How do Martini credits work?
Short answer
Credits are the unit Martini uses to bill every AI generation — image, video, audio, voice, and text model calls. Your account holds two balances: a monthly subscription quota that resets on your billing date, and wallet top-ups you purchase as needed. Each model call deducts from the subscription quota first, then from the wallet.
What credits are spent on
Every call to an AI model on Martini deducts credits at the moment the request is sent to the provider. That includes image generation, video generation, audio and voiceover synthesis, lip-sync, character consistency runs, transcription, and any text or script model invoked from a node. Manual edits to a node, dragging connections on the canvas, and saving projects are free — only model calls draw down credits.
Credit cost varies by model, resolution, and duration. A 1080p Veo clip costs more credits than a 720p Hailuo clip of the same length. A six-second video costs more than a two-second video on the same model. The exact cost is shown on each node before you run it, so you can see what a generation will cost in advance and adjust resolution or duration if you want to spend less.
Subscription quota vs wallet top-ups
Your subscription plan grants a monthly credit quota. That quota resets on your billing date each month and does not roll over — unused subscription credits are gone at the cycle reset. Pause or cancel mid-cycle and the remaining subscription credits stay usable until the period ends.
Wallet top-ups are credits you buy on top of your plan. They are applied to your account immediately and do not expire. Wallet credits are spent only after your monthly subscription quota is fully drawn, so you do not lose top-ups by running heavy generations early in the month. If you cancel your subscription, wallet credits remain in your account.
Where to see your balance and usage
Open Settings, then Billing, to see both balances side by side: the remaining subscription quota for the current period, the wallet balance, and the date your subscription credits next reset. The same page lists recent generations with the model used and credits spent per run, so you can audit what's costing the most.
Workspaces have their own pooled credit balance that members spend against, separate from any personal balance you hold. If you belong to a workspace, switching the active workspace in the top bar changes which balance is being drawn down for the next generation.
Examples
- A 5-second 720p Hailuo video clip costs fewer credits than a 5-second 1080p Veo clip.
- A 4-image batch on the same model costs roughly four times one image at the same settings.
- Increasing video duration from 4 to 8 seconds roughly doubles the credit cost on most models.
- Lip-sync runs charge separately from the underlying video generation that produced the clip.
- Re-running a node with the same prompt and seed still costs credits — the model is invoked again.
Edge cases
- If a generation fails on the provider side, credits are restored — see the failed-generation refunds article.
- Subscription credits expire at the billing reset; wallet credits do not.
- Workspace balances are separate from personal balances and are pooled across members.
What to do next
- Open Settings, then Billing to view your current quota, wallet balance, and reset date.
- Check the credit estimate shown on a node before clicking Run if you are budget-conscious.
- Buy a wallet top-up from the Billing page if you expect a heavy month and want a buffer past the reset.
