Implementing vanilla attention is O(n²). FlashAttention reduces memory reads/writes. The PDF will explain the tiling algorithm but likely provide a kernel in Triton.
But can one person actually build an LLM from scratch? The answer is —provided you lower your expectations regarding size (think millions of parameters, not trillions) and focus on the architecture. build a large language model from scratch pdf
