What each one is
FluxGym
FluxGym provides a dead-simple web interface to train FLUX LoRAs on consumer GPUs, hiding the complexity of the underlying training scripts.
- Trains LoRAs on 12GB VRAM
- Simple web UI, no config files
- Built on proven training backends
AirCube
AirCube is a hosted service putting third-party generation models - Sora, Veo, Kling, Flux and ElevenLabs among them - behind one API key, used from a REST endpoint or a browser generator; nothing runs locally. Its FAQ says pricing is usage-based on one invoice, free to start without a credit card. Note before using it: the FAQ says inputs are sent to the underlying model providers, whose own terms, data handling and output rules apply.
- One API key and one bill across every model on the platform, per the site's FAQ.
- Usable from the browser generator or a REST endpoint; the page shows a cURL example.
- Per the FAQ, all models share one request schema, so switching model is one parameter.
