What is Large Language Models (LLMs)?
Overview
A large language model (LLM) is an AI model trained on large text datasets to understand and generate language, code, and structured responses. LLMs matter because they provide the foundation for modern assistants, coding tools, search products, and agents, while their reliability still depends on context, tools, evaluation, and deployment choices.
Why it matters
LLMs turn general language capability into a reusable platform for AI products, but model quality alone does not guarantee accurate or dependable results.
Where it appears in AI research
- AI assistant and coding tool launches
- Model training and evaluation research
- Agent, RAG, and tool-use systems
- Enterprise AI deployment decisions
