Agentic systems: Model, tools, memory, and results form the core loop

An agentic system is composed of four key components: a model, tools, memory, and results, all interconnected in a loop. The model acts as the 'brain,' and the strategy should focus on optimizing the system around it rather than the model itself. This involves selecting the smallest, fastest, and cheapest model capable of performing the task and designing the system for easy model swapping. A common pattern is to use a powerful model like Claude Opus as an orchestrator and a smaller model like Claude Haiku for sub-agents, routing tasks by difficulty to manage costs and performance. AI

IMPACT Provides a framework for building more efficient and cost-effective AI agents by optimizing system design around interchangeable models.
