Developers build LLMs from scratch to demystify Transformers

By PulseAugur Editorial · [2 sources] ·

Two developers share their experiences building small Large Language Models from scratch to understand the underlying components. They detail the process of converting text into numerical tokens, the role of embeddings, and the mechanics of the Transformer architecture, including attention mechanisms, Query/Key/Value interactions, and feed-forward networks. The posts also touch upon normalization techniques like RMSNorm and positional encoding methods such as RoPE, highlighting how these elements contribute to an LLM's ability to process and predict text.
