extra high for this scheduler). All others go the exact scale value for the final step.
• The Down schedulers are unlikely to be particularly useful in most cases.
• Power Up scheduler is very useful for refining small details, in combination with a very high CFG scale and a reasonable CFG minimum (it essentially runs at the minimum for most steps, then ramps up fast to the max for the last few steps, with the Power Scheduler Value controlling how fast it ramps up and for how many steps).

Extra Options

• The minimum values apply for all schedulers other than Constant
• Power Scheduler Value is exclusive to Power Up
