Higgsfield’s blog prices its own example on a $49 / 1,000-credit Plus plan ($1.23 per 5s at 720p); we use the plan prices on higgsfield.ai/pricing as last read. Runway app 10s/30s rates aren’t published. kie.ai and Higgsfield are listed first because ClipCost has affiliate links to them; numbers are the same either way.
