Notre classement
Structured outputs — JSON, XML, YAML — look simple and are not. Models that are strong at prose can still fail to emit valid JSON under pressure. We weight JSON-mode support and schema adherence, then price; for agentic pipelines JSON reliability is often a bigger efficiency lever than raw reasoning.

Field notes
Always send a schema. Most modern models support a constrained output mode.
Validate server-side. Never trust the model to handle `null` vs. `undefined` correctly.
If you see repeated schema violations, switch to function-calling rather than free-form JSON.
