# Overview

> The ZylonGPT API lets you generate responses, ingest knowledge, create embeddings, and call tools in one flow.

ZylonGPT is the model-facing API. Most apps follow a simple loop: send messages, attach or reference artifacts, generate embeddings for search, and let the assistant call tools when it needs structured data or retrieval.
