Video generation startup Luma AI secured $900 million in funding led by Humain, backed by Saudi Arabia’s PIF, valuing Luma AI at over $4 billion. Luma AI pioneers multimodal “world models” and claims its Ray3 surpasses OpenAI’s Sora 2 in performance. Humain and Luma AI are collaborating on Project Halo, a 2-gigawatt AI supercluster in Saudi Arabia. The partnership includes the Humain Create initiative, developing sovereign AI models trained on regional data. Luma AI is also addressing copyright concerns and data bias in AI models.

At CVPR 2025, Kuaishou’s Kling AI division presented advancements in video generation and world model research. Their work focuses on improving model architectures, enhancing user control, establishing robust evaluation methods, and developing multimodal understanding. Key innovations include efficient scaling laws, novel Mixture of Experts architectures, a unified framework for spatiotemporal control, and frameworks for interactive and controllable video creation. The team’s research, highlighted across seven papers, aims to significantly advance video creation capabilities.

Alibaba open-sourced its modular Wan2.1-VACE video generation model (1.3B/14B parameters), featuring multimodal input support (text, images, video clips) and Lego-like customizable modules. The lightweight 1.3B version runs on consumer GPUs, democratizing AI video creation. Released on GitHub/Hugging Face, it has gained 330K+ downloads and 11K+ stars, becoming a leading open-source video generation framework.
