Okay let's talk terminology

I meant the useable application as a for example chat bot.

The model itself is useful as far as it enables me to understand the underlying logic of the whole thing right? But without the data and I guess a training period with it I can't use it if I understood it correctly.

If I am right with the above this wouldnt make it useful as in I can reproduce it as a functioning application and I wouldn't call that opensourve in my understanding of the word.
