I’m training a LoRA model using Flux on pictures of a person in Kohya for 200 epochs, 1 repeat, rank

I’m training a LoRA model using Flux on pictures of a person in Kohya for 200 epochs, 1 repeat, rank 128, and batch size 1. The model turns out to be 2.5 GB, but I have a strict limit — the model needs to be under 1 GB. How can I make the model smaller so I can run it later on fal.ai? I understand that I can lower the rank, but what other approaches are there?
