Why structure matters
Free-form text works for an assistant reply. It is a poor interface for updating a CRM record, generating a support ticket or driving an automated workflow. Use a schema that specifies required fields, allowed values and error states.
{
"intent": "support_request",
"priority": "normal",
"summary": "Customer requests a receipt",
"needs_human_review": false
}
Example output only, not a real model response.
Reliability checklist
- Prefer provider-supported constrained generation or schema features where available.
- Validate every result in application code; do not assume the provider guarantee covers your business rules.
- Treat tool arguments and structured outputs as untrusted until checked.
- Allow a limited repair attempt for malformed data, with a clear fallback.
- Retain a versioned schema and test against edge cases.
Keep the user in control
Structured generation does not authorize a real-world action. Review permissions and confirmation requirements separately from output formatting.
Explore agent tools and model comparison criteria.
