| # Stable Audio 3 Medium Base DiT — GGUF for sa3.cpp |
|
|
| F16 and F32 GGUF conversions of the training DiT from |
| [stabilityai/stable-audio-3-medium-base](https://huggingface.co/stabilityai/stable-audio-3-medium-base), |
| for native LoRA/DoRA training with [sa3.cpp](https://github.com/betweentwomidnights/sa3.cpp). |
|
|
| This is a training-only base DiT. Train the adapter on this model, then apply that adapter to |
| [Stable Audio 3 Medium](https://huggingface.co/thepatch/stable-audio-3-medium-GGUF) for inference. |
| Do not use the post-trained/ARC medium DiT as the training base. |

| ## Files |
|
|
| | file | purpose | |
| |---|---| |
| | `stable-audio-3-medium-base-dit-1.5B-v1.0-F16.gguf` | recommended frozen training base | |
| | `stable-audio-3-medium-base-dit-1.5B-v1.0-F32.gguf` | CPU/reference validation | |
| | `SHA256SUMS` | release checksums | |
|
|
| The tokenizer, T5Gemma encoder, conditioner, SAME autoencoder, and inference DiT are fetched from |
| the normal medium model set; they are intentionally not duplicated here. |

|
|
| - Source revision: `b32993f73c3bdc3864043a72d8032606bba737c8` |
| - Conversion: `tools/convert_dit.py --variant medium --training-base`, then `tools/quantize_gguf.py` for F16 |
| - Relationship: tensor rename/serialization and precision conversion only; no retraining |
