Flux

Image gen from the Stable Diffusion creators. Best photorealism available, good text rendering, and Kontext lets you edit existing images with plain English.

About Flux

Flux comes from Black Forest Labs — the same people who built Stable Diffusion. It's a family of models: Schnell (free, under 2 seconds), Dev (open-weight, good for experiments), Pro (best quality), and Kontext (edit existing images with natural language). Kontext is the one worth paying attention to. Upload a product photo, tell it to swap the background or change the lighting, and it keeps everything else intact. Good for creating variations of brand assets without starting from scratch. Photorealism is the best in the field right now. Text rendering is solid — not perfect, but better than most. Flux 2.0 added Klein models that generate in under 1 second. Pricing: $0.04/image for Pro, and Schnell is Apache 2.0 licensed if you want to self-host.
