So far, we’ve learned how to give instructions (Prompts) and get responses (Models). But there’s a problem: AI loves to talk. If you ask for a list of three cities, it might give you a whole paragraph explaining why those cities are great. If you’re building an app, you don’t want a paragraph; you want a Python list or a JSON object. Today, we learn how to "extract" exactly what we need using Output Parsers . 🧐 Why do we need Parsers? When you call an LLM in LangChain, it doesn't return a simple string. It returns an AIMessage object that contains the text, metadata, and token usage.
