Summary

A short note on which base models image LoRAs have been trained on over time: first Stable Diffusion, then Flux, and now Krea 2. It helps you pick a current base model for image LoRA fine-tuning.

Key points

• Image LoRA base models went SD → Flux → Krea 2
• Krea 2 is presented as the newest base model for image LoRAs
