per second
- Clip length is chosen per request, from 4 to 15 seconds (default 6).
- When a reference video is supplied, the provider bills the input and output seconds together, so a clip costs more than the output length alone suggests.
- The first five reference images are free; each one beyond that carries a small flat surcharge, and reference audio is free.
- A reference audio clip sets the VOICE the dialogue is spoken in (2–15 seconds, alongside at least one reference image or video); its words are not replayed.

How model pricing works
Every AI model strikes a different balance between speed, answer quality and cost. Flagship models suit complex reasoning, long-document analysis and precise code generation, while lighter models cost considerably less for summarising, classification and short answers. The list above shows each model's rate broken down by input token, output token and cache, so you can estimate the cost of your workload before you start.
A token is the smallest unit of text a model processes; roughly speaking a thousand tokens is about 750 English words. The cost of a request is the sum of its input and output tokens, so shortening your prompt and capping the response length reduces cost directly. Some models have a second price tier for very long inputs, which reprices the entire request once it crosses a stated threshold.
