First Setup

After signing in, check account, model and subscription settings. The server database configures the model catalog dynamically; use the models actually available to your account in the IDE. Different features may use different model configurations.

Setup Checklist

1. Confirm your account and subscription usage in Settings.
2. Select an available model. If the list is empty, check connectivity, sign-in state and kernel readiness.
3. Install and configure the LSP for your project language yourself. A missing-language-service banner indicates unavailable language support; basic editing remains usable, but diagnostics and navigation require a ready server.
4. Before debugging Python, Node, Java or Go, install debugpy, js-debug, jdt-java-debug or Delve (dlv) respectively, plus the required runtimes.
5. For BYOK, configure the endpoint, model name and key supplied by your provider, and check the channel selected by the feature you use.

Kernel Connection

The kernel defaults to loopback and port 3721. The port may change when occupied; use the IDE's actual connection address rather than assuming a fixed port. LAN pairing can enable an additional LAN listener. Protect pairing credentials and never expose the kernel directly to the public internet.

Global data uses LINGXIZHI_HOME when set, otherwise the data directory beside the executable, not ~/.lxz. Project-level .lxz data has a separate purpose.

Next Steps
