← All terms · AI providers and models

Also called Conversational model

An AI model optimized for rapid, natural back-and-forth dialogue and immediate task execution, without an extended internal reasoning phase.

What it is

Chat models (like standard GPT-4o or Claude 3.5 Sonnet) are fine-tuned to act as responsive conversational agents. They excel at immediately predicting the next token, making them fast and highly effective for general drafting, basic coding, and interactive tool orchestration where low latency is required.

When you would use it

You use a chat model when you need fast, fluid interactions, general text generation, or responsive API tool-calling where a long "thinking" delay is unacceptable.

Common operations

  • Powering customer service chatbots.
  • Driving real-time IDE autocomplete and fast inline code generation.
