Large Language Model (LLM)
AI systems trained on massive text data that can understand and generate human language.
In Plain English
A Large Language Model is an AI trained on enormous amounts of text (often trillions of words) that can understand, summarize, translate, and generate human language. LLMs power tools like ChatGPT (built on OpenAI's GPT-5 series), Claude (by Anthropic), and Gemini (by Google). They predict the most likely next words based on patterns learned during training, which allows them to write essays, answer questions, and have conversations.
💡Real-World Example
When you ask ChatGPT to write an email for you, it's using its understanding of language patterns to generate appropriate text.
