Supertonic-3 fp16 ONNX (availability mirror)

This repository redistributes existing model weights unchanged. It exists so that a published mobile application has a distribution endpoint whose availability we control. No model was trained, fine-tuned, or modified here.

Provenance


Original model	Supertone/supertonic-3 — Copyright (c) 2026 Supertone Inc.
fp16 ONNX conversion	Kyumdroid/supertonic-3-quant
This repository	Byte-identical copy of the above conversion. No files were altered.

The fp16 conversion was performed by Kyumdroid using onnxruntime.transformers.float16.convert_float_to_float16 with keep_io_types=True (fp32 I/O for SDK compatibility) and op_block_list=['Cast']. See the upstream conversion notes for detail.

Every file in this repository has been verified by SHA-256 against the upstream conversion repository. All 16 files match.
