They all work well enough on my weak machine with an RX580.

Buuuuuuuuuut, RWKY had some kind of optimization thing going that makes it two or three times faster to generate output. The problem is that you have to be more aware of the order of your input. It has a hard time going backwards to a previous sentence, for example.

So you'd want to say things like "In the next sentence, identify the subject." and not "Identify the subject in the previous text."
