What is LLM (Large Language Model)?

An LLM (Large Language Model) is an Artificial Intelligence system trained on terabytes of text — books, code, articles, conversations — to predict the next word in a sequence with extremely high statistical precision. It's that prediction capability, at scale, that produces what looks like "understanding" and "reasoning."

How an LLM differs from traditional software

Traditional software follows explicit rules written by a programmer (IF this THEN that). An LLM doesn't follow rules — it generalizes patterns learned during training. That makes it flexible enough to answer questions it has never seen before, but also prone to hallucination: generating a plausible, grammatically correct answer that is factually wrong.

Why it matters for your B2B business

Running an LLM on top of your company's disorganized data — with no structure, no Ground Truth — is a recipe for hallucination in production. That's why serious corporate AI architectures combine the LLM with techniques like RAG (Retrieval-Augmented Generation), which constrain the model's answer to your real knowledge base instead of letting it "make things up" from generic training.
