| Notes | Intel Xeon D-2733NT. CPU only as sold: Xeon D with AVX-512 and DL Boost (VNNI), 8 ECC slots up to 1 TB, so large models fit in memory but run at CPU speeds. PCIe x8 slots exist, but the maker lists them for NICs and SAS HBAs and publishes no GPU support. No benchmark found. |

Running AI on the TerraMaster U12-725 Plus
Yes, it runs AI models on the NAS itself. Models run on its CPU cores, and this configuration leaves about 471 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. More memory is the upgrade that matters most: see the configurations.
Apps you can install to run models
| App | How it installs |
|---|---|
| Ollama | In a container (Docker) |
| Open WebUI | In a container (Docker) |
AI features from TerraMaster
| Feature | What it does | Where the AI runs |
|---|---|---|
| Terra Photos (TerraMaster Photos) | Photo library with face and scene recognition; the maker says the AI processing uses a local model on the NAS. This is an image classifier, not a chat model. | On the NAS |
| OpenClaw AI agent (built into TOS 7) | Natural-language control of NAS functions. The maker setup guide has the user pick a model provider (such as OpenAI) and paste an API key, so the language model runs remotely by default, not on the NAS. | Cloud service or another computer |
