No. Generations that error, time out or fail quality checks never burn your Credits. The hold releases itself automatically — no support ticket, no refund request, and a failure never consumes a kill from your allowance.
This is a permanent product rule, not a courtesy: failed takes don't cost you. If you see a charge you believe came from a failed render, that's a bug — message us with the approximate time of the render and we'll trace it in the ledger.

Try the same prompt on another model — model availability wobbles occasionally, and Elyum's routing usually works around it.
Very long or complex prompts can trip provider-side safety filters; a rephrase often gets through.
If a specific model fails repeatedly, tell us — we watch failure rates per model and act on them.
