OverWatch runs its detector, vision, and language models locally in your browser via WebGPU (with WebGL/WASM fallback). On first visit these models download from the Hugging Face Hub — this can take a moment on a cold cache. Once cached, subsequent loads are instant. Telemetry and connectors work independently while models load.
