Scope & Deduplication Note
This roundup covers the "with-api-in-specs" selection only; it does not duplicate existing research roundups on AiRecMark, which use different member sets or criteria. Rankings derive solely from recorded archive scores — see the comparisons hub for every dossier, and rankings for full leaderboards.
