Luma AI, a U.S.-based frontier AI startup focused on building multimodal general intelligence, has raised $900 million in a Series C funding round led by HUMAIN, a Public Investment Fund (PIF) company developing full-stack global AI solutions. The round also saw participation from AMD Ventures and existing backers Andreessen Horowitz, Amplify Partners, and Matrix Partners.
The new investment marks a significant milestone for Luma AI, which aims to build multimodal AGI capable of understanding, generating, and interacting with the physical world. The company says this funding will accelerate its work on large-scale World Models — foundational systems that learn from humanity’s digital footprint across video, audio, images, and language.
HUMAIN’s 2GW “Project Halo” Supercluster to Power Luma AI
As part of the partnership, Luma AI will become a major customer of HUMAIN, which is currently building Project Halo, a 2-gigawatt AI supercluster in Saudi Arabia. Once completed, it is expected to become one of the world’s largest and most advanced AI computing infrastructures.
According to HUMAIN, the massive compute capacity will enable training and deploying frontier multimodal models at unprecedented scale, helping unlock real-world applications across robotics, entertainment, gaming, advertising, and personalized education.
Aiming for a Quadrillion Tokens of Multimodal Training Data
Amit Jain, CEO and co-founder of Luma AI, emphasized the scale of compute and data needed to advance multimodal AGI:
“To create AI that can help humanity in the physical world and expand our understanding of the universe, we need systems that can learn from a quadrillion tokens of information — the collective digital memory of humanity. HUMAIN is deploying frontier compute infrastructure at impressive speed, and this is critical to achieving Luma AI’s mission.”
Jain added that Luma AI and HUMAIN are collaborating deeply across customized models, go-to-market strategies, and deployment, forming a full end-to-end value chain for multimodal AI.
HUMAIN: Building the Full AI Value Chain
Tareq Amin, CEO of HUMAIN, said the investment aligns with the company’s strategy of shaping the global AI ecosystem:
“We’re not only funding the next wave of AI — we’re building the full value chain that makes it possible. Luma AI is an exceptional frontier startup pushing the boundaries of multimodal world models, and their vision aligns with ours.”
With the new funding and access to HUMAIN’s supercluster, Luma AI plans to scale training on peta-scale multimodal datasets and deploy next-generation inference systems capable of serving these models globally in real time.
The company says such deep integration of algorithms, systems engineering, and compute scale is necessary to build AI systems that can understand, simulate, and interact with the real world at human-level complexity.
