Keep your keys safe
These keys live in this browser's storage and go straight to the provider you picked — there is no server of ours in between, so we never see them. That also means anyone with access to this browser profile can read them. Use your own device, set a spending limit with your provider, and revoke a key you've stopped using. Every render bills your own account.
fal.ai
Runs the video model. Grab a key at fal.ai/dashboard/keys.
The director
An LLM reads your assets and their souls, then writes the video prompt.
Video model
All of these animate your stage image as the opening frame. Prices are estimates for your current 15s stage — they differ by more than 10×, so pick deliberately.
Resolution
The biggest single lever on price. Draft at the lowest, raise it once the scene is worth it.
What a render costs
Your 15s stage on MiniMax H3 Max Turbo bills 10s at $0.04/second — ≈$0.40 every time you press Make it alive.
The cheapest option here is Luma Ray 3.2 at ≈$0.30.
These are estimates, not quotes.
Prices were read from each model's fal page and are hard-coded here, so they go stale the moment fal changes them — and some models run temporary promotional rates. Before a big render, check the model's page and your fal usage dashboard. fal's number is the real one.
Cancelling a render also cancels the charge.
Length
How to reach a stage longer than one generation.
MiniMax H3 Max Turbo can do 10s in one call — switch to Chain to get past that.
