This lora is to produce the effect of the subject growing bigger. It was trained on mostly male furry videos, so it probably skews towards that in generation.
The alpha version was trained on a larger dataset that included more jerking and pulsing movements to indicate the growth, which tends to be overaccentuated in the generation.
The beta version was trained for more iterations on a smaller dataset that included less visible growth movements, so it tends towards generating things that look like they're just being scaled up.

Generation Tips:
I've noticed that using a mix of both alpha and beta is usually what you want to do. I typically use 0.65 of beta and 0.55 of alpha. Trying to get a sum of a little more than 1 seems to be a good idea, but play around. That means you'll be using four loras for one generation: the high and low alpha and the high and low beta
There's no specific trigger word(s), but you may need to use phrases like "grows bigger"/"grows more muscular"
This seems to need more steps when using the lightx2v/lightning loras, or else you get jerky movements. I typically end up using 10 steps, 5 High, 5 Low
I usually use Euler Simple
