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.
Runway
Runway is a browser-based AI video platform used by filmmakers, social media creators, and marketing teams to generate, edit, and transform video with text and image prompts. Its Gen-4 Alpha model produces short video clips from text or images, while traditional editing tools sit alongside AI features in one workspace. Output quality impresses at short durations, but longer or complex scenes still require significant iteration.
