Throughout this evolution, one fundamental technical challenge has persisted: <strong>how to make LLM outputs reliably parseable by programs.</strong></p> <p>Traditional LLM output is free-form text, forcing developers to use fragile approaches like regex and string matching to extract information. Structured Output and Function Calling (Tool Use) technologies have completely changed this paradigm.</p>
