Which model does Depth use?

Depth Anything V2 Small by DepthAnything (HKU / TikTok), under Apache-2.0. runonweb loads the onnx-community/depth-anything-v2-small weights and runs fp16 on WebGPU · q8 on WASM.

How big is the Depth download?

~50 MB / ~27 MB, fetched once on first use. The browser caches the weights, so later loads skip the network and keep working offline.

What does Depth cost?

Nothing. runonweb is free and MIT-licensed, with no device limits, tokens or sign-in. The weights keep their own license: Apache-2.0.
