FLUX.2 pro price: $0.03 first megapixel on fal, $0.0375 listed on Sume

FLUX.2 [pro] costs $0.03 for the first output megapixel and $0.015 for each additional megapixel (rounded up) on fal, so 1024x1024 is $0.03 and 1920x1080 is $0.045. On Sume, black-forest-labs/flux.2-pro lists $0.03 per image and bills list x 1.25, which is $0.0375 at the catalog default size, before Sume's per-job round-up to the cent.

The two pricing models

fal prices by megapixel. Sume's catalog publishes one list price per image, so check the endpoints record for a larger frame rather than assuming that the price stays flat.

What fal lists as features

The fal page lists automatic prompt enhancement on by default, seed control, JPEG and PNG output, JSON structured prompts, HEX color codes and @ image referencing, and sizes of 1K, 2K and 2.3K. On Sume, the row lists 13 aspect ratios from 21:9 to 9:21, png, jpeg or webp, up to 4 images per call, and no seed field. A field that the row does not list returns 400.

The request below uses a ratio from the Sume list:

curl -s https://api.sume.com/v1/images \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"black-forest-labs/flux.2-pro","prompt":"matte bottle on a stone ledge, soft window light","aspect_ratio":"16:9"}'

Decide

• Direct to fal if you want seed control and the JSON prompt features documented on its page.
• Sume if you want one key, one job model and the shared credits with video and voice.
• Test one frame at your real size before you plan a batch budget.
