From the Hugging Face model README
ACE-Step MLX Planner 4B FP16
MLX-compatible fp16 package for the ACE-Step 5Hz planner LM used by optional Phase 6 LM-conditioning. Larger planner for high-RAM / desktop runs (higher-fidelity planning).
The planner is shared by the base turbo and XL-turbo ACE-Step MLX model packages so it is not duplicated in every DiT repo. The 5Hz planner ships in three sizes (0.6B / 1.7B / 4B); the host app selects a size by available memory.
Usage
Baseline generation does not need this repo. To enable Phase 6, pass the
planner snapshot to the generator with --lm-weights. For Q4 DiT variants,
also pass the model repo's bundled detokenizer.safetensors as
--lm-conditioning-checkpoint.
Source attribution
The planner LM is the ACE-Step 5Hz planner, a fine-tune in the Qwen3 family (Apache 2.0). This package changes the on-disk layout.
NOTICE
This package carries the upstream Qwen3 NOTICE obligation. See the upstream Qwen3 model card for the canonical NOTICE text.
