Your PDF will dedicate an entire chapter to tiktoken (the tokenizer used by OpenAI) or sentencepiece (used by Google).

Training recipes

For massive model layers that cannot fit on one device even after sharding gradients, Tensor Parallelism (e.g., Megatron-LM) splits individual weight matrices across multiple GPUs. Intra-layer computations require high-bandwidth communication interfaces like NVLink. Mixed-Precision Training build a large language model %28from scratch%29 pdf

Attention allows tokens to dynamically weight and focus on relevant parts of the sequence. Your PDF will dedicate an entire chapter to

Using algorithms like Byte-Pair Encoding (BPE) or SentencePiece to create a vocabulary. Tensor Parallelism (e.g.
