# NVIDIA's Parakeet TDT 0.6B v2 (English speech recognition), the ONNX export of istupakov at a
# pinned revision: NeMo's 128-bin mel features, the full precision encoder (its weights in the
# .data file beside it; the 8-bit encoder is slower on CPUs without fast integer kernels) and the
# decoder/joint network in both precisions. Data only; www-apps/attendant's attendant-speech runs
# it on sci-libs/onnxruntime. The version is the export revision's date (2026-02-17).
