Shadeform has launched Flex VMs, a virtualization layer designed to turn bare-metal GPU nodes into single-tenant virtual machines that can be listed on Shadeform’s marketplace. The company says approved nodes can be enrolled in about 30 minutes, aiming to shorten the time it takes compute providers to bring capacity online.

Flex VMs is built for GPU cluster operators that want to resell underutilized capacity without converting their infrastructure into a traditional multi-tenant cloud. Each node runs single-tenant VMs with full GPU passthrough and no overcommit. Shadeform also says providers can pull nodes back at any time, and that “Provider Priority” lets providers run their own workloads on their nodes.

The onboarding flow starts with a hardware owner signing up, generating an enrollment key, and running a script to register a machine using its IP address and an SSH key. Shadeform reviews each submission, and once approved, the company says enrollment takes about 30 minutes. For operators used to longer procurement and sales cycles, the practical implication is straightforward: marketplace listing becomes closer to an operational task than a business-development process.

After onboarding, providers can make a node available for resale when it’s idle with what Shadeform describes as a single click. Listing on Shadeform’s “Spot” offering is optional. Shadeform estimates that offsetting idle time with Spot can reduce total contract value by up to 29%, and says its current roster of Flex VMs has achieved more than 95% utilization across Blackwell and Hopper series GPUs on the platform.

“A lot of platforms say they can resell your underutilized GPUs, but that’s usually a manual process on their end. We actually built the mechanism to make it self-serve: once your GPU is onboarded, the minute you don’t need it, you can make it available for reselling with the click of a button,” said Ronald Ding, CTO of Shadeform.
