What is an AI function?
An AI function is a model call expressed in the schema — caption, transcribe, generate — rather than a separate pipeline product.
Updated · Part of What is a computed column?
How it works
- The call is an expression on a column.
- Inputs are other columns.
- The output is stored and reusable.
What it is not
It is not a chain of model calls with no stored outputs.
AI function: this, and the thing it is confused with
| This | Not this | |
|---|---|---|
| Lives | On the row | In a notebook cell |
| Rerun | When inputs change | Every request |
| Output | A column | A response you forget to save |
