Stop Sequences

Sequenze di Stop

Stop sequences are strings that, while the model is generating, immediately halt output as soon as they are produced. You set them via the API to precisely control where the response must end, preventing the model from running on past what is needed. Example: in a dialogue format where each turn starts with "User:" and "AI:", you set stop = ["User:"] so the model, after writing the AI reply, stops before inventing the user's next turn too. Another use: stop at "\ \ " to get a single paragraph.

Definition

Use them when generating fixed-structure output, lists, dialogues, delimited fields, or to cut unwanted trailing text without post-processing. They are a technical control complementary to max tokens: stop sequences halt at a semantic delimiter, not a count.
