title: "Style Prompting"

How can we constrain model outputs through prompting alone?
|
||
|
|
|
||
|
|
To contrain a model's response to fit the boundaries of our task, we can specify a style.
|
||
|
|
|
||
|
|
Stylistic constraints can include:
|
||
|
|
|
||
|
|
- **writing style**: write a *flowery* poem
|
||
|
|
- **tone**: write a *dramatic* poem
|
||
|
|
- **mood**: write a *happy* poem
|
||
|
|
- **genre**: write a *mystery* poem
|
||
|
|
|
||
|
|
