The conditioning output should then connect to the sampler's positive prompt input. The default settings should work well with Z-Image turbo. -The randomize_percent setting determines what percentage of the embedding values will be randomly selected for modification with noise. The strength setting adjusts the scale of the noise. The seed value determines which values to modify and with what noise. By default, the noise_insert setting is set to "noise on beginning steps." By removing the noise before the end of the generation, the model will have time to pivot back towards prompt adherence. Steps_switchover_percent specifies what percentage of steps are process before switching embeddings. "Noise on all steps" will reduce prompt adherence and text rendering significantly more so. For adjusting to a different step schedule, use this formula to calculate which percentage setting to use: (100/TOTALSTEPS) * STEPS - 1. +The randomize_percent setting determines what percentage of the embedding values will be randomly selected for modification with noise.

For adjusting to a different step schedule, use this formula to calculate which percentage setting to use: (100/TOTALSTEPS) * STEPS - 1. Strength values in the range of 15 to 30 and a randomize_percent of 50 are reasonable starting points for use with Z-Image Turbo. The steps_switchover_percent defaults to 20%. Some prompts will benefit from higher or lower settings. Longer more detailed prompts provide more tokens for SeedVarianceEnhancer to manipulate. Somewhat counterintuitively, use with more detailed prompts may result in more diverse outputs. ## Advanced usage: -SeedVarianceEnhancer includes an embedding masking feature, which excludes portions of the embedding from exposure to noise. Masking can protect portions of the prompt. The mask_starts_at setting controls wether the masks extends from the beginning or end. Mask_percent controls how far the mask extends. Setting mask_starts_at to beginning and mask_percent to 50 will mask the first half of the prompt. If the prompt is structured so that critical details are in the first half and less important details are in the second, the image generations should more consistently adhere to the critical details. +SeedVarianceEnhancer includes an embedding masking feature, which excludes portions of the embedding from exposure to noise.

SeedVarianceEnhancer nodes can be chained together. The noise from each node will add up. The node only uses the first embedding of a conditioning, so chaining to a node set to "noise at end steps" will not work.
