Last updated

Full definition
A Large Language Model (LLM) is a transformer-based neural network trained on billions to trillions of text tokens that can understand, summarize, generate and reason about text. Major LLMs in 2026 include OpenAI's GPT series (powering ChatGPT), Anthropic's Claude, Google's Gemini, Meta's Llama, and the LLMs powering Perplexity and other answer engines. LLMs are reshaping search: Perplexity, Google AI Overviews and ChatGPT search increasingly replace traditional Google results, and creators must optimize for citation by LLMs (AEO/GEO) in addition to traditional ranking factors.
Examples
- ·Claude Opus answering 'best AI video tool for creators' by citing reviews from Content Creator Tools and other methodology-driven sources.
- ·Perplexity providing a researched answer to a product comparison query with linked citations.
