# YuE2 music engine
`engine: "yue2"` is standalone [YuE2](https://github.com/multimodal-art-projection/YuE) (`m-a-p/YuE2-3B` + `m-a-p/YuE2-Vae`). It never submits a Comfy graph. `engine: "yue"` remains YuEGP in code. ACE / ACE 1.5 keep their Comfy workflows.
`engine: "yue2"` is the only music engine in the app. Standalone [YuE2](https://github.com/multimodal-art-projection/YuE) (`m-a-p/YuE2-3B` + `m-a-p/YuE2-Vae`). It never submits a Comfy graph. ACE / YuEGP are removed from the picker and generate API; leave ACE Comfy checkpoints on disk.
## Desktop agent at boot (one click)
Wrong agent on 8199 → `/yue2/status` returns `{"ok":false,"error":"not found"}` while Comfy images still work.
Fix once from this clone:
```powershell
.\scripts\install-comfy-host-agent-launchers.ps1
```
That rewrites Desktop, Start Menu, and **Windows Startup** shortcuts to this clone, and retargets the `AIGen Comfy Host Agent` scheduled task when it exists. Each launch **kills** any old `comfy-host-agent` / listener on 8199, then starts `scripts/comfy-host-agent.mjs` (imports `yue2-host.mjs`).
After install: double-click Desktop **Start Comfy Host Agent**, or reboot. Confirm:
```text
GET http://127.0.0.1:8199/yue2/status → 200 { configured, busy, backend: "yue2" }
```
Do not guess which `node.exe` to kill — the launcher replaces it.
