This is an old SD1.5 lora I made several years ago. I wanted to upload it in the meantime while I work on porting it to SDXL. The training is a bit lopsided, so some characters are weakly trained, mainly Eleanor and also Theodore and Jeanette are a little weak.
You'll want to mostly use 0.7 weight. You can bump it up to 0.8 if the accuracy isn't good enough, and in cases like Eleanor, you may need to use 1.0 weight along with supporting tags to get the shape down, and then inpaint or img2img afterward with a lower weight.
Tags are as follows:
CGI is a mandatory tag.
Use the first name of each desired character. Such as Alvin, Simon, Theodore, Brittany, Jeanette, and Eleanor.
Add Chipmunk or Chipette according to the desired character's gender. It might still work otherwise, but that's how the training data was tagged.
I recommend using hires fix on a 1.5 multiplier. Or just generate at 1536 for one or both of the width and height.
