Tensor split

Also known as: layer split ยท multi-GPU split

Local

Tensor split (layer/weight split) divides a model’s layers across multiple GPUs โ€” or between GPU and CPU โ€” so a model that’s too big for one device can still run.

  • Split 70B across two 24 GB cards.
  • Or offload a fraction of layers to CPU.
  • The per-token speed reflects the slowest device in the chain.

The "make it fit" tool: when one GPU isn't enough, tensor split is how you stretch a big model across what you have โ€” at the cost of the slowest link.
