Our data shows the ratio of logged to registered models 
is 2.9 : 1 as of January 2023. This means that for roughly 
every three experimental models, one model will get 
registered as a candidate for production. This ratio has 
improved significantly from just a year prior, when we 

saw that for roughly every five experimental models, one 
was registered. Recent advances in ML, such as improved 
open source libraries like MLflow and Hugging Face, have 
radically simplified building and putting models into 
production. The result is that 34% of logged models are 
now candidates for production today, an improvement 
from over 20% just a year ago.
