  "method": "cutoff: the knowledge cutoff the lab itself states for the model, read on the page in source, as precisely as the lab gives it (YYYY-MM for a month, YYYY-MM-DD for a day; precision says which). For its four current Claude models Anthropic gives a reliable knowledge cutoff and a training data cutoff, and they are the same month. live_since: the day ArtificialWatch verified the model live on a public API. months_to_release: whole calendar months from the cutoff's month to the release month. Labs that publish no cutoff are listed in not_published with the pages checked, and get no rows; catalog dates are not used.",
