Splits individual weight matrices across multiple GPUs (e.g., Megatron-LM style). Crucial for layers that exceed single-GPU limits. build large language model from scratch pdf
NVIDIA GPUs (A100/H100 for large, T4/V100 for small), or cloud solutions like Google Colab or Lightning Studio.
Have you successfully built a nanoGPT from a PDF? Share your training loss curves (and debugging horror stories) in the comments.
Modern LLMs are built on the , specifically the decoder-only variant (like GPT models). Before writing code, you must define the structural hyperparameters that dictate your model's capacity and computational cost.

Provide the full code for MultiHeadAttention and explain why we use causal masking (preventing the model from seeing future tokens).

Use BF16 (Bfloat16) over FP16. BF16 shares the same dynamic range as FP32, preventing underflow/overflow issues without requiring complex loss scaling.
Modern LLMs rely on the Transformer architecture. When building from scratch, you must choose between encoder-only (e.g., BERT), decoder-only (e.g., GPT), or encoder-decoder (e.g., T5) setups. For generative AI, the decoder-only model is the industry standard.
