| Notes | Intel Celeron J3455. x86-64 with Container Manager, but RAM tops out at 8 GB officially and the Intel Celeron J3455 (4C/4T) is a low-power CPU (Celeron J-series lack AVX), so only 1-4B-parameter quantized models are realistic, slowly. |

Running AI on the Synology DS1019+
It can, with limits: expect small models only, at modest speed. Models run on its CPU cores, and this configuration leaves about 5.2 GB for them after the NAS system and its storage services. The grades below assume the NAS isn’t busy with backups or media work at the same time.
Apps you can install to run models
| App | How it installs |
|---|---|
| Ollama + Open WebUI | In a container (Docker) |
| Any Linux guest running llama.cpp / Ollama | In a virtual machine |
