You Don't Need LangChain — Build an AI Agent in 50 Lines of Python
Many developers tend to install LangChain and its numerous dependencies when trying to build an AI agent, often spending excessive time reading documentation, which leads to increased code complexity and line count. In reality, a simple AI agent can be built without relying on frameworks, using just 50 lines of concise Python code. This approach not only reduces code complexity but also allows developers to focus more on functionality rather than dealing with cumbersome dependencies.
