Best voice cloning models for a 64GB graphics card
A leaderboard of the best voice cloning models for a 64GB graphics card (with 32GB of system RAM). The best one that runs on it right now is dots.tts SOAR 2B, followed by LongCat-AudioDiT-3.5B and dots.tts MF 2B (MeanFlow, NFE 4). Models are ranked on how clear the cloned voice is and how much it sounds like the original speaker. Models that run on it show the download that fits and the command to run it.
Scores use reviewed voice cloning evaluations only. Compare scores within this task. Models without task measurements are excluded.
