FluxGym: Low-VRAM Training GUI for flux lora
Posted on September 9, 2024 - General

Ever wanted to train FLUX LoRAs but got stuck because of high VRAM requirements? Say hello to Flux Gym.
UI
What's Flux Gym All About?
Flux Gym is a no-nonsense web UI for training FLUX LoRA models. The best part? It works with lower VRAM setups - we're talking 12GB, 16GB, and 20GB.
Here's the deal:
- It's built on the AI-Toolkit project (shoutout to @multimodalart for the slick Gradio UI)
- Under the hood, it's powered by Kohya Scripts for the actual training
Why Flux Gym?
Look, I get it. Training FLUX LoRAs can be a pain:
- AI-Toolkit is great, but it needs 24GB VRAM. Ouch.
- Kohya Scripts are flexible, but command line? Not everyone's cup of tea.
Key Features
- Works with 12GB, 16GB, and 20GB VRAM setups
- Dead simple web interface
- Powered by Kohya Scripts (so it's expandable)
