On day three of WAIC 2026 (July 19), Kunlun Wanwei's Skywork is set to release four models in a single forum session: the Matrix-3.5 world model, the SkyReels v4.5 video model, the Mureka v9.5 music model, and the Riemann-1.0 robot model — corresponding to the four dimensions of "vision, sound, motion, environment", and together forming the complete mosaic of its "full-modality + embodied intelligence" strategy. The headline Matrix-3.5's key innovation is the joint training of "next-frame state generation" with "action generation" — 5B parameters, 720P@40FPS real-time interaction, and a fully re-architected long-term memory structure. In parallel, Skywork has accumulated 5M+ high-quality video clips, 10K+ training hours, and 1,200+ game scenarios, with three automated data pipelines (UE5 autonomous exploration + cross-game automation + open-source video mining) that compress physics-causal annotation to engineering-grade quality. This release marks the upgrade of the world model from "predict the next frame" to "joint state-action understanding and generation", laying the foundation for subsequent robot control, autonomous driving simulation, and general-agent training.
