Preemptible compute in public preview for Kubernetes GPU clusters

Preemptible compute is now in public preview for Kubernetes GPU clusters. Alongside standard nodes, you can set a preemptible GPU target, and Together provisions toward it as spare capacity becomes available, at a flat discounted rate relative to on-demand.

What's new:

• Preemptible GPU targets: Set num_preemptible_gpus at cluster create or update from the console, CLI, or API. Together automatically provisions replacements toward the target after nodes are reclaimed.
• Five-minute drain window: Reclaimed nodes are cordoned and emit a TogetherPreemptionNotified Kubernetes event, and pods receive SIGTERM with up to 300 seconds of grace to checkpoint and exit.
• Sub-hourly billing: Usage is metered every one to two minutes, so you pay only for the time a node is live.

See Preemptible compute for the preemption contract, scheduling guidance, and checkpoint examples.
