{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    nur.url = "github:nix-community/NUR";
  };

  outputs = { self, nixpkgs, nur, ... }: {
    nixosConfigurations.your-hostname = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        nur.modules.nixos.default
        nur.repos.charmbracelet.modules.crush
        {
          programs.crush = {
            enable = true;
            settings = {
              providers = {
                openai = {
                  id = "openai";
                  name = "OpenAI";
                  base_url = "https://api.openai.com/v1";
                  type = "openai";
                  api_key = "sk-fake123456789abcdef...";
                  models = [
                    {
                      id = "gpt-5.6-sol";
                      name = "GPT-5.6 Sol";
                    }
                  ];
                };
              };
              lsp = {
                go = { command = "gopls"; enabled = true; };
                nix = { command = "nil"; enabled = true; };
              };
              options = {
                context_paths = [ "/etc/nixos/configuration.nix" ];
                tui = { compact_mode = true; };
                debug = false;

}

sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://repo.charm.sh/apt/gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/charm.gpg
echo "deb [signed-by=/etc/apt/keyrings/charm.gpg] https://repo.charm.sh/apt/ * *" | sudo tee /etc/apt/sources.list.d/charm.list
sudo apt update && sudo apt install crush

echo '[charm]

baseurl=https://repo.charm.sh/yum/
enabled=1
gpgcheck=1
gpgkey=https://repo.charm.sh/yum/gpg.key' | sudo tee /etc/yum.repos.d/charm.repo
sudo yum install crush

Or, download it:

• Packages are available in Debian and RPM formats
• Binaries are available for Linux, macOS, Windows, FreeBSD, OpenBSD, and NetBSD

Or just install it with Go:

go install github.com/charmbracelet/crush@latest

On illumos (OpenIndiana, OmniOS), the command above works as-is. Only native OS notifications are unavailable there; terminal-based notifications (OSC) and the terminal bell still work. On Oracle Solaris, add -tags sqlite3_dotlk so the local database uses dot-file locking:

go install -tags sqlite3_dotlk github.com/charmbracelet/crush@latest

[!WARNING] Productivity may increase when using Crush and you may find yourself nerd sniped when first using the application. If the symptoms persist, join the [Slack][slack] or [Discord][discord] and nerd snipe the rest of us.

Getting Started

The quickest way to get started is to choose a Hyper model from model picker. Follow the steps to authenticate and you'll be good to go.

Hyper, from Charm, is the official Crush provider. It’s subscription-based and optimized for Crush. It’s privacy focused, with zero data retention (ZDR) and is designed to comply with GDPR. More on Hyper.

API Keys

You can also use Crush with many other providers such as Anthopic, OpenAI, Gemini, OpenRouter and so on. Press ctrl+l to open the model picker, choose the provider of your choice, and paste your API key.

That said, you can also set environment variables for preferred providers:

Also note that Crush can support nearly any provider, including Local Models. For more info see Custom Providers below.

By the Way

Is there a provider you’d like to see in Crush? Is there an existing model that needs an update?

Crush’s default model listing is managed in Catwalk, a community-supported, open source repository of Crush-compatible models, and you’re welcome to contribute.

Configuration

[!TIP] Crush ships with a builtin skill for configuring itself. Most of the time you can just tell what you want it to configure and it will get the job done.

Crush runs great with no configuration. That said, if you do need or want to customize Crush, you can, with a crushrc.

A crushrc is just Bash with some Crush-specific builtins. It’s a lot like a .bashrc, just for your Crush. Because Crush has a native, built-in Bash interpreter, Bash-based config works identically across all platforms, including Windows.

For example:

```bash

Add Ollama.

provider add ollama --type ollama --base-url "http://localhost:11434/v1"

Register a model on Ollama.

model add ollama/llama3.3 --name "Llama 3.3" --context-window 128000
