Naming a model every time against having one
Neither entry has a default and the reasons are opposite. On one, every call names a model from a list where each line carries its own price, so nothing runs unasked. On the other, one house model appears on every plan, so there is nothing to choose between. As of 2026-09-22.
| On this point | fal | Pika |
|---|---|---|
| Number of purchasable models | Several, each with its own price | One, across every plan |
| What a request names | The model, every time | Nothing; there is one engine |
| Where variation lives | In the choice of model | In resolution and features |
| What a version change reaches | Only callers naming that model | Every plan simultaneously |
| Is the engine identifiable later | Yes, from the invoice | By name, though not by version |
Inclusion rule. Both cells on a row come from the entry's own priced pages. A model named in marketing but absent from every priced page does not count. Order. Number of models first, then what varies instead.
1Two kinds of nothing to default to
One entry has no default because choice is compulsory. The other has none because choice is impossible. A reader scanning for empty cells would treat those as the same finding, and they produce completely different exposures.
Compulsory choice spreads risk across whichever models a production named. No choice concentrates it on one line that everybody shares.
2Per-model billing records what a bundle hides
Where each model carries its own price, the invoice already says which engine produced what. On a single-model plan the engine is known by name and not by version, so a silent update leaves no trace on any document.
That makes the first entry easier to audit after the fact. The register keeps recommending exactly that record, and here it falls out of the billing arrangement.
3Blast radius differs by an order
A version change on a per-model list affects the callers who named that model. On a single-line menu it affects everybody on the same day, and there is no older generation listed to finish a season on.
Both entries publish no date and no successor. The succession reading for the single-line entry sets out what having nothing behind it means.
- How the meter worksVideo models are billed by output unit, per second or per video depending on the modelquoted from the page
