Google Cloud lets Kubernetes join TPU capacity into larger slices or split it into smaller ones at scheduling time, and Google says startup is up to five times faster.

Concept illustration of two monitors on stands, one above the other, each screen headed by a multicolored cloud icon and the lettering GOOGLE CLOUD, with a white card to the right of each monitor showing the same icon, GOOGLE CLOUD and a large TPU. On the upper screen three gray cubes marked TPU each sit inside their own black-outlined frame of a different size above a long dark bar labeled STARTUP TIME, while on the lower screen four TPU cubes stand side by side on a red rectangle at the left and two separate TPU cubes stand to its right, the first with a crack at its top edge, above a much shorter dark bar labeled STARTUP TIME. Printed on the image: Up to 5x faster startup, Google says.

Platform teams on reserved TPUs no longer need a separate node pool for each topology, though the startup and recovery multiples come without test settings and only reserved capacity is supported. The comparison is with building a fixed node pool for each TPU slice. The new feature divides all TPU capacity into cubes of 16 virtual machines each. At scheduling time it uses optical circuit switches, which switch connections with optical signals, to join cubes into large slices or split them into small ones, so no machines have to be set aside in advance for each shape. Google says job recovery is about 4.5 times faster, and a failure replaces only the broken cube, in about 1 to 2 minutes (Google Cloud, 2026-11-09). On-demand capacity and discounted Spot capacity can't use the feature. How we checked →
