System Requirements
Hardware and software prerequisites for running Ocsidian.
Ocsidian runs alongside Unreal Engine on your local machine. The AI processing happens in the cloud, so your internet connection matters more than your GPU for generation speed — but you still need a capable machine for Unreal Engine rendering.
Minimum requirements

|---|---|---|
| OS | Windows 10 / macOS 13 / Ubuntu 22.04 | Windows 11 / macOS 14+ / Ubuntu 24.04 |
| CPU | 6-core / 3.0 GHz | 8-core+ / 3.5 GHz+ |
| RAM | 16 GB | 32 GB+ |
| GPU | 4 GB VRAM (DirectX 12) | 8 GB+ VRAM (RTX 3070 or M1 Pro equivalent) |
