Chat Model

Domain: LLM Concepts

🎯 Motivation

A model fine-tuned specifically for conversation (multi-turn chat) rather than single text completion. Most modern LLMs are chat models.

πŸ“‹ Concrete Example

Base model: completes text (β€˜The capital of France is’ -> β€˜Paris, which is known for…’). Chat model: responds to messages (User: β€˜What is the capital of France?’ -> Paris).

πŸ”— Analogy

A debate club member vs a public speaker - the public speaker gives monologues (base model). The debater responds to opponents in a back-and-forth (chat model). Chat models are trained for dialogue.
