# Opencode

[**Opencode**](https://opencode.ai/) is a powerful, open-source AI coding agent built specifically for the terminal, featuring a native, responsive, and themeable terminal user interface. **Opencode** offers developers terminal-based coding assistance, debugging, file management, and command execution — all within the CLI.<br>

This guide will walk you through the setup process and show you how to combine **Opencode** with **Cortecs** for enhanced productivity.

{% hint style="info" %}
*Before you begin: Make sure you have generated your Cortecs API key. If not, check out our* [*QuickStart*](https://docs.cortecs.ai/quickstart) *guide.*
{% endhint %}

## 1. Install Opencode

Run the following command in your terminal to install Opencode:

```apache

Choose the model you want to use and press Enter ✅.

> 💡 **Tip:** If you’re looking for a specific model, you can either:
>
> * Join the [Discord](https://discord.com/invite/bPFEFcWBhp) community 💬 and request it, or
> * Add it directly to the [Models.dev](https://github.com/sst/models.dev/tree/dev/providers/cortecs/models) open-source database in the Cortecs provider folder.

**You’re all set!** 🎉

You can now start a discussion with your AI agent!
