Coming soon
FLUX 2 is the successor to Black Forest Labs' acclaimed FLUX Pro — the image generation model that redefined prompt adherence and photorealism standards in 2024. Built on a next-generation rectified flow transformer architecture, FLUX 2 is being designed to deliver native 4K image output, faster inference, and an even tighter mapping between text descriptions and visual output. It represents the continued evolution of the technology originally pioneered by the Stable Diffusion research team.
能力说明
FLUX 2 is expected to push image generation quality forward on multiple fronts: true 4K native resolution (4096x4096) without upscaling artefacts, more precise fine-detail rendering for complex textures such as hair, fabric, and skin, and faster generation speed that makes high-resolution batch workflows economically viable. The model will retain FLUX Pro's industry-leading commercial licensing, five-aspect-ratio support, and the deep understanding of photographic technique that makes FLUX images indistinguishable from professional photography at a glance.
最佳实践
If you are already familiar with FLUX Pro on Genace, your existing prompts should transfer cleanly to FLUX 2 — the same prompt engineering principles apply. To take full advantage of FLUX 2's native 4K resolution, include fine-detail descriptors that leverage the extra pixel density: "visible fabric weave", "individual hair strands", "microscopic water droplets". These cues signal to the model that high-frequency detail is important for the shot and yield noticeably superior results compared to FLUX Pro at equivalent sizes.
常见问题
What improvements does FLUX 2 bring over FLUX Pro?
FLUX 2 is expected to introduce native 4K output (4096x4096 and higher), a new training pipeline with expanded high-quality data, and architectural improvements to the rectified flow transformer that further enhance prompt adherence and fine-detail rendering. Early benchmarks suggest FLUX 2 will set a new state-of-the-art for photorealistic and commercial image generation.
Will FLUX 2 still be commercially licensed?
Black Forest Labs has maintained a commercial-friendly licensing model across all FLUX versions. FLUX 2 is expected to continue this approach, allowing outputs to be used in advertising, product design, and published media. Final licence terms will be confirmed at launch.
When will FLUX 2 be available on Genace?
FLUX 2 is under active development at Black Forest Labs. Genace has a direct integration partnership and will add FLUX 2 to the platform as soon as the API is made available. Sign up on the waitlist for priority access.
