Separating the confirmed from the unconfirmed makes the weight of this update clearer. What is confirmed: the leaderboard now labels derived models and allows hiding them; derived models display their base model's logo next to their name; users can choose to rank only base models; the announcement post shows 7,245 views.
What belongs to the organization's own claims and awaits external verification: the number of derived models is "growing"; in the top five, Utopai X and MiniMax H3 Max are based on MiniMax H3; derived models may be clearly better or worse than base models in specific capabilities; they often differ in pricing, speed, and availability. The source is only an announcement post and its comments, with no complete leaderboard or methodology document, and no complete ranking or scoring data for AA-Video-T2V v2.0.
There are also several dimensions the source does not cover at all: whether the growth trend in the number of derived models is supported by data (the source only says "growing"); whether the labeling feature covers Artificial Analysis's other leaderboards; and information about the developer or publisher of MiniMax H3. These gaps mean that what can currently be confirmed is that "the labeling mechanism has launched," not that "the derived-model ecosystem has been quantified."
