Introduction of fish-speech-s2-pro-fp8

Model Details of fish-speech-s2-pro-fp8

Fish Audio S2 Pro — FP8 (AEmotionStudio Mirror)

FP8 weight-only quantization of Fish Audio S2 Pro .

Details
Property Value
Source model fishaudio/s2-pro
Quantization Per-row symmetric FP8 (float8_e4m3fn)
Linear layers quantized 201
FP8 params 4.048B
BF16 params 0.514B
Model size 4.73 GB
VRAM requirement ~12 GB
How it works

All nn.Linear weight matrices are quantized to float8_e4m3fn with per-row float32 scale factors. Non-linear weights (embeddings, layer norms, codec) remain in bfloat16. No external quantization library is needed — dequantization is pure PyTorch:

W_bf16 = W_fp8.to(torch.bfloat16) * scale
License

This model inherits the Fish Audio Research License . Free for research and non-commercial use. Commercial use requires a separate license from Fish Audio.
