Imagen 4 sampleFlux 2 and Imagen 4 are both top-tier in 2026 but represent opposite philosophies. Flux 2 is the open-source flag-bearer — Apache 2.0, self-hostable, no fine-print. Imagen 4 is the polished closed-source product from Google DeepMind with the cleanest photorealistic output anyone ships.
Choose Flux 2 when self-hosting freedom, commercial use without restrictions, and sub-2-second speed matter most.
Try Flux 2 FreeChoose Imagen 4 when you want Google-grade photorealism with zero setup, free in AI Studio, and don't need to host the model yourself.
