Notes:

• Created using SD.Next built-in model analyzer
• Number of parameters is proportional to model complexity and ability to learn
  Quality of generated images is also influenced by training data and duration of training
• Size refers to original model variant in 16bit precision where available
  Quantized variations may be smaller
