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.

File	Tensor inventory	SHA-256
`moss-soundeffect-2.0.gguf`	198 BF16, 113 FP32, 0 FP16	`676d3ead6b12e99ecff0a3c29172f0f3571b17834724b19559c4f8572135a8de`
`moss-soundeffect-2.0.extras.gguf`	376 BF16, 597 FP32, 0 FP16	`f905b2bb3be6e21908778e3d8ef8b0d06dc419cab1d3bb7613a29dc21d924b64`

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.

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.
