How it works

To bootstrap a large test set or sweep many prompts, schnell gives the best images / credit ratio in the lineup.

Combined with the deterministic stage, one schnell base becomes dozens of stress variants at no extra cost.

Key points

  • 4 steps, very fast.
  • 1 credit / image — the cheapest.
  • Ideal for volume and dataset bootstrap.
