GPT Image 2.5 price on Sume: 1K, 1080p, 2K and 4K at low, medium, high

GPT Image 2.5 at the default high quality costs about $0.066 per 1024x1024 image on Sume, about $0.050 at 1920x1080, $0.069 at 2560x1440 and $0.125 at 3840x2160. Low quality is $0.006 to $0.014 per image and medium is $0.013 to $0.033. Sume bills the fal token rates times 1.25; fal's own per-image table is in the middle column.

Where the numbers come from

fal's GPT Image 2.5 page lists $30 per million output image tokens, $8 per million image input tokens and $5 per million text input tokens, plus a per-image table. Sume's image docs state the same rates and that an omitted quality defaults to high. The Sume figures below come from the repo's estimator for a minimal prompt, so they include a few text input tokens and are rounded up to $0.0001 before the margin; a long prompt adds a little more.

Notes for budgeting

Catalog quotes on Sume are shown in whole cents, rounded up, so a high 1024x1024 image appears as 7 cents. Reference images and masks add input tokens, and xhigh and max cost more; see xhigh vs max. Image size also changes price in a non-obvious way: portrait is cheaper than square.
