## About

## What it does
Chat Completions lets you send a list of messages and get a model-generated assistant reply back in the same OpenAI-style format. It is built for conversational applications that need a structured response shape and familiar parameters like `model`, `temperature`, `top_p`, `max_tokens`, and `stream`.

Send one or more messages with a `role` and `content`, and the service returns a completion object with an `id`, `model`, `created` timestamp, `usage` counts, and a `choices` array. Each choice includes the generated message with its role and content, plus a `finish_reason` so you can handle truncation or completion states in your client logic.

Use Chat Completions when you need to add AI chat to support workflows, internal assistants, content drafting, or task-oriented agents. The response format is predictable, which makes it easier to log, store, and render in applications that already follow chat-style request and response patterns.
