Agentic Loops with Tool Use
This lesson covers building agentic loops with tool use that let an LLM perform actions.
Like an assistant who can search Google and send emails — an agentic loop gives the AI real tools to act in the world, not just talk.
- Agentic loop
- A think→act→observe loop in which the LLM calls tools and reacts to their results.
- Tool use
- The LLM's ability to request execution of external functions while generating a response.
- MAX_ITERATIONS
- A guard that caps the number of loop iterations to prevent infinite loops.
- Parallel tool execution
- Running multiple tools simultaneously to save time.
