The decision, in plain words

For a solo builder at 300 seconds of video/month and a $30.00/mo budget for the video generation API slot, Wan 2.5 (fal) leads at 84% fit and $15.00/mo. The two rules doing the work: budget fit (~$15/mo is 50% of your $30/mo budget); exit cost (Model-hosted API — prompts port, but exact look/quality doesn't transfer between models).

Kling 2.5 Turbo Pro (fal) runs close (77% fit, $21.00/mo). It takes the lead if ~$21/mo is 70% of your $30/mo budget matters more to you than the current weights assume.

Honest weak spot of the pick: growing — our estimate from ecosystem age, docs and hiring pool.

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

Why Wan 2.5 (fal) scores 84%

Budget fit (weight 30, our estimate) — ~$15/mo is 50% of your $30/mo budget+30
Exit cost (weight 4, our estimate) — Model-hosted API — prompts port, but exact look/quality doesn't transfer between models+0
Ecosystem maturity (weight 8, our estimate) — growing — our estimate from ecosystem age, docs and hiring pool-1.6
Total (lines sum exactly)28.4
Possible range −42…+42 (sum of active rule weights) · fit % = (total + max) / (2 × max)(28.4 + 42) / 84 = 84%
