PowerBeef02/Qwen3-TTS-12Hz-1.7B-Base-4bit
Vocello production artifact. Derived from
mlx-community/Qwen3-TTS-12Hz-1.7B-Base-4bit
at revision 37e955a1deb861c088ae5f3a67043185f3d1a60c (itself an MLX conversion of the
corresponding Qwen/Qwen3-TTS checkpoint), with one change:
the 622 MB BF16 talker.model.text_embedding tensor is quantized to affine 8-bit
(group size 64) by Vocello's pinned conversion tooling
(scripts/convert_text_embedding_8bit.py, python-mlx 0.32.0). Every other tensor is
byte-identical to the source revision.
Measured on the Vocello support floor (Mac mini M2 8 GB): about 278 MB less resident
memory and 292 MB less download per Speed artifact at parity real-time factor, with clean
deterministic audio QC. Measurement details live in the
Vocello repository (benchmarks/OPTIMIZATION.md §N).
These files are consumed by Vocello's fail-closed model catalog, which pins this repository at an exact revision with per-file SHA-256 digests.
