Installing OptimaGPT
OptimaGPT is installed using the OptimaGPT installer, available from the downloads page on our website. The installer handles the Gateway, Node, and desktop chat application and works across Windows, Linux, and macOS.
Linux headless servers: If you are installing on a Linux machine without a graphical interface, see Headless Installation instead.
Download the installer
Download the OptimaGPT installer from the downloads page at www.optimagpt.com. The correct installer for your platform and architecture will be indicated on the page.
Launch the installer
Run the downloaded installer file. The OptimaGPT installer window will open.

Click Install.
Select what to install
Choose which components to install on this machine.

| Option | What it installs |
|---|---|
| Gateway and Node | Both components on this machine |
| Gateway | The Gateway only — inference will run on a separate Node machine |
| Node | A Node only — to be connected to a Gateway running elsewhere on the network |
For a single-machine setup, choose Gateway and Node.
Install from pre-release CDN: Check this box only if directed to do so by Parker Software support. It installs the latest pre-release build rather than the current stable release.
Once you have made your selection, click Install.
Installation progress
The installer will locate the latest available version of each selected component, download it, and register it as a background service.

When prompted to confirm a version — for example, Install Node 2.0.4? — click Yes to proceed.
The installer completes the following steps for each selected component:
- Find the latest available version
- Download the package
- Unpack the files
- Register the background service
Once all steps are complete, the selected components are installed and running as background services. They will start automatically when the machine boots.
Next steps
Open a web browser and navigate to the Gateway's address:

You will be taken through the first-time setup process. See First-Time Setup.
