Acentaur MLX model packages

Official public release-distribution repository for the persistent MLX packages used by ACENTAUR 1.0 on Apple Silicon. ACENTAUR Setup downloads only the selected revision-pinned package paths. These files are derived from the official ACE-Step 1.5 weights and retain the upstream MIT license.

These packages are not intended for direct use with LM Studio, Transformers, Diffusers, generic MLX model loaders or Hugging Face Inference Providers. Get ACENTAUR and product information at https://www.einaux.com.

The packages use Acentaur's versioned internal checkpoint contract. Each package contains a manifest.json that pins its upstream model revision and source file metadata. Download and installation are managed by ACENTAUR Setup; cloning the complete repository is unnecessary.

Package	Acentaur role	Stored dtype	Payload bytes
`acestep-v15-turbo`	ACE 2B Turbo DiT and conditioning	float16 + source	4,787,821,153
`acestep-v15-sft`	ACE 2B SFT DiT and conditioning	float32 + source	7,938,739,105
`acestep-v15-base`	ACE 2B Base DiT and conditioning	float32 + source	7,938,739,083
`acestep-v15-xl-turbo`	ACE XL Turbo DiT and conditioning	float16 + source	11,611,541,334
`acestep-v15-xl-sft`	ACE XL SFT DiT and conditioning	float32 + source	19,949,336,105
`acestep-v15-xl-base`	ACE XL Base DiT and conditioning	float32 + source	19,949,336,105
`vae`	Shared native MLX VAE	float32	674,673,591

Total Safetensors payload: 72,850,186,476 bytes.

The planner and embedding assets remain immutable upstream packages rather than converted DiT payloads:

Shared asset	Role	Upstream revision	Repository bytes
`Qwen3-Embedding-0.6B`	Shared text embedding	`ACE-Step/Ace-Step1.5@19671f406d603126926c1b7e2adc169acbcade22`	1,207,471,006
`acestep-5Hz-lm-0.6B`	Low-memory ACE planner	`ACE-Step/acestep-5Hz-lm-0.6B@148d8ea0225bdab342ee1ae3a354275ccd60ca80`	1,364,198,888
`acestep-5Hz-lm-1.7B`	Default ACE planner	`ACE-Step/Ace-Step1.5@19671f406d603126926c1b7e2adc169acbcade22`	3,755,412,617
`acestep-5Hz-lm-4B`	Parked Large ACE planner; not downloaded by release Setup pending an upstream MLX fix	`ACE-Step/acestep-5Hz-lm-4B@0a3ec94b557aea7d508da38b31cfe7341f6ff737`	8,426,085,346

Provenance

The source repositories and exact revisions are recorded in source-revisions.json and repeated inside each package manifest. Original PyTorch DiT shards are not included. Public tokenizer, embedding and planner assets that Acentaur consumes directly are intentionally outside this repository. The pinned 4B provenance remains recorded, but release Setup does not download it while its Apple-Silicon MLX path is parked.

The newly added regular SFT package was built from the immutable upstream revision c410d249e71ea9385a7b586865e65b1473e1098d. Its converted payload is:

File	Bytes	SHA-256
`acestep-v15-sft/model.safetensors`	6,301,886,377	`3a8bce909ed0becccbfb54199f4cdbf3f7131fcdc5f232db48e929f47bdd78fd`
`acestep-v15-sft/conditioning.safetensors`	1,636,852,728	`0d94bfca037e3039f34b5b8652aa19b3658627e39a208bf79d27aae92d04e578`

Validation

Before upload, all 13 Safetensors files were opened successfully and checked against their manifests for exact file size and tensor count. The five previously shipped DiT packages (turbo, base, xl-turbo, xl-sft, and xl-base) have passed Acentaur's runtime/parity matrix. The regular sft package passed focused ACENTAUR M5 runtime smokes with No LM and the 0.6B planner on 2026-08-13. Those smokes establish runtime operation, not final listening-quality parity.

Public, anonymous revision-pinned download is part of the ACENTAUR 1.0 Setup and release contract. Changing the repository to private would be a breaking distribution change and requires a new authenticated delivery contract.
