CLI installation

Install the Pioneer CLI when you want terminal access to training jobs, model artifacts, datasets, and the interactive Pioneer agent.

Pioneer CLI is published as @fastino-ai/pioneer-cli and runs with Bun 1.1.0 or newer.

Requirements

macOS or Linux
Bun 1.1.0 or newer
Node.js and npm
A Pioneer API key from Pioneer API keys

Install the CLI

Install Bun

curl -fsSL https://bun.sh/install | bash

Open a new terminal after the installer finishes, then confirm Bun is available:

bun --version

Install Pioneer CLI

npm install -g @fastino-ai/pioneer-cli

Verify the command

pioneer --version
pioneer --help

Authenticate

Create an API key

Create an API key in the Pioneer dashboard, then keep it ready for the login prompt.

pioneer auth login

The CLI validates the key before saving it.

Confirm your session

pioneer auth status

Interactive login stores your API key in ~/.pioneer/config.json. The CLI also supports PIONEER_API_KEY for CI or short-lived shell sessions.

Check the setup

Run a few read-only commands to confirm the CLI can reach Pioneer:

pioneer --version
pioneer auth status
pioneer model base-models
pioneer dataset list

Update

npm install -g @fastino-ai/pioneer-cli@latest
pioneer --version

Troubleshooting

pioneer: command not found

Make sure your global npm bin directory is on PATH.

npm bin -g

env: bun: No such file or directory

Install Bun and open a new terminal:

curl -fsSL https://bun.sh/install | bash
bun --version

Authentication fails

Create a new API key in the Pioneer dashboard, then run interactive login again.

pioneer auth login
pioneer auth status
