+GGUF conversions of music and speech models for

+inference framework.
+
+## ACE-Step 1.5 XL Turbo (bf16)
+
+`ACE-Step1.5-GGUF/xl-turbo/ace-step-1.5-xl-turbo-bf16.gguf` — 14.2 GB.
+
+The XL DiT is the larger ACE-Step 1.5 transformer: 32 layers of 2560 against
+turbo's 24 of 2048, with 32 attention heads of 128. The file is self-contained
+the way audio.cpp's other ACE-Step GGUFs are — XL DiT, planner LM, text encoder
+and VAE in one file — so it needs no other download.
+
+Converted from [ACE-Step/acestep-v15-xl-turbo](https://huggingface.co/ACE-Step/acestep-v15-xl-turbo)
+(float32 upstream) with `audiocpp_gguf --type bf16`.
+
+### Install
+
+```bash
+python tools/model_manager_v2.py install ace_step_xl_turbo_bf16
+```
+
+### Run
+
+The DiT variant is a load option, so name it explicitly:
+
+```bash
+audiocpp_cli --task gen --family ace_step --model models/ACE-Step1.5-GGUF/xl-turbo \
+  --backend cuda --task-route text2music \
+  --text "warm lo-fi hip hop with a soft rhodes piano" --duration-seconds 60 \
+  --load-option ace_step.dit_model_path=acestep-v15-xl-turbo --out song.wav
+```
+
+Measured on an RTX 5090 (CUDA), 20 s of audio in 15 s including model load.
+
+XL support landed in audio.cpp via
+[PR #235](https://github.com/0xShug0/audio.cpp/pull/235); see
+`docs/models/ace_step.md` there for the full option reference and for rebuilding
+this file yourself.
