Anthropic Claude's tool-use responses use structured outputs so orchestration frameworks like LangChain can parse tool calls deterministically without regex fragility.
Instructor library is used by 1,500+ GitHub repos to extract structured Pydantic models from LLM responses - a medical-coding startup uses it to reliably extract ICD-10, CPT codes, and dates from clinical notes.
