The implementation is available on the main branch and release 0.6.1.
The current runtime uses model-local resource loading instead of treating the v1 spec as the runtime contract. This keeps component selection flexible while the package layout and option surface settle.
The default component mix favors Q4_0 for the large language model and flow transformer, with Q8_0 for the RVQ depth decoder.
BF16, Q8_0, and Q4_0 component variants are included for quality/performance comparison.
Longer generations such as five-minute songs are supported as long-form runs, but they are currently tuned for completion and quality checks rather than realtime throughput.
Memory usage remains an active optimization target for larger durations and alternate component mixes.

Performance Snapshot

Measured on an RTX 5090 with CUDA using a 30-second lyric generation request, 30 flow steps, flow guidance scale 1.7, AR guidance scale 1.5, and top-k 50. Peak VRAM is the observed nvidia-smi process peak during a warmup-plus-measured-request run.

Component mix	Language model	RVQ depth decoder	Flow transformer	RTF	Speed	Peak VRAM
Default Q4/Q8/Q4	`q4_0`	`q8_0`	`q4_0`	0.738	1.35x realtime	9.8 GiB
Q8	`q8_0`	`q8_0`	`q8_0`	0.832	1.20x realtime	13.4 GiB
BF16	`bf16`	`bf16`	`bf16`	1.389	0.72x realtime	19.4 GiB

Quick Start

The prompt is for smoke end-to-end test only.

bash

audiocpp_cli \
  --task gen \
  --family minimax_music3 \
  --model MiniMax-Music3-GGUF \
  --backend cuda \
  --text "A bright pop rock song with clean drums and a clear male vocal." \
  --request-option 'lyrics=City lights are shining low. I keep moving with the glow. Turn it up and let it fly. Sing the melody tonight.' \
  --request-option duration_sec=10 \
  --request-option num_inference_steps=30 \

Components

Default audio.cpp component mix:

language_model_q4_0.gguf
rvq_depth_decoder_q8_0.gguf
transformer_q4_0.gguf
