Flex VMs is Shadeform’s virtualization and VM management layer for turning bare-metal GPU nodes into single-tenant virtual machines with full GPU passthrough and no overcommitment. Hardware owners can enroll nodes using a dedicated IPv4 address and SSH access, then offer capacity to AI teams through Shadeform’s marketplace. Providers can also list idle capacity through Spot, use Provider Priority for their own workloads, and reclaim nodes when needed. The platform includes utilization and revenue metrics, host-health monitoring, and an in-browser KVM console.
