Output Contracts: Catch a Model Swap Before Downstream Systems Do
Structured outputs fix the shape of a model's answer, not its meaning: a two-layer contract between a Foundry model and the systems that consume it.

Structured outputs fix the shape of a model's answer, not its meaning: a two-layer contract between a Foundry model and the systems that consume it.
For even stricter control, use the structured outputs feature with a JSON schema. JSON mode transforms LLMs from conversational tools into reliable data…
JSON mode guarantees the model outputs valid JSON, though you still need to specify the schema in your prompt.
Structured outputs eliminate parsing errors. Add business validation for semantic correctness - the schema ensures format, you ensure meaning.
Structured outputs enable reliable integration of LLM capabilities into data pipelines.
Where GPT-4o vision helps data teams read charts and dashboard screenshots, what it gets wrong, what each image costs, and how to check its numbers in code.
Use GPT-4o structured outputs to draft a star schema from requirements, check it with plain code, and generate Fabric Warehouse DDL that respects its limits.
Which prompt techniques still earn their place on Azure OpenAI in January 2025, which moved into the API, and which now work against reasoning models like o1.
