# 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.

## Provenance

- 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
