The decision, in plain words

For a solo builder at 50,000 images/month at standard quality (~1MP) and a $50.00/mo budget for the image API slot, Stability AI leads at 36% fit and $3250.00/mo. The two rules doing the work: ecosystem maturity (established — our estimate from ecosystem age, docs and hiring pool); batteries included (Bundles editing/inpainting — fewer services to glue at team size 1).

Honest weak spot of the pick: ~$3250/mo is 6500% of your $50/mo budget — over it.

Generated from the calculation above — every number traces to the sourced data; nothing here is written by an AI making things up.

Why Stability AI scores 36%

Budget fit (weight 30, our estimate) — ~$3250/mo is 6500% of your $50/mo budget — over it-30

Batteries included (weight 12, our estimate) — Bundles editing/inpainting — fewer services to glue at team size 1+4

Exit cost (weight 4, our estimate) — Open-weights model family — a self-hosting exit exists (license permitting)+2.4

Ecosystem maturity (weight 8, our estimate) — established — our estimate from ecosystem age, docs and hiring pool+8

Total (lines sum exactly)-15.6

Possible range −54…+54 (sum of active rule weights) · fit % = (total + max) / (2 × max)(-15.6 + 54) / 108 = 36%
