About LLM Agents

LLM Agents is a small library for building agents controlled by large language models, heavily inspired by langchain. It was written to show the core parts of a simple agent in very few lines of code. The agent cycles through Thought, Action and Observation, adding new information to the prompt until it can give a final answer.
