Utopai X's No.2 video ranking questioned: post-training on MiniMax H3 under scrutiny
On Sept 30, 2026, Artificial Analysis's text-to-video blind-voting leaderboard placed Utopai Studios' Utopai X second worldwide with 1150 points, behind only Wan 3.0 and the top-ranked US model, prompting a wave of Chinese-language coverage calling it an "AI video dark horse" with a "proprietary custom model." The article says roughly 90% of that coverage ignored the leaderboard footnote "Utopai X (based on MiniMax H3)" — it is not trained from scratch but post-trained on MiniMax's open-source base with film-production data. It raises three questions: cost-effectiveness (base scored 1136 vs 1150, and no training compute or inference configuration has been disclosed), whether the fine-tuning can migrate to a new base model, and whether its iteration speed can match native models such as Seedance's continuous data flywheel.
It highlights that the ceiling for vertical post-training models sits with the base-model vendor, so a leaderboard rank is not an independent technical moat.

一场中文媒体报道乌龙,正在把一家美国创业公司推向“捧杀”的公关灾难。
2026年9月30日,美国独立评测机构Artificial Analysis发布文生视频模型排行榜,一家名不见经传的小模型Utopai X力压Seedance2.5、MiniMaxH3等一众热门选手位列全球第二,仅次于Wan 3.0,同时也是该榜排名最高的美国公司模型。
随后,中文媒体开始竞相报道,“全球最大独立AI原生影视公司”、“自研定制模型”、“AI视频榜黑马”,溢美之词跃然纸上。
