System Requirements

Hardware Requirements

GPU (REQUIRED)

• CUDA-capable NVIDIA GPU with a current CUDA-compatible driver (CUDA 12.1+)
• Minimum: 8 GB VRAM. SDXL, the default model, requires 12 GB VRAM.
• Recommended: 16 GB VRAM
• Optimal: 24 GB VRAM

GPU Compatibility Table

VRAM Usage by Processor

Note: Only ONE diffusion model is loaded in VRAM at a time. Switching processors auto-unloads the previous model.

System RAM

• Minimum: 16 GB
• Recommended: 32 GB

Storage

• Current Windows installer: about 2.9 GB; it unpacks to about 6.2 GB
• Default first-run SDXL download: about 14 GB. Other pipelines are typically about 10–20 GB; some optional precision variants are larger.
• Render output: varies by resolution and project
• Recommended: 50 GB free SSD space

CPU

• Modern multi-core (Intel i5 / AMD Ryzen 5 or better)
• CPU is not the bottleneck — GPU handles all AI processing

Software Requirements

Operating System

• Windows only: Windows 10 (64-bit, 21H2+) or Windows 11
• macOS is NOT supported (requires NVIDIA CUDA GPU)

NVIDIA Driver

• Use a current CUDA-compatible NVIDIA driver (CUDA 12.1+)
• The latest Game Ready or Studio driver is recommended
• Check your driver: run nvidia-smi in Command Prompt

WebView2 Runtime

• Pre-installed on Windows 10/11
• If missing: download from Microsoft

Not Supported

• AMD GPUs (no CUDA support)
• Intel Arc GPUs
• Apple Silicon Macs
• Integrated graphics (Intel HD, AMD Vega)
• Cloud GPU instances (app requires local display)

Checking Your System

• In-app: Settings → GPU Information panel shows your GPU model, VRAM, and driver version
• Command line: nvidia-smi shows GPU model, VRAM, driver version
• GPU-Z (free tool) for detailed GPU specs
