The model isn’t the agent. An LLM can decide what should happen next—but it can’t actually search the web, run code, call an API, or complete a task by itself. That’s where the AI harness comes in. It gives the model tools, executes its actions, tracks context, handles errors, and feeds the results back so the model can decide what to do next. LLM = the brain. Harness = what turns the brain into an agent. Once you understand harnesses, modern AI agents make a lot more sense. #AI #ArtificialIntelligence #AIAgents #LLM #MachineLearning
