GESIS OpenCode Desktop Installer

This installer sets up OpenCode Desktop for the GESIS AI Server on Windows.

Download

Download the current release:

GESIS-OpenCode-Installer.exe

Then open the downloaded file.

Windows may show a warning because the installer is not code-signed. If you downloaded it from this GESIS GitLab project, choose More info and then Run anyway.

Get Your API Key

Open GESIS Open WebUI:

https://ai-openwebui.gesis.org

Sign in and click your profile icon in the top-right corner.

Choose Settings.

Open Account, find API keys, and click Show. Copy your API key.

Do not share your API key with anyone.

Install

1. Open GESIS-OpenCode-Installer.exe.
2. Paste your API key.
3. Click Check API key.
4. Select the models you want to use in OpenCode. All available models are selected by default.

When the installation is finished, start or restart OpenCode Desktop.

Problems

If your API key is rejected, copy it again from Open WebUI and retry.

If no models are shown, your account may not have model access yet. Contact the GESIS AI Server / Open WebUI administrators.

If OpenCode still shows old models, close and restart OpenCode Desktop.
