What they are
Flux
Flux is a family of text-to-image models from Black Forest Labs, the team behind Stable Diffusion. It generates high-resolution, photorealistic and stylized images from text prompts, with strong prompt adherence and fine detail. Creators, designers, and developers use it via API or third-party platforms. Flux produces genuinely impressive output, but there is no native consumer app, so getting started requires some technical setup or a compatible host.
Leonardo AI
Leonardo AI is a browser-based image generation platform that produces high-quality visuals using a range of fine-tuned models, including its own proprietary ones. It is used by game developers, illustrators, and content creators who need consistent characters, concept art, or marketing assets at scale. The platform offers more model control than most consumer tools, though the credit system can feel restrictive on the free tier.
