Krea 2 API pricing: references and moodboards vs Sume pricing

Krea 2 prices a generation by variant and input: Medium is $0.030 for text-to-image, $0.035 with style references and $0.040 with moodboards; Large is $0.060, $0.065 and $0.070. Sume has no Krea model in the catalog code I read; its prices come from GET /v1/images/models.

Krea facts are from its Krea 2 API overview; Sume facts are from Image models, read 2026-10-01.

What does each Krea 2 variant cost?

Do moodboards plus style references cost extra?

No. The page says combining them does not raise the price: you pay the moodboard rate, $0.040 for Medium or $0.070 for Large. At that rate 100 Large generations come to $7.00.

How does Sume show a price?

Through GET /v1/images/models, which lists models with pricing. The docs say the endpoint pricing line is the amount charged to your wallet, with Sume's margin already applied, and billing is all-or-nothing. They list reference images as one parameter, input_references, not as a price tier.

The code-defined catalog has ids such as grok-image and flux-2-pro and no Krea id, so a Krea price has no Sume line to compare to.

curl "https://api.sume.com/v1/images/models" \

How do I compare costs fairly?

Match output size, references and images per call, then multiply by volume. Related: Luma's per-reference price steps.
