Mermaid was done with an entirely different dataset strategy and is a significant improvement over the first versions of the rest of the Rearz brands which is why version 1 was skipped.

Version 2 (currently just Mermaid) has far greater pattern and shape consistency with a bit of overtraining issues that should be resolved by the next lora. It does create two tape diapers more than preferred, but it's not bad looking despite not being true to the real life product.

Version 1 all have very weak consistency and shape. They were fine as a proof of concept, but overall not great.

Any diaper generated will be the brand from the lora.
