MiniMax H3 vs Seedance 2.5: Real-world Tests and Public Blind Test Favor H3
Released on July 31, MiniMax H3 and ByteDance's Seedance 2.5 sparked discussions about the gap between paper specs and real-world performance. Multiple real-world tests and a public blind test showed MiniMax H3 outperforming Seedance 2.5, offering a more grounded perspective for model selection.
Confirmed
- Release and specs: Both models were released on July 31. Seedance 2.5 is marketed for generating single 30-second videos.
- Technology and cost: According to @eyishazyer, MiniMax H3 uses H3-VAE compression, offering better cost-effectiveness for vertical short-video generation when requirements are clear.
- Real-world tests: @ZabihullahAtal tested with identical complex prompts, confirming H3's better prompt adherence and detail fidelity (e.g., 'driver breaking windshield' and 'river turning muddy in rain'). @socialwithaayan recommends H3 for immediate usable output, while Seedance 2.5 shows potential. Developer @LudovicCreator tested French dialogue generation in Dreamina with Runway's Seed Audio.
- Public blind test: @葬AI's memebench collected 50 popular memes from Bilibili and Douyin, invited 400 public users (including college students and internet cafe users) for pairwise blind voting with Elo rating, showing MiniMax H3 beating Seedance 2.5, contradicting some researchers' conclusions.
Unconfirmed
- The specific provenance of benchmark data is still being traced; @eyishazyer and @SimplyAnnisa say they have obtained actual benchmark data and are verifying each number, warning against being fooled by paper specs.
Why it matters
- Video model evaluation is often dominated by a few researchers; memebench breaks this limitation, providing a more grounded reference for model selection.
