DECISION / USE

Why it matters

Use it when an extraction pipeline needs structured output plus visible evidence linking each value to the source text.

CAUTION / LIMITS

What to check first

Grounding indicates where returned text appears, not that every inferred claim is correct; cloud providers require keys and local-provider quality varies.
