# cuPyNumeric API support Source: https://nv-legate.github.io/cupynumeric/api/comparison.html Fetched: 2026-05-22T15:45:33+00:00 Counts: 616 total · 412 implemented · 363 multi-GPU · 9 single-GPU only · 14 partial · 204 not implemented Legend - `✓✓` implemented and works on multi-GPU (the best path; implies single-GPU) - `✓` implemented but single-GPU/CPU only (caveats multi-node) - `🟡` partial support — see the per-line note - `✗` not implemented on the cuPyNumeric distributed path. Behavior on call is version-specific (some unsupported APIs route through host NumPy, others raise an exception) — either way, hot-path use is a migration blocker The cuPyNumeric name is `cupynumeric.` of the NumPy name (e.g. `numpy.fft.fft` ↔ `cupynumeric.fft.fft`). ## Module-Level (290 of 454 implemented) ✓✓ numpy.absolute, numpy.acos, numpy.acosh, numpy.add, numpy.all,
