Get started coding with Corti Models

Connect your terminal AI coding agent to Corti’s EU-hosted language models. Install a supported agent, run the Corti CLI, and start coding — every prompt is processed on Corti’s EU infrastructure.

The Corti CLI writes a corti provider entry into each selected agent’s config and manages a .env block with your credentials. Each config references CORTI_BEARER rather than embedding the secret itself.

Before you start

You’ll need:

A terminal on macOS, Linux, or Windows
Node.js 18+ installed (required to run the Corti CLI via npx)
A Corti Console account (free to create)

Install a coding agent

The Corti CLI supports the following agents. Install one (or more) using your preferred method.

Run the setup wizard

Run the interactive setup to authenticate and configure the Corti provider for your installed agents:

npx @corti/cli models init

npx requires Node.js 18+. Download it from nodejs.org or install via a version manager like fnm or nvm.

The wizard opens by asking how you want to sign in:

◆ How do you want to sign in?
│  ▸ ● Log in with a browser
│    ○ Paste an API key
│    ○ Enter client credentials
└ ↑↓ move · enter select

Press Enter to accept the default, Log in with a browser. The CLI shows a one-time code and opens the Corti Console. Approve the sign-in there, and the terminal continues on its own.If the browser can’t open automatically, for example over SSH, the CLI prints a URL for you to open instead.

Paste an API key instead

In the Console, open Corti Models and generate your personal API key.
In the CLI, choose Paste an API key and paste it.

The value is masked on entry and stored as CORTI_BEARER.Client credentials still work as well, mainly for headless and CI runs.

Once you’re signed in, the wizard:

Verifies the connection and probes /models so you can pick a default model.
Detects installed agents and pre-selects them (toggle with Space).
Lets you choose scope: Global (~/.config), Project (current directory), or both.
Shows a plan and asks you to confirm before writing anything.

Press Enter to accept the defaults at each step.

Where the CLI writes your config

The CLI writes a corti provider entry into each selected agent’s config file, plus a managed .env block with your credentials:

ForgeCode — ~/.forge/.forge.toml
OpenCode — ~/.config/opencode/opencode.json (or .jsonc)
Crush — ~/.config/crush/crush.json
Pi — ~/.pi/agent/models.json

Load your credentials

If you let the CLI update your shell startup file, open a new terminal and skip ahead.Otherwise, load the .env manually. Global scope writes it to ~/.env, project scope to .env where you ran the CLI.

macOS / Linux
Windows

set -a; . ~/.env; set +a

for l in (cat ~/.env); string match -q '*=*' -- $l; and set -gx (string split -m 1 = -- $l); end

Get-Content "$HOME\.env" | ForEach-Object {
    $line = $_.Trim()
    if ($line -and -not $line.StartsWith('#')) {
        $name, $value = $line -split '=', 2
        Set-Item -Path "Env:$($name.Trim())" -Value $value.Trim().Trim('"').Trim("'")
    }
}

for /f "usebackq eol=# tokens=1* delims==" %A in ("%USERPROFILE%\.env") do @set "%A=%B"
