No official, commercial product page for a text-to-video product named "Narrative World Model" could be found. The only matching result is the "World Narrative Model (WNM)," an academic research framework (arXiv paper, project page at Shanghai Jiao Tong University) enabling controllable video generation by decoupling scene planning from pixel rendering. Since no pricing, platform, or licensing information nor a commercial vendor ("unknown") could be found, most requested product specifications cannot be substantiated.
