| Component | Function | Complexity | |-----------|----------|-------------| | Tokenizer | Converts raw text to integers | Medium | | Embedding Layer | Maps integers to vectors | Low | | Positional Encoding | Adds order information | Low | | Transformer Blocks | Learns relationships via self-attention | High | | Output Head | Projects vectors back to tokens | Low | | Training Loop | Optimizes weights using backpropagation | Medium |

: This requires clusters of GPUs (like NVIDIA H100s) working in parallel. Loss Function

So, download that PDF. Open your terminal. Create transformer.py . Type import torch . And begin building the future, one tensor at a time.
