Get started coding with Corti Models - Corti API Documentation

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. Configs reference CORTI_BEARER rather than embedding secrets, so nothing sensitive lands in version control.

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)

Get your credentials

Grab your credentials from the Corti Console’s Developer Quickstart — a one-click Copy all as .env variables action copies a block containing CORTI_TENANT_NAME, CORTI_CLIENT_ID, CORTI_CLIENT_SECRET, and CORTI_ENVIRONMENT — everything the CLI needs.

Open the Developer Quickstart in the Corti Console

Install a coding agent

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

OpenCode
OpenCode Desktop

Run the setup wizard

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

npx @corti/cli init models

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

The wizard will:

Ask you to paste the .env block you copied from the Corti Console.
Probe Corti’s /models endpoint and let you pick a default model.
Detect installed agents and pre-select them (toggle with Space).
Let you choose scope: Global (~/.config), Project (current directory), or both.
Ask you to confirm before writing anything.

Press Enter to accept the defaults at each step.

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

Load the .env so CORTI_BEARER is available in your shell.

macOS / Linux
Windows (PowerShell)
Windows (cmd)

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

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"
