Higgsfield Soul price per image: an account estimate, what Sume bills

Searches for a Higgsfield Soul price per image tend to end at credits, not dollars. Per Sume's own pricing source notes, Higgsfield publishes no public USD tariff for Soul 2. The list Sume uses is an authenticated estimate request for higgsfield-ai/soul/v2/standard made for the Sume account on 2026-09-17: 0.050 credits, valued at $0.004 per image at 720p, and 0.090 credits, $0.006 at 1080p.

That makes the Sume price a derived number, and the repo says so: it must be re-stamped when the estimate moves. What you pay is that list times 1.25.

What Sume bills

Prices here are Sume's list-times-1.25 figures. The catalog states the billable formula as "list × 1.25 → ceil usd cents", so treat the dollar amounts as the pre-rounding value and read the exact charge from billable_amount_usd_micros in the submit envelope. Failed or cancelled generations are not billed.

What to know before you build on it

Soul is text-to-image only on Sume: input_references is not accepted. n is 1 or 4 only, not 1 to 4, and resolution is 720p or 1080p. Its seven aspect ratios are 1:1, 16:9, 9:16, 4:3, 3:4, 3:2 and 2:3 (default 4:3). It returns PNG chosen by the provider, so output_format is not advertised for it.

At half a cent, a batch of four at 720p is two cents. Because the list is an estimate rather than a published tariff, put a budget guard around it: read GET /v1/images/models/higgsfield/soul/endpoints for the current pricing line before a large run, and treat the figure above as the 2026-10-07 reading.
