Calm power for AI racks.

GPU training makes rack power swing by tens of kilowatts in under a second. You size power, UPS, and cooling for the peak, and pay for it. Kelluma measures those swings and smooths them, so you can run more GPUs on the power you already have.

The problem

Synchronous training moves thousands of GPUs from full power to near idle and back, again and again. That stresses UPS systems, trips on-site generators, wastes energy on dummy loads, and strands capacity you've already paid for.

How it works

STEP 1MeasureA clip-on sensor kit records your rack's power at high speed for a week. No software changes, nothing touching your jobs.

STEP 2SeeYou get a clear report: peak versus average, swing frequency, and how much headroom smoothing would unlock.

STEP 3SmoothA rack-level energy storage shelf absorbs the spikes on its own, independent of your training software.

Built for smaller neoclouds

Hopper and AMD fleets, 48V open racks, and sites on tight or on-site power. If you own your racks, we'd like to measure one.
