More questions
How much does an 8-second Veo 3.1 Fast video cost?
On UberLLM, $1.02 at 720p with sound ($0.1275 per second × 8). The same clip costs $1.20 at fal.ai, $0.30 at kie.ai, $1.20 at Replicate and $0.80 at Google Vertex AI. Veo 3.1 Fast makes clips of 4, 6 or 8 seconds.
Is kie.ai cheaper than UberLLM for Veo 3.1?
Yes. kie.ai's price per second is lower on 8 of the 8 clips both sell; UberLLM's is lower on 0, counting its 5.5% card fee. kie.ai prices some clips per video: the table divides that price by the clip length shown under it, and where kie.ai sells several lengths (or one price for several), the lowest price per second is used, so kie.ai is never overstated.
How is the UberLLM Veo 3.1 price set?
The video runs on Fal, and the price is fal.ai's own price for the same clip less the discount of the cheapest Fal seller live when this page was built (15% under fal.ai): seconds × the rate for the resolution and sound you ask for. If that seller turns a job down, a dearer one makes it at its own price, never more than estimated_cost_usd on the reply.
