Large Language Model (LLM)
A Large Language Model (LLM) is a deep learning algorithm trained on massive text datasets to recognize patterns, understand context, and generate human-like text. Examples include GPT-4 (OpenAI), Gemini (Google), and Claude (Anthropic). LLMs process text in "tokens" and use attention mechanisms to understand relationships between words across long contexts.
Why LLMs Are the New Gatekeepers of Information
LLMs are fundamentally changing how people discover information. Instead of searching Google for lists of websites, users ask ChatGPT or Gemini direct questions and receive synthesized answers. This shift means LLMs are becoming the primary interface between consumers and knowledge. Understanding how they process "tokens" (text chunks) and "context windows" (memory limits) is essential for modern marketing. If your content isn't structured for LLM consumption—with clear schemas, authoritative sourcing, and fact-dense formatting—you become invisible in this new discovery paradigm. LLMs don't "read" like humans; they parse structured data and probability patterns.
