Gigawatt-scale AI compute, built and operated end to end
FluidStack designs and builds large AI data centers, including high-density campuses with significant per-site power capacity, rather than reselling capacity from other clouds.
Clusters are architected for large-scale model training and inference, with high-bandwidth interconnect and orchestration suitable for distributed workloads.
The company develops off-grid solar and recirculating closed-loop cooling, treating power and water efficiency as core engineering problems.
Smart hands, cluster provisioning and operations support let research teams focus on models while FluidStack runs the physical and orchestration layers.
Rent cloud GPUs by the second from a global marketplace
Rent from a global pool of 20,000+ GPUs spanning more than 60 GPU types, from RTX 3060-class cards to GB200s, across 40+ data centers.
Choose on-demand for guaranteed uptime, interruptible at 50%+ cheaper, or reserved terms at up to 50% off with guaranteed capacity.
Pay only for the compute you use with per-second billing and no minimum hours, so experiments and short jobs stay affordable.
Provision and optimize instances entirely through code using the CLI, Python SDK, or REST API, which also makes the platform agent-ready.
