Underdog Bark 3.0 timeline
Bark 3.0 is a 0.6B English ASR model. The November 5, 2026 revision changes the current weights’ stated license from CC BY 4.0 to CC BY-NC 4.0 while preserving the main packed file’s recorded hash. The author reports a 4.94% seven-set mean word error rate; this is not an independently reproduced result. Download size differs from memory use, and documented runtime support varies by platform. Commercial-use inquiries have a separate contact in the model notice.
