Structure prompts

How you structure a prompt can affect the model's ability to parse the information in the prompt. It also helps the model correctly interpret how to use the given information. To give structure to a prompt, you can use prefixes or XML tags to delimit different parts or components of a prompt.

Use prefixes to structure simple prompts

A prefix is a word or phrase followed by a colon to label the information in a prompt. In the following example, "TASK:, "CLASSES:," and "OBJECTS:" are the prefixes.

Prompt:

TASK:
Classify the OBJECTS.

CLASSES:
- Large
- Small
OBJECTS:
- Rhino
- Mouse
- Snail
- Elephant

Response:

- Rhino: Large
- Mouse: Small
- Snail: Small
- Elephant: Large

Use XML and other delimiters to structure complex prompts

For complex prompts, use XML and other delimiters to separate components of a prompt. You can use BEGIN and END or {} section delimiters for complex and lengthy prompt components to clearly distinguish them from the actual instructions.
