AI image cost per image: Gemini, Luma, Ideogram and GPT Image lists

Per image, the lowest list prices read today are Gemini 3.1 Flash Lite Image at about $0.0336 for a 1K image, Luma Uni-1.1 at $0.0404 for 2K, and Ideogram 4.5 at $0.03 on low quality; the high-quality end runs from $0.134 for Gemini 3 Pro Image to $0.22 for Ideogram 4.5 high. What Sume charges is shown per endpoint by the Image API, and this post states vendor lists only.

The lists

Gemini and Luma rates are the vendors' own; Ideogram and GPT Image 2.5 are fal list rates quoted by Sume's docs.

How to read your Sume price

Sume's Image API docs state that endpoint pricing lines are the amount charged to your wallet with Sume's margin already applied, so cost_usd x n is what you pay. Read it from GET /v1/images/models/{id}/endpoints rather than computing from the lists above.

Budget 1,000 images by multiplying: at Gemini's ~$0.067 that is about $67 on the vendor list; at Luma's $0.0404, $40.40; at Ideogram medium, $60. These are vendor-list sums, not Sume quotes, and the GPT Image numbers exclude input tokens.
