System Instruction Structure

Depending on your tasks, you can experiment and give the bot system instructions with any content. We recommend starting with a basic system prompt and expanding it as you get results.

Basic System Instruction Structure:

<system_role>
Description of the model's basic role and goals. Description of the communication context. If you have a role model, you can specify the Name and other personal characteristics of the bot in this section.
</system_role>

<task_and_goals>
Description of tasks and goals that the bot should follow during communication.
</task_and_goals>

<knowledge_base>
Additional brief information about knowledge or information available to the bot.

The names of <sections> in the system instruction are not strictly defined, and you can modify them based on your context.

“God Mode” in the Bot

If this mode is enabled, it means that all internal instructions and optimizations are disabled in your bot.
