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, for native LoRA/DoRA training with sa3.cpp.

This is a training-only base DiT. Train the adapter on this model, then apply that adapter to Stable Audio 3 Medium 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

The tokenizer, T5Gemma encoder, conditioner, SAME autoencoder, and inference DiT are fetched from the normal medium model set; they are intentionally not duplicated here.
