I'm pretty sure that this is some kind of scientific achievement that I do not fully understand but the real world use cases for this model seem to be very limited.

I gave it two tasks. "Create a new and original story in 500 words" and "Write a Python console game". Both of those resulted in an endless loop with the model repeating itself

I'm honest. Given that a 1B Granite nano model has only little problems (word count) with such tasks and given that VibeThinker is announced as a programming model it's disappointing to see a 1.6B model fail multiple times.
