# Batch: same model, later, cheaper · Undominated.ai

> 60 standard models publish a batch twin. 55 of those twins charge exactly half the standard input rate.

# Batch

Batch is the same model with later delivery. It is not a quality upgrade and is never ranked against a different model.

As of 28 серп. 2026 р., 60 standard models publish a batch twin. 55 of those twins charge exactly half the standard input rate. The median published batch input is 50% of standard. 3 twins are dearer on input.

Rates are headline input and output $/M from the catalogue, not a workload blend. Latency is not measured here. A missing twin is a missing twin.
