Is there a reliable way to detect when OpenAI silently updates the model behind an existing API version?

OpenAI model activity is surfacing — worth tracking for capability changes, ecosystem impact, and availability.
A developer observed a prompt's output shifting significantly after weeks of consistent behavior, suspecting an unannounced OpenAI model update behind the API version they were cal…
Had a prompt behave consistently for weeks, then output shape shifted, more hedging, different formatting, a constraint that used to be respected got softer, with zero changes on my end. Best guess is a model update happened behind the version I'm calling, but I have no actual way to confirm that versus just being wrong about what changed.
Is there a real way to detect this after the fact, changelogs, a version identifier returned somewhere in the response metadata, a status page that logs these updates with dates? Or is pinning to a specific dated model snapshot the only actual protection against this, with no way to retroactively confirm an unannounced shift happened on a snapshot that's supposed to be frozen?
