Training models with billions of parameters cannot fit into a single GPU's Memory (VRAM). Distributed strategies partition the training workload across arrays of accelerators. Parallelism Strategy Primary Splitting Mechanism Best Used For Splits batches across GPUs; synchronizes gradients. Models small enough to fit on one GPU. Tensor Parallelism (TP) Splits matrix multiplications intra-layer across GPUs. Massive hidden dimensions ( dmodeld sub m o d e l end-sub Pipeline Parallelism (PP) Splits sequential layers inter-node sequentially. Deep architectures across separate servers. FSDP / ZeRO Shards weights, gradients, and optimizer states. Highly scalable, modern default alternative. Memory Management Tricks Allowing tokens to interact with other tokens in

Removing low-quality spam, toxic content, and machine-generated gibberish using fast text classifiers (e.g., FastText). Massive hidden dimensions ( dmodeld sub m o
