Tool Calling, Explained: How AI Agents Decide What to Do Next

# Tool Calling: How AI Actually Gets Things Done AI systems like ChatGPT can now do more than just talk—they can decide what actions to take and use other programs to complete tasks, like checking your calendar or pulling up information from a database. Think of it like giving an assistant a toolbox: instead of just answering questions, the AI can choose which tool to grab (a calculator, a search function, an email system) and use it to actually accomplish something for you. This is why modern AI feels more useful than just a smart chatbot—it can now take real steps to solve your problems.
