# OpenCode-Nemotron-7B Overview

## Description 

OpenCode-Nemotron-7B is a large language model (LLM) which is a derivative of [Qwen2.5-7B-Instruct](https://huggingface.co/Qwen/Qwen2.5-7B-Instruct) (AKA the *reference model*). 
It is a reasoning model that is post trained for reasoning while code generation. The model supports a context length of 32K tokens.

This model is ready for commercial use.
