Model Sharding

Definitions

1. Model Sharding is a systems strategy for splitting model computation or parameters across devices. It is commonly used for training and serving workloads that exceed a single accelerator, where teams need predictable behavior under real workloads rather than toy examples. Practitioners pay attention to communication overhead, memory balance, and fault tolerance, because those factors usually determine whether the approach improves quality, latency, reliability, or operating cost in production.

   In plain English: Model Sharding is an AI concept teams use to train models, guide predictions, or make model behavior more reliable and easier to control in practice.

   Example: "We evaluated Model Sharding in the new model pipeline because the baseline was plateauing; once it was wired into training and evaluation, quality improved enough to justify rolling it into the next release."
