Removing memory bottlenecks without complex tensor splitting. 4. The Pre-training Phase

Raw text must be broken into smaller units (tokens). Modern models use sub-word tokenization to handle large vocabularies efficiently. build a large language model from scratch pdf

Rent or orchestrate target cloud GPUs (A100/H100 instances) and convert training loops to use bfloat16 precision. Removing memory bottlenecks without complex tensor splitting

: Divides layers sequentially across GPUs. GPU 0 handles layers 1–6, GPU 1 handles 7–12, and so forth. 5. Post-Training and Alignment GPU 1 handles 7–12
