| Memory upgrade | soldered (non-expandable) · up to 4.0 GB per the maker |
| Notes | ARM 4-core Cortex-A55 2.0GHz processor. ARM64 Cortex-A55 with 4 GB soldered RAM and no upgrade path. Docker (Container Station) is available, but QNAP's own Ollama how-to asks for 8 GB RAM for 3B models, so only 1B-class models are realistic and this is outside the maker's guidance. |

Running AI on the QNAP TS-433
It can, with limits: expect small models only, at modest speed. Models run on its CPU cores, and this configuration leaves about 2.0 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) |
| Ollama / Open WebUI or any other LLM server image | In a container (Docker) |
AI features from QNAP
| Feature | What it does | Where the AI runs |
|---|---|---|
| Qsirch RAG Search (cloud LLM mode) | Natural-language search and Q&A over NAS files; retrieval runs on the NAS but the LLM is a cloud API (Gemini, OpenAI, Azure OpenAI or OpenAI-compatible). | Cloud service or another computer |
