Large language models
Also used: LLM, LLMs, Large language model
A large language model, or LLM, is an AI model trained on large amounts of text to predict and generate language one piece at a time.
Why it matters to educators
Many education-facing AI tools are powered by LLMs. Knowing the underlying model is a language predictor helps educators understand why responses can be fluent and useful while still being incomplete, biased, or factually wrong.
The foundation
An LLM identifies patterns in language and uses those patterns to continue from the prompt and context it receives. It can summarize, classify, explain, draft, translate, and reorganize language without storing a verified answer for every possible question.
The chatbot or application is the interface; the LLM is one part of the system behind it. Different applications may use the same model but add different instructions, tools, safety settings, data access, and privacy terms.
What this can look like in education
Transform curriculum language
An educator supplies a standard and asks an LLM to draft student-friendly learning targets, then checks that the meaning and rigor were preserved.
Organize a policy excerpt
An administrator provides the relevant policy text and asks for a categorized summary, using the original document—not the model's memory—as the authority.
