MOSS-SoundEffect-v2.0 BF16 GGUF for OpenMOSS

GGUF weights for OpenMOSS-Team/MOSS-SoundEffect-v2.0, converted for the OpenMOSS C++/GGML runtime.

Precision correction

Both files in this revision are FP16-free. The official pipeline runs the model with torch.bfloat16; the previous GGUF conversion stored the Qwen3 text encoder, DiT, and most VAE tensors as FP16. This rebuild keeps ordinary learned weights in BF16 without an intermediate FP16 cast. One-dimensional normalization/bias tensors and the VAE's numerically sensitive Snake parameters remain FP32.

Both files must remain beside each other. The backbone is the Qwen3 text encoder; the sidecar contains the diffusion transformer, DAC VAE decoder, and scheduler metadata.

Source revision

  • SoundEffect: OpenMOSS-Team/MOSS-SoundEffect-v2.0@e35df4d82fbe87fcd5d14e5d100e349c0c3c076d
  • Converter/runtime base: pwilkin/openmoss@d1f2976a89fd51bf949d28320af401e523b78c67, with BF16-preserving sidecar conversion

Validation

  • Tensor audit: zero FP16 tensors in both files.
  • Vulkan: complete 100-step generation and VAE decode of a three-second footstep pilot.
  • CLAP semantic ranking gave the intended footstep label 0.9367 probability, ahead of the nearest alternate at 0.0445.
  • Waveform QA found no clipping, late transient, or leading/trailing-silence warning.
