## Overview

**Nous Research** developed and released the [Hermes 3](https://huggingface.co/NousResearch/Hermes-3-Llama-3.2-3B), a state-of-the-art instruction-tuned language model built on Llama-3.2-3B. This 3-billion parameter model is a fine-tuned version of Llama-3.2 and represents a leap forward in reasoning, multi-turn conversation, and structured outputs. It incorporates advanced role-playing capabilities, reliable function calling, and improved coherence over long contexts, making it a versatile assistant for various applications.

Hermes 3 was trained with high-quality data, leveraging fine-tuning techniques on H100 GPUs via LambdaLabs GPU Cloud. The model excels in both general-purpose and specialized tasks, including code generation, reasoning, and advanced conversational abilities. With support for ChatML prompt formatting, Hermes 3 ensures compatibility with OpenAI endpoints and facilitates structured, steerable interactions for end-users.
