What is LLM (Large Language Model)?

Turkish: LLM

An LLM is a model trained on large text datasets that can understand and generate natural language, forming the basis of tools like ChatGPT.

What is an LLM?

An LLM (Large Language Model) is a model that breaks text into pieces called tokens and learns patterns between those tokens. Given a prompt, it predicts likely next tokens, which makes it useful for question answering, summarization, classification, and text generation.

Most modern LLMs are based on the transformer architecture. Their behavior is shaped by training data, context window size, system instructions, generation settings such as temperature, and any additional information supplied to the model. Because output is probabilistic, the same question may not always produce the same answer, and confident-sounding responses can still be wrong.

Business Use and Limits

  • Customer support drafts, knowledge-base search, and email summaries
  • Document classification, meeting-note extraction, and content drafts
  • Code assistance, test-case suggestions, and technical documentation explanation
  • RAG workflows that answer from internal company documents

Successful LLM projects are not only about writing good prompts. Privacy, evaluation sets, hallucination control, authorization, cost, and human review need explicit design. The topic connects to AI, NLP, RAG, and prompt engineering.
