Your deep-imager balance is a stack of credit batches — each with its own expiry — not one endless pool.
Spend what expires first. Check-in dies at midnight; packs last 30 days.
How long do different credit batches last?
Signup and paid plan credits last 30 days from the day they are added; daily check-in credits expire at the next midnight.
New accounts get 5 signup credits with that 30-day window. Buying Basic, Advanced, or Professional on pricing from $1/month adds another 30-day batch.
Rewards check-in adds 2 credits that must be used the same calendar day — see daily check-in credits. Expired batches drop out of the balance the workspace shows before generate.
Which batch does a generate spend first?
The earliest-expiring batch with remaining credits — then the next soonest — until the Generate cost is covered.
If you claimed check-in this morning and still have signup credits, a text to image run usually burns the check-in batch first because it expires sooner.
That is why the Generate button cost matters more than a raw total: the button tells you how many units leave the wallet; expiry tells you which units leave first. Read how credits work for live per-model rates.
- Claim check-in only when you will generate the same day.
- Keep quantity at 1 until the brief is proven.
- A failed run refunds to the original batches when the product marks failed.
Does image to image follow the same spend order?
Yes — image to image and text to image both deduct from the soonest-expiring valid batch.
Upload a reference in image to image and the same ledger rules apply. Mode does not change expiry or spend order.
For a cheap same-day spend of check-in credits, Nano Banana keeps the per-still cost low while you use what would otherwise expire at midnight.
What should you do before credits expire?
Generate a still you need, or stop claiming check-in until you have a brief — do not open pricing only to “save” same-day credits.
Thirty-day packs are for a month of work; midnight check-in is for today’s session. Typical still time is 30 seconds–2 minutes. Plans: Basic $1/month for 10 credits, Advanced $9.99 for 120, Professional $19.99 for 300.
