Veo 3.1 holds the audio-sync niche while Runway anchors the marketer stack — multimodal video splits into specialist workflows around production targets
The multimodal video category has stratified by use case rather than capability. Veo 3.1 holds the realism + native-audio combination that production studios prefer. Runway's Gen-4 Turbo plus the reference-image control set anchors the marketer/brand-consistency workflow. LTX-2 Fast is the throughput option. Specialized verticals are absorbing the workflow rather than one generalist flagship dominating.
The specialization-by-vertical pattern matches what's happening in text models. Anthropic's Fable 5 ships as a long-form narrative specialist rather than a generalist; video is now bifurcating the same way. Veo 3.1's native-audio synchronization is the production-shop differentiator — audio-video sync at the model layer eliminates a major post-production step. Runway's reference-image + character-consistency stack is the brand-shop differentiator — marketers need character continuity across multiple generations, not single-shot maximum realism.
The leaderboard-and-product distinction matters. Happy Horse 1.0's top leaderboard position is impressive in the blind-arena vote, but it doesn't immediately displace Veo or Runway in production studio buying decisions — those buyers care about workflow integration, audio sync, reference-image controls, and editor toolchains that don't surface in a blind-vote arena. The benchmark + product split is now a permanent feature of multimodal evaluation.
