ACE-Step MLX Planner 1.7B (fp16)

MLX-compatible fp16 package for the ACE-Step 5Hz planner LM used by optional Phase 6 LM-conditioning. This repo is shared by the base turbo and XL-turbo ACE-Step MLX model packages so the planner is not duplicated in every DiT repo.

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. For fp16 DiT variants, the FSQ projection and AudioTokenDetokenizer tensors are inline in dit/model.safetensors, so no detokenizer sidecar is needed.

Source attribution

The planner LM is the ACE-Step 5Hz planner, a fine-tune in the Qwen3-1.7B family. Qwen3 is Apache 2.0 licensed. This package changes only the on-disk layout and MLX-compatible safetensors dtype representation; it does not change the model architecture or learned parameters.

NOTICE

This package carries the upstream Qwen3 NOTICE obligation. See the upstream Qwen3 model card for the canonical NOTICE text and verify the latest version before re-redistribution.
