The transformer architecture is the neural network design underlying modern LLMs — including GPT, Claude, and Gemini. It uses self-attention mechanisms to process and generate text, enabling models to capture long-range relationships between words and concepts across entire documents.
Transformer architecture explains why semantic coherence matters more than keyword frequency in AI search. Transformers process meaning through attention across the full context — a document that clearly develops a coherent argument about a topic will be represented more accurately than a document that mentions the right keywords without building a clear semantic structure. For brands, this means writing that develops ideas clearly and consistently produces better AI representation than keyword-stuffed content.
