It is often explained more by what it is not: it is not the language model itself.\u003C\u002Fp>\n\u003Ch2>Why the model alone is not enough\u003C\u002Fh2>\n\u003Cp>According to heise online, LLMs are practically never used directly. The source describes them as pure text-completion engines, and only very few tasks can be meaningfully handled by a system that simply continues a text without guidance.\u003C\u002Fp>\n\u003Ch2>What a harness covers according to the source\u003C\u002Fh2>\n\u003Cp>To turn an LLM into a chatbot, a coding agent, a security scanner or a personal assistant, heise online says a bundle of instructions, configurations and auxiliary programs is needed. These are meant to provide context, enforce security guarantees, evaluate whether a task was completed successfully, and allow the model to interact with other programs. Taken together, the source calls this a harness when the term is understood broadly.\u003C\u002Fp>\n\u003Ch2>Classification\u003C\u002Fh2>\n\u003Cp>As an interpretation: for decision-makers, the term is mainly useful as a reminder that the performance and risk of an AI agent do not depend on the model alone, but on the scaffolding around it.
