Install
- Download
Nebula_2.0.0_x64-setup.exe. - Verify its SHA-256 checksum against
Nebula_2.0.0_x64-setup.exe.sha256. - Install and launch Nebula.
- In LM Studio, load a compatible instruction or coding GGUF and start the local server.
- Select the discovered model in Nebula. The default endpoint is
http://localhost:1234/v1/chat/completions.
Models are not bundled. Nebula remains usable while LM Studio is offline and shows a recoverable connection state.
Safety
Nebula starts in Safe mode. Full Access lasts only for the current session, requires typed confirmation, never elevates to administrator, and does not bypass catastrophic-action blocks.
Rollback
If 2.0 does not work on a system, uninstall it and reinstall the previous Nebula package. Conversations and settings are backed up during the durable-storage migration; do not delete %LOCALAPPDATA%\Nebula when preserving local state.
