Ideogram 4.5 blended cost per image: a 70/20/10 quality mix on Sume
A 70/20/10 low, medium, high mix of Ideogram 4.5 averages $0.0688 an image on Sume, $0.0725 with the fee. Three mixes and a 1,000-image bill.

Ideogram 4.5 does not charge by pixels. On Sume the quality parameter (low, medium or high, default medium) sets the price, and resolution of 1K or 2K does not change it. So the number to budget with is not one price per image but a blended price for your mix of drafts and finals.
Sume prices every job at the vendor list price × 1.25, then adds a 5.5% fee on that result, so $1.00 of list becomes $1.31875 (how the formula works). The tables below show both the catalog price (list × 1.25) and the all-in figure with the fee.
The three tiers
The fal list prices behind Sume's Ideogram 4.5 row are $0.03 (low), $0.06 (medium) and $0.22 (high) per image, as written in Sume's Image API docs.
| Quality | Vendor list | Sume catalog (x 1.25) | All-in (with 5.5% fee) |
|---|---|---|---|
| low | $0.03 | $0.0375 | $0.039562 |
| medium | $0.06 | $0.075 | $0.079125 |
| high | $0.22 | $0.275 | $0.290125 |
Three mixes, one blended price
Weight each tier by the share of images you generate at it. The blend is the weighted sum of list prices, then multiplied once.
| Mix | % low/medium/high | Blended, catalog | Blended, all-in | 1,000 images, all-in |
|---|---|---|---|---|
| Draft-heavy | 70/20/10 | $0.06875 | $0.072531 | $72.53 |
| Balanced | 40/40/20 | $0.10 | $0.1055 | $105.50 |
| Finals-heavy | 10/30/60 | $0.19125 | $0.201769 | $201.77 |
Reading the result
A draft-heavy mix (70/20/10) averages $0.06875 an image at catalog price: the 10% of high renders add $0.0275 of that, more than the 70% of low renders ($0.02625). The high tier is 7.3x the low tier, so a finals-heavy mix costs about 2.8x the draft-heavy one.
See when a $0.22 high render pays for the quality decision itself.
