Luma AI announced it has raised $900 million in Series C funding. The round was led by HUMAIN, a PIF company focused on full-stack AI solutions. AMD Ventures, Andreessen Horowitz, Amplify Partners, and Matrix Partners also participated.

The investment marks a milestone in Luma AI’s mission to build multimodal general intelligence. The company aims to develop AI systems that generate, understand, and operate in the physical world. Luma AI will become a customer of HUMAIN as the company builds Project Halo, a 2-gigawatt AI supercluster in Saudi Arabia. Officials reported that the project will be among the world’s largest compute infrastructure buildouts.

The announcement was made in Washington, D.C., at the U.S.-Saudi Investment Forum during the visit of Crown Prince HRH Mohammed bin Salman Al-Saud. Both companies revealed a joint roadmap to advance multimodal intelligence on a global scale.

This new funding will accelerate Luma AI’s work on large-scale World Models. These models go beyond LLMs and learn from global digital data across video, audio, and language. The systems will support products in HUMAIN Create across robotics, entertainment, advertising, gaming, and personalized education.

Amit Jain, CEO and co-founder of Luma AI, said the company aims to train AI systems using data equivalent to a quadrillion tokens. He noted that HUMAIN is deploying compute infrastructure at rapid speed, enabling Luma AI to scale end-to-end multimodal capabilities.

Tareq Amin, CEO of HUMAIN, said the partnership reflects its strategy to build a full value chain for frontier AI. He added that the 2-gigawatt supercluster positions both companies to train and deploy multimodal models globally.

The supercluster will also include next-generation inference systems designed for real-time global deployment. This infrastructure is expected to support peta-scale multimodal data, which is up to 10,000 times more than current frontier LLMs.

Luma AI’s flagship model, Ray3, is already being used in studios, agencies, and brands. It is also embedded within Adobe’s global products. With the new funding, Luma AI plans to expand into simulation, design, and robotics.

Officials reported that Luma AI was the first set of models launched under HUMAIN Create, a regional initiative developing sovereign AI for the Arabic world. These models aim to support cultural context, linguistic diversity, and regional identity.
