Nebius joins PyTorch Foundation as Platinum member, gets a board seat
Nebius, the Amsterdam-based AI cloud company, has joined the PyTorch Foundation as a Platinum member, according to a foundation announcement. The membership comes with a seat on the Governing Board, which Nebius will fill with Ryan Hanrui Wang, its Senior Vice President of Applied AI.
- Nebius has joined the PyTorch Foundation as a Platinum member.
- The membership includes one seat on the Governing Board, filled by Ryan Hanrui Wang, SVP of Applied AI.
- Nebius plans to contribute to PyTorch and vLLM performance on the latest hardware platforms.
- Wang will also represent Nebius on the Technical Advisory Council (TAC).
- Nebius has long supported vLLM with compute, including multi-node work on DeepSeek R1.
What Nebius brings to the foundation
The PyTorch Foundation describes itself as the vendor-neutral home for the open source intelligence layer. Nebius, which is listed on Nasdaq (NASDAQ: NBIS) and headquartered in Amsterdam, says it is building a full-stack platform for developers and companies, covering data, model training and production deployment. It serves startups and enterprises building AI products, agents and services worldwide.
According to the announcement, startups and enterprises already use PyTorch to train and fine-tune models at scale on Nebius AI Cloud. The company has also long supported vLLM with compute for development, testing and benchmarking, including multi-node work on large models such as DeepSeek R1. Its Applied AI team contributes inference and post-training optimizations to open-source projects, and that open-source work has been incorporated into the PyTorch Ecosystem.
Plans as a Platinum member
As a Platinum member, Nebius plans to contribute to PyTorch and vLLM performance on the latest hardware platforms. It also intends to share what it learns from running inference and post-training at production scale.
Ryan Hanrui Wang said: "At Nebius, we believe the future of AI depends on a strong, connected ecosystem, from training to deployment." He added that the membership allows the company to collaborate more deeply with the community and contribute its expertise in high-performance infrastructure and applied AI.
Mark Collier, Executive Director of the PyTorch Foundation, said the strength of the ecosystem is "how we work together to tackle AI’s toughest scaling challenges." He said Nebius is using and advancing projects like vLLM and PyTorch to drive both high-throughput inference performance and large-scale model training.
Board seat and technical role
Platinum membership grants Nebius one seat on the PyTorch Foundation Governing Board. According to the foundation, the Board sets policy through its bylaws, mission and vision statements, and describes the overarching scope of foundation initiatives, technical vision and direction.
Wang leads inference, post-training and agentic systems at Nebius. He previously co-founded and served as CEO of Eigen AI, which Nebius acquired in 2026. He holds a Ph.D. in Computer Science from MIT, where he created the SpAtten sparse-attention framework and Hardware-Aware Transformers. The foundation says his open-source work has passed one million downloads and is part of the PyTorch Ecosystem, and that he is an MIT Technology Review Innovator Under 35. He will also represent Nebius on the Technical Advisory Council (TAC).
What it means for the ecosystem
The PyTorch Foundation is hosted by the Linux Foundation and supports the core PyTorch framework alongside projects including vLLM, DeepSpeed, Ray, Helion and Safetensors. For Nebius customers and PyTorch users, the announcement points to continued work on inference and training performance, with a cloud provider that runs these workloads in production taking a formal role in governance. The source does not give details on specific releases or timelines for the planned contributions.
