Background remover API prices: 5 options compared

On fal's list, Rembg Enhance is $0.006 per image, Pixelcut $0.016 per image and Bria RMBG 2.0 $0.018 per image, while BiRefNet v2 and fal's Imageutils Rembg are billed per compute second. Sume's rmbg_create MCP tool is a paid hosted tool whose price you read from the catalog.

The price table

Per image versus per compute second

A per-image price is predictable. A per-compute-second price depends on how long the model runs for each file, so you need one measured run before you can budget a batch.

Sume's `rmbg_create`

The hosted MCP lists rmbg_create among paid tools; it needs an idempotency_key, and under OAuth the session needs write scope. The docs call it the cutout tool. I cannot quote its price from the pages I read, so read it from the catalog or a dry_run before comparing.

How to compare fairly

Run the same ten images through each option, count edge failures on hair and glass, and record the cost per file. A cheap result you redo twice is not cheap.

• Same ten images across all options
• Check transparent PNG output on a checkerboard
• Note whether the licence suits commercial work
• Record cost per accepted file, not per call
