Contributions
How Stale Is Your AI? lists release dates and documented training cutoffs separately, links each model to a provider source and offers the same data as JSON. Missing cutoff evidence stays blank. The distinction helps readers avoid treating a newly released model as proof of newly learned facts. Its counters describe elapsed time from recorded dates; they do not measure the quality of a model’s knowledge or whether an answer has used fresh web sources.[2]

A sourced model-date reference with a machine-readable data file and explicit missing-cutoff states.
Compare one model’s release date, cutoff and linked provider document. No coding is needed; developers can inspect the JSON data while keeping date freshness separate from answer accuracy.
