The FLUX family of text-to-image models has emerged as a significant player in the AI landscape, with its open models offering unparalleled flexibility and customization options. Unlike most major text-to-image models, which are proprietary and require official APIs for use, FLUX's open models allow anyone to fine-tune them using techniques like low rank adaption, enabling a wide range of creative applications. This openness is reminiscent of the Stable Diffusion model, which was popularized by its openness but has been marred by controversy surrounding its development team and business practices. The new company behind FLUX, Black Forest Labs, has already gained significant traction with its impressive models, and it appears that FLUX will become the go-to open text-to-image generator in the coming months.
