# HeartMuLa 3B quality test
|
|
|
|
Reversible A/B test of the public
|
|
`HeartMuLa/HeartMuLa-oss-3B-happy-new-year` model with
|
|
`HeartMuLa/HeartCodec-oss-20260123`.
|
|
|
|
The model and codec are deliberately split across Athena's GPUs:
|
|
|
|
- HeartMuLa BF16: RTX 5080 (`cuda:0` inside the container)
|
|
- HeartCodec FP32: RTX 3060 (`cuda:1` inside the container)
|
|
|
|
The public model does not yet support reference-audio conditioning. Pure
|
|
instrumental generation is exposed as an explicitly experimental option.
|
|
Generated files are lossless 48-kHz WAV files under `/data/music/heartmula`.
|
|
|
|
The container intentionally has no `com.mike-ai.music-worker` label while it
|
|
is being evaluated. This prevents it from conflicting with the production
|
|
profile controller's single ACE-Step worker.
|
|
|
|
## Checkpoints
|
|
|
|
The expected persistent layout on Athena is:
|
|
|
|
```text
|
|
/data/models/heartmula/ckpt/
|
|
├── HeartMuLa-oss-3B/
|
|
├── HeartCodec-oss/
|
|
├── gen_config.json
|
|
└── tokenizer.json
|
|
```
|
|
|
|
## Test operation
|
|
|
|
Only after the current music worker has been stopped:
|
|
|
|
```sh
|
|
cd /opt/mike-ai/heartmula-3b
|
|
docker compose up -d heartmula-test
|
|
docker compose logs -f heartmula-test
|
|
```
|
|
|
|
The temporary test UI listens locally on port `7863`. During the listening
|
|
test it is proxied through Athena's existing WireGuard gateway; permanent
|
|
dashboard/gateway integration is deliberately deferred until the audio has
|
|
been accepted. Stop it with:
|
|
|
|
```sh
|
|
docker compose down
|
|
```
|
|
|
|
Do not remove ACE-Step or change the dashboard/profile controller until the
|
|
A/B test has been accepted.
