TMTPOST — HiDream.ai released vivago R1, claimed as the world’s first multimodal creative agent capable of generating and editing videos of unlimited length, during the WAIC 2026 conference on Monday. Unlike mainstream AI video tools limited to 15-30 second clips, vivago R1 leverages AgentOS orchestration and multi-agent collaboration to handle full workflows—from task comprehension and storyboarding to coherent long-form output—with an 85% commercial delivery success rate. The debut addresses a critical bottleneck in China’s exploding generative AI market, where content creators and enterprises demand production-ready tools that overcome short-clip constraints for advertising, film, and digital media applications. As competition intensifies among domestic multimodal startups, breakthroughs in sustained reasoning and workflow integration could accelerate adoption and help HiDream.ai capture share in the shift toward agent-driven creative infrastructure.
