| VRAM (FLUX.1) | ai-toolkit ships a 24GB example config (train_lora_flux_24gb.yaml) | |
| Overview | GUI + CLI trainer with a broad model list; good VRAM use and speed, but more settings to configure. | The long-standing kohya training scripts (also used by the kohya_ss GUI); strongest for SD1.5/SDXL-era models. |
If you want the quickest start with a web UI, pick ai-toolkit. If you already use a script-based trainer's ecosystem, stick with it.
