An agent harness is a piece of software that creates an operational environment for an AI model. This software component is fundamental to the development and function of AI agents, which combine AI models with these harnesses.
Initially applied in coding, agent harnesses are now central to various types of AI agents. Understanding how an agent harness works is key to comprehending the nature of an AI agent itself.
Unlike many AI models, end-users can own their own agent harnesses. This allows for greater control and customization of the AI agent's environment.
Users, such as software engineers, often interact with harnesses directly through applications like the Terminal. However, harnesses can also utilize diverse user interfaces, including chat apps like iMessage or email, to facilitate interaction with the AI model.
Regardless of the specific interface, agent harnesses generally perform four core functions. These functions provide the necessary structure and control for AI models to operate effectively as agents.
