How LLMs Actually Work
LLMs operate by converting text into subword tokens and mapping them to numerical vectors called embeddings that represent semantic meaning. These models use positional encoding to track the order of words and use attention mechanisms to allow tokens to weigh the importance of other information in a sequence. Within the transformer stack, feed-forward networks process tokens individually while residual connections and normalization layers maintain mathematical stability across many layers.
