HardwareDiffers

Standard Docker deployment: 4-core CPU and 8 GB RAM to start, excluding Ollama model weights; x86 CPUs need x86-64-v2; disk scales with knowledge base

GPU optional (CUDA image falls back to CPU); RAM not documented; depends on model

App is lightweight; local model serving depends on model, GPU and VRAM (NVIDIA and AMD Docker overlays; CPU-only works)

Official installation docs describe Docker/Kubernetes servers and a source-built macOS desktop app. Windows/Linux/macOS desktop build targets exist, but the docs warn that release installers are not published

macOS, Linux (x86_64, ARM64) and Windows (Docker via WSL)

Docker on any host; native Linux, macOS (incl. Apple Silicon) and Windows
