Model Fingerprint

Definitions

1. An identifier or signature used to distinguish a specific model build, configuration, or inference environment from others. Model fingerprints help trace subtle behavior changes that may not be obvious from the model name alone.

   In plain English: A unique identifier that helps tell one specific model version or build apart from others.

   Example: "They logged the model fingerprint with every response so regressions could be tied back to the exact serving configuration."
