# LLMs

> Use large language models (LLMs) for chat, prompt writing, and vision inside ComfyUI workflows through Partner Nodes

## Overview

Use large language models (LLMs) from Anthropic, Google, OpenAI, and OpenRouter inside your workflows. These nodes take text and images as input and return text, which makes them useful for prompt writing, image captioning, and conversation alongside your generation nodes.

Browse the models in this section to see what each partner offers, or check [Pricing](/tutorials/partner-nodes/pricing) for per-model rates.
