$7.30 image wallet: how many images each Sume row buys

A $7.30 balance buys 294 images on GPT Image 2.5 at low quality, 166 on Seedream 5 Lite, 73 on Nano Banana 2.1 at 1K, 32 on GPT Image 2.5 at high quality and 4K, or 324 background removals, using Sume's per-image prices as of 2026-10-09. The counts below are whole images only, since Sume bills each completed image in full.

$7.30 is an arbitrary top-up size on purpose. Round budgets like $5 and $10 already have pages. This one shows how the division works, so you can do it for your own balance.

Images per $7.30, row by row

Each count is the balance divided by the per-image price, rounded down. The last column is what is left over, which is often enough for one more cheap image on a different row.

How to read the table

The spread from top to bottom is large. A $7.30 balance makes 294 low-quality GPT Image 2.5 drafts, but only 19 Nano Banana Pro images at 4K. Image upscale is the steepest line, at $0.20, so 36 upscales use up the wallet, while 324 background removals fit in the same money.

A two-stage plan beats a single row. Generate 100 drafts on GPT Image 2.5 low for $2.475, which leaves $4.825. That buys 24 Nano Banana 2.1 images at 2K ($3.60), and the remaining $1.225 pays for 6 upscales ($1.20). The plan uses $7.275 of the $7.30 and delivers 100 drafts, 24 finals and 6 upscaled heroes.

Check your balance against the quote

Sume checks your balance when you submit and rounds the hold up to whole cents. A GPT Image 2.5 medium 2K image lists at $0.055625, and the hold is 6 cents. Keep a small cushion above the count you plan to run. The Image API returns the billed amount in usage.cost, and failed or cancelled jobs are not billed, so a retry after a failure does not double the charge.

To see the prices live, call GET /v1/images/models for the image rows and the public catalog for the fixed-price tools. The Image API docs explain n, which multiplies the per-image price: a call with n: 4 on Seedream 5 Lite costs $0.175.
