Description

The structure description will appear here.

Apparent meaning, not a schema. The model infers what fields probably mean from their names and values; a 1.5B model gets the obvious ones right but can misread domain-specific fields, so verify against the API documentation before building on it. Your payloads, IDs, and customer data are processed entirely on this device and never uploaded. Powered by the same private engine as the Browser SLM Lab.
