WHAT IS AN AI AGENT?
1 min read
An AI Agent is not a new AI model.
Put simply:
Model / LLM + Harness → AI Agent
The Model / LLM provides language and reasoning ability.
The Harness is the system layer that organizes how the model works. It can include:
- System Prompt;
- Context / Knowledge;
- Tool;
- Context / History;
- Runtime / orchestration;
- guardrails;
- verification.
On F68 AI, users mainly configure:
System Prompt · Context · Tool
while the runtime layer is operated by the platform behind the scenes.
An Agent is not defined only by the model it uses.
It is also defined by how the model is organized to do the work.
