Notes

• —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 Q40 for the large language model and flow transformer, with Q80 for the RVQ depth decoder.
• —BF16, Q80, and Q40 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.

Quick Start

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