 "what": "Instructor gets reliable structured JSON out of LLMs. You define a Pydantic model, call `instructor.from_provider` with any major provider such as OpenAI, Anthropic, Google, Groq or local Ollama, and get back a validated, typed object, with automatic retries when validation fails.",
 "why": "14k stars, talked about in 2 AI sources we track",
 "language": "Python",
 "requirements": [
  "Python with pip, uv or poetry",
  "An API key for your provider, or a local Ollama install",
