What is the difference between the System, User, and Assistant?
System
The System defines the AI’s program. It controls persona, behavior, limitations, and more. When interacting with Claude AI or ChatGPT, each model has a system prompt under the hood.
- For Claude AI (Anthropic), system prompts are publicly available (e.g., Claude Sonnet, Claude Opus).
- For ChatGPT (OpenAI), the system prompt is unofficially leaked but not officially published.
- In AirOps LLM steps, a custom System prompt must be defined to tailor AI behavior.
- Model selection varies by platform:
- ChatGPT uses ChatGPT4o.
- Claude AI uses Claude Sonnet 4 or Claude Opus 4.
- AirOps LLM steps allow selection of any supported model.
User
The User field captures the human’s message. Any text added here becomes the AI prompt. For example, entering “What is content engineering?” is treated as the User input.
Assistant
The Assistant field holds the AI’s response. It serves as a prompting technique to influence output quality, tone, and style, especially in long-form writing tasks.
- Assistant prompts are optional and typically used for advanced prompting techniques.
- User prompts are always required.
- System prompts may be optional or required depending on the task.
