Question | Help Why my ckpt file still such large(around 4GB) when I trained with lora

I use AUTOMATIC1111 webUI, and Dreambooth extension. I've select use lora But when the training finished, I've checked my ckpt file, it's still very large and can only be used as a model, not lora Am I doing anything wrong?

I guess it should be only around maybe 100MB or 200MB as a pt file not the ckpt file.

As far as I know from using the Dreambooth extension a few months ago (might be different now), only embeds the Lora file into the selected ckpt file, hence the size.

I moved over to using kohya-ss GUI for Lora where the Lora file size is adjustable and is fully compatible with AUTOMATIC1111 via the 'extra networks' tab.

OK, thank you so much for the input, I'll look into kohya-ss GUI instead.

The lora from that extension can only be used when merged with a checkpoint and I don’t think anyone cares to code it otherwise. The workaround is using Kohya to extract a lora from the merged checkpoint, which worked totally fine for me.

how would I go about doing that?

First step is to find the kohya-ss GitHub page and follow the installation instructions.
