Bundled installers (Bundle)

The version selector above lists Bundle downloads separately for each release: Bundles include runtimes, Harness, and built-in plugins to reduce first-launch downloads. Model access and later updates may still need a network connection. Releases without Bundles do not show this download list.

Systems and installers

These are the actual release assets and system requirements: Available architectures and installer types depend on the selected release’s actual assets. Git features such as worktrees also require Git installed on your system. On macOS, you can also use Homebrew:

Verify the download source, then allow the app in System Settings → Privacy & Security. Even when macOS meets the minimum version, check WebView compatibility too.
Try .deb first. If AppImage still shows a black window, try:
