Models in this field

220 entries

Includes public test results for models used here and elsewhere. The complete source table is shown by default; conditions and metrics can also be selected for comparison. Scores from different test conditions are not directly comparable.

Only records with verified public inference implementations and matching weights are shown; algorithms requiring no weights are also eligible. Closed services, unreleased weights and unmatched experiment versions are excluded. This is not an all-model leaderboard.

Public weights do not establish a fully open-source license. Expand the data for declared weight licenses and access conditions. Undeclared licenses are marked separately.

BenchmarkRanking category

Frozen 2026-09-13 evaluation: 285 inputs, 855 inferences. References exist for 208 GuitarSet and 48 SWD inputs; 29 local inputs have no independent truth and no accuracy score. All 55 groups are selectable, including solo, style, performer and reference type: performed, instructed and human. WCSR weights eligible duration; macro averages tracks; bar scores use reference bars. Expand each metric’s included/excluded duration. Omnizart raw and CSV remain separate. Results do not guarantee arbitrary-mix accuracy or zero training overlap.
