OpenAI DevDay 2024 | Structured outputs for reliable applications
OpenAI. Walks through `strict: true`, the difference from old JSON mode, refusal handling, and how function calling and response-format schemas compose. Useful precisely because it describes the contract the API gives you, which is what the article's production patterns are built on top of.
AI Expert note
Just under our view bar but canonical — the team that shipped strict mode describing the API contract the article's production patterns are built on.
What you should get from this

Emory University Goizueta Business School faculty
The deeper, university-level counterpart to our beginner HubSpot marketing pick — Emory's business-school treatment goes past 'how to prompt' into training generative models for brand-specific output, the purchase-funnel economics of AI-generated content, and a full module of genuine skepticism about when generative AI is and isn't worth using in marketing.
