System Prompt Variables

GenAI Studio provides 5 predefined system prompt variables for users to quickly access:

• time: The system will automatically convert this variable into the current time, e.g., 1:34:26 PM.
• date: The system will automatically convert this variable into the current date, e.g., April 17, 2026.
• datetime: The system will automatically convert this variable into the current date and time, e.g., Friday, April 17, 2026 1:36 PM.
• user.name: The system will automatically convert this variable into the user's name.
• user.bio: The system will automatically convert this variable into the user's bio.

To use these predefined variables in the system prompt, simply place the variable name inside a pair of curly braces ({ }), for example, {user.name} will be replaced with the user's name.

In addition to the predefined system variables, users can define their own variables for commonly used system prompts according to their needs. Once saved, they can be used directly in the system prompts.
