Large Language Model (LLM)
A neural network trained on massive text corpora to understand and generate human language.
A Large Language Model (LLM) is a neural network — typically based on the transformer architecture — trained on hundreds of billions to trillions of tokens of text data to predict the next token in a sequence. This simple objective produces sophisticated language understanding and generation. Notable LLM families include OpenAI's GPT series, Anthropic's Claude, Google's Gemini, Meta's Llama, and Mistral's models. Modern LLMs power chatbots, content generation, code assistants, agents, and retrieval-augmented generation (RAG) systems. Empire325 builds production LLM applications including custom agents, RAG systems with vector databases, fine-tuned models for domain-specific tasks, and evaluation frameworks.
