# ML-Assisted Labeling

## Overview

**ML-assisted labeling** helps automate data labeling for NLP projects. It supports open-source models, large language models (LLMs), and custom models for both span-based and row-based labeling tasks.

The extension generates labels automatically, helping reduce manual effort and allowing users to focus on reviewing results.
