Licensing is a critical question that is often not considered. Code trained on non-permissive code (think Oracle API's) has very significant risk, ask Google.

Licensing is a critical question that is often not considered. Code trained on non-permissive code (think Oracle API's) has very significant risk, ask Google. We took a different tact three years ago in building Tabnine BUT went with only fully permissive code for training, ability to train on your own code base, and zero sharing of your completions. Also we give the developer the flexibility to adjust the length of completions if you want faster shorter suggestions.
