LuxTTS — MLX weights (fp32)
LuxTTS converted to MLX-native safetensors, for Apple silicon. Same model, same precision — a key-remap and a conv-layout transpose, nothing retrained and nothing quantized.
Upstream ships model.pt (torch) and ONNX graphs. Neither loads in MLX, so
every MLX consumer had to run the conversion itself and keep the result
somewhere local. This repo is that result, published once.

fp32 on purpose. fp16 halves the download and is indistinguishable on a long, clean reference — and audibly worse on a short one. Blind A/B on a clone made from an 8-second phone recording: 4 of 8 fp16 renders had artefacts a listener rejected, against 0 of 8 at fp32. If you are cloning from short user recordings, use these.

let model = try await LuxSpeechModel.load(from: weightsDirectory)
The directory needs all four files side by side.
