Seed and Parameter Control

10 min
advanced

Seeds are random numbers that initialize the generation process. Same seed + same prompt = same (or very similar) output. Learning to use seeds strategically is a powerful consistency tool.

Key Concepts

  • 1
    Seeds initialize the random generation process
  • 2
    Same seed + same prompt ≈ same result
  • 3
    Find good seeds and save them
  • 4
    Vary prompts while keeping seed constant
  • 5
    Different platforms handle seeds differently

Examples

Prompt
Portrait of Maya Chen [character bible] --seed 12345 (vary lighting, pose, background while keeping seed)
Result

More consistent face across variations

Pro Tips

In Midjourney: use --seed [number]
In Stable Diffusion: set seed in generation settings
When you get a good face, note the seed immediately
Seed + slight prompt changes = controlled variation

Summary

Seeds are your consistency multiplier. Find good ones and use them strategically.
