Luma AI secures $900 million to advance multimodal intelligence

Luma AI has raised $900 million in Series C funding to progress its development of multimodal AGI capable of operating in the physical world. The round is led by HUMAIN, a PIF company specialising in full-stack AI solutions, with participation from AMD Ventures and existing investors Andreessen Horowitz, Amplify Partners and Matrix Partners.

The investment accompanies a wide-ranging partnership under which Luma AI will become a core customer of HUMAIN’s Project Halo, a 2-gigawatt AI supercluster being built in Saudi Arabia. Project Halo is positioned as one of the world’s largest compute infrastructure developments and is designed to support next-generation multimodal systems that train on vast video, audio, image and language datasets.

The partnership was announced in Washington, D.C., at the U.S.–Saudi Investment Forum during the visit of Crown Prince HRH Mohammad bin Salman Al-Saud. Both companies outlined a joint roadmap focused on advancing large-scale World Models that move beyond current LLMs and enable new applications across robotics, entertainment, advertising, gaming and personalised education through HUMAIN Create.

Chief executive Amit Jain said the company aims to build systems capable of learning from a ‘quadrillion tokens’ across human digital memory and emphasised that HUMAIN’s rapid deployment of frontier compute is central to this ambition. Jain noted that the companies will collaborate on customised model development, commercial deployment and multimodal product integration.

HUMAIN chief executive Tareq Amin said the investment reflects the company’s strategy to build the full value chain required for multimodal intelligence. He described Luma AI as a frontier startup with strong research velocity and the ability to commercialise foundational work at scale.

The 2-gigawatt cluster will include next-generation inference systems to serve multimodal models globally. Luma AI’s flagship model, Ray3, is already used across studios, agencies and brands and is embedded in Adobe products. The new funding will support expansion into simulation, design and robotics, including continued work on HUMAIN Create to develop sovereign AI models tailored to the Arabic world.
