Kokoro-82M — bf16 (MLX)

Kokoro-82M converted to bfloat16 for MLX inference on Apple Silicon.

Converted from mlx-community/Kokoro-82M-bf16 revision a71e4d38b236d968966a2002c4c895dbd12b1c3c — whose safetensors are stored as float32 despite the repo name. This conversion halves the download (156 MB vs 312 MB) with no quality change: the model's architecture (ALBERT encoder + BiLSTM + ISTFTNet vocoder) runs identically at bf16 precision on Apple Silicon's native bf16 hardware.

Provenance

Source: mlx-community/Kokoro-82M-bf16 @ a71e4d38
Original model: hexgrad/Kokoro-82M (Apache 2.0)
Conversion: F32 → bfloat16 via mlx.core (no quantization, no pruning)
Every original F32 tensor verified as float32 before conversion
Original digests cross-checked against the pinned manifest

Usage with M1K3

These weights are used by M1K3's Kokoro neural voice (M1K3Kokoro target). The app loads them via MLX.loadArrays — dtype is handled transparently by mlx-swift.
