You pay for the run,
not the cluster.

Compute is billed per GPU-hour at the rate the scheduler actually won it for. No reserved capacity you are not using, no minimum, no seat licence.

How the billing works

Why the rate moves

The scheduler bids for interruptible capacity across regions. When the market is quiet you pay less, and we pass that through rather than pocketing the spread. The prices above are ceilings, not averages.

What a real invoice looks like

An 8B LoRA tune on 240M tokens finishes in about four hours on 24 GPUs, so roughly 95 GPU-hours: about $180 on Flow, $130 on Reserved. Ingestion, tokenisation and every evaluation you run afterwards are free.

Leaving

Export the weights and go. There is no egress fee, no licence that lapses, and no request form: penstock export works on the last day of your account exactly as it did on the first.
