I've enjoyed using it for free, but not sure it's worth the $10/mo yet. When it works great, it's a nice-to-have for speeding up development but has yet to give me anything I wouldn't be able to just write myself. And when I wish it would give me the answer to something I don't know how to do, it spits out something very wrong. Also feels kind of icky to train on open source projects and then charge for the output.
How would you feel if they just provided the software without the model, assuming you could train it yourself on open-source code in an instant?
