What does research say about: Function calling eliminates output parsing failures for structured data?

OpenAI's function calling achieves 99.5% schema adherence vs 82% for text-based JSON extraction — a 17.5 percentage point improvement in parse reliability. (Source: OpenAI, 'Function Calling and Structured Outputs' documentation, 2024). Function calling forces the model to fill a pre-defined schema rather than generating free-form text, eliminating the need for brittle regex parsing.
