Notes
This is a 64 dim locon. Compared to the smaller 24 dim locons, this seems to have increased flexibility. In the context of SD15, this is a win-win all around. The size is still under 100mb, so it's smaller than the 96 dim loras I started with. But in SDXL land, this size increase will push it into unwieldy territory.
I've heard that some people resize their loras to shrink them in an attempt to retain quality at a smaller file size. I've never done that before, but I think it's worth some experimentation. Perhaps I'll redo one of my earlier 24 bit locons and do a comparison to see if the larger dim does in fact increase flexibility (and perhaps overall quality).
The other change I made that may have had this impact was the move from fp16 to bf16, which has increased precision with smaller numbers.
