LLM Large Language Model
An AI model trained on huge amounts of text that can generate, translate or reason with text.
Behind Claude, ChatGPT, Gemini, Llama. Trained on trillions of words from the internet, books and code. Size is measured in parameters — 7B (smaller, fast), 70B (mid-range), 400B+ (top-tier models).
What they aren't: an oracle. They can hallucinate, they can be biased, they know nothing about events after their training cutoff. Use them as a very fast, very broad junior — review the output.
