A Jupyter Notebook that implements the Llama 3 language model from scratch, building each tensor and matrix multiplication step by step while loading Meta's official model weights directly. It serves as an educational walkthrough of transformer internals including tokenization, attention, and feed-forward layers.

Use cases

• understand how llama3 works internally
• learn transformer architecture from scratch
• implement attention and matrix multiplications manually
• study how model weights are loaded from checkpoint files
• teach large language model fundamentals
• follow along a hands-on LLM implementation tutorial

When to choose

• you want to deeply understand LLM internals rather than just call an API
• you are learning how transformers and attention work at the tensor level
• you want a readable, step-by-step educational notebook with real Meta weights

When to avoid

• you need a production-ready inference engine with optimized performance
• you want a maintained library with releases and support
• you need training or fine-tuning capabilities rather than inference walkthrough
