The number of training examples the model processes before the optimizer takes a step. Larger batches give a smoother gradient estimate and use accelerator memory more efficiently; smaller batches add noise that can help generalization. Production training jobs use batch sizes from 1 to several thousand depending on the hardware and objective.
Batch size determines hardware cost per training run. AI infrastructure roles need fluency in how it interacts with gradient accumulation, learning rate, and memory.
