Lightning AI, the company behind PyTorch Lightning and a leading platform for building and running AI applications, has completed its merger with Voltage Park, a large-scale GPU infrastructure provider. The combined entity, operating under the Lightning AI name, creates the first purpose-built AI cloud that integrates AI-native software with on-demand, high-performance GPU compute in a unified platform.
Traditional clouds like AWS were designed for CPU-based workloads (websites, services), not GPU-heavy AI tasks such as multi-node training, large-scale inference, and data preparation. This mismatch has led to reliance on dozens of specialized tools, creating procurement complexity, integration challenges, and high costs.
Lightning AI addresses this by building a cloud specifically for the generative AI era. Teams access GPUs, train models, deploy them into production, run inference at scale, and manage everything through a single interface—without stitching together disparate vendors or tools.
“Imagine instead of using an iPhone, having to carry a separate calculator, flashlight, radio, and more - that’s where AI tooling is today,” said William Falcon, founder and CEO of Lightning AI.
“The next phase of AI will be won by teams that control the entire stack,” said Timo Mertens, CTO of Cantina Labs. “Model performance, cost efficiency, and iteration speed increasingly depend on tight integration between the platform, deep optimization expertise, and owned compute. What’s compelling about this combination is that it brings those layers together into a single, cohesive system.”
“This puts us in a category that didn’t previously exist,” said Saurabh Giri, former CPTO of Voltage Park and now CPTO of Lightning AI. “Most neoclouds sell raw GPU capacity without a deep software stack. Most AI platforms depend on third-party clouds underneath. We’re software-first and infrastructure-native, and designed end-to-end for AI workloads.”
