Depth Anything V2 Small (fabric)

An Apple Core AI conversion of depth-anything/Depth-Anything-V2-Small-hf — a monocular depth estimator that maps a single RGB image to a per-pixel (inverse-)depth map. Produced by coreai-fabric and indexed by coreai-catalog.

Dense prediction, fully on-device. This is a single-forward dense predictor — RGB image (1×3×518×518) in, per-pixel depth (1×518×518) out, no loop. The host owns only image preprocessing (resize to a multiple of 14, ImageNet normalize) and any depth colormap for display.

Model facts

Use it — this needs host code you supply

The bundle is a single static-size graph: pixel_values (1×3×518×518) in → predicted_depth (1×518×518) out. You supply the resize-to-multiple-of-14 + ImageNet normalization and any visualization/colormap in your host code (Swift or Python).

pip install coreai-catalog && coreai-catalog install depth-anything-v2-small

Requirements

• Deployment: macOS 27.0+ / iOS 27.0+, Xcode 27+. The asset serializes with minimum_os v27, so the on-device Swift runtime requires macOS/iOS 27+. A Mac on macOS 26 can convert and inspect it but not run it on-device.
• Apple Silicon.

Verification (output parity)

• Gate A (structure): passed — the bundle's layout + metadata were validated; the graph loads.
• Gate B — graph_output_cosine: 1.000000 min output cosine (median 1.000000) vs the fp32 torch depth model over 8 seeded pixel_values, measured on apple_silicon. Certifies the export computes the SAME output as the source — a conversion-fidelity metric, not task accuracy.
• This certifies the export is numerically faithful to the source model — it does NOT certify absolute depth accuracy on your images. Reproduce with coreai-fabric verify.
