 ## Performance
 
-TBD, here will be a link and a summary of model sizes and performance metrics.
-
-TLDR for now: our models work ok on CPUs with RTF < 1. Each model weighs about ~200MB. We have succeeded in compressing our models up to 50MB with some loss of quality. Our aspirational goal is first to achieve 50 MB w/o quality loss and then scale to 10-20MB or even provide some compact variants of our EE models.
