What the quality score means
Quality is a reference free routing signal from 0 to 100. It helps compare our own model runs. It is not an SDR score and should not be compared with a different website or paper.
AI stem separation model benchmark
AudioStem.ai tests its separation models against a licensed audio corpus inside the same worker images used for customer tracks. The public benchmark reports quality, reconstruction, isolation, processing time and estimated compute cost.
Measured in production containers
The nightly test runs inside the actual container images that process tracks. Models that have not completed a valid run are shown as unavailable instead of being removed from the report.

The interactive table can be sorted by quality, reconstruction, isolation, time and estimated cost after the page loads.
