Seeds, retries and refunds: iterate deliberately
TL;DR — Every render records a seed, and the same seed with the same prompt and settings reproduces the same image exactly. Iterate by locking the seed and changing one variable at a time — and remember failed or filtered generations refund automatically, so you only pay for delivered images.
Most wasted credits go to blind re-rolling: generating the same prompt again and again, hoping the dice land differently. Seeds turn generation from a slot machine into an engineering tool — reproducible, comparable, and cheap to iterate.
This guide covers how reproducibility works, how to iterate deliberately, exactly when credits come back automatically, and how to budget for experimentation.
Step by step
- 1Understand what a seed does
The seed is the starting point for a render's randomness. The same seed with the same prompt, model, and settings reproduces the same image exactly; change any one input and you get a controlled variation instead of a completely new roll.
- 2Lock the seed, change one variable
When a render is almost right, reuse its seed and adjust only the element that is wrong — swap the outfit, fix the setting, tweak one phrase. Because everything else is held constant, you can compare before and after and know exactly what your change did.
- 3Re-roll only when exploring
Fresh seeds are for discovering new compositions, not for fixing details — a detail problem survives a re-roll far more often than it gets fixed by one. Do exploration at 720p, where each attempt costs 12 credits, and save higher tiers for renders you intend to keep.
- 4Know the refund rules
Failed generations are refunded automatically and immediately — the credits reappear in your balance with no support ticket. The same applies to generations blocked by content filters, and to a failed model training run (720 credits back). If a charge for a failed run ever sticks, contact support via the Help Center.
- 5Budget an experiment allowance
Reserve roughly 10 to 15 percent of your monthly credits for exploration — about 300 to 450 on Starter's 3,000, or 900 to 1,350 on Creator's 9,000. If a test burns through the allowance, top-up packs never expire and stack on top of plan credits, so burst experiments do not have to distort next month's budget.
