H3 Turbo is the free model. The grant is 36 credits, not an unlimited render.
A silent 5 second H3 clip at 480p costs 12 credits. Three of those fit in the signup grant. Ten seconds doubles the price, 720p is one and a half times, and audio adds 15.
Seedance 2 and Seedance 2.5 stay on a paid plan. Kling 可灵 is not billed because it is not connected.
