Frequently asked questions
Black Forest Labs FAQs
What is the difference between FLUX 1.1 Pro Ultra and FLUX.1 Dev?
FLUX 1.1 Pro Ultra is a commercial API model offering the highest quality output at up to 4MP resolution. FLUX.1 Dev is an open-weight model available for self-hosting and fine-tuning, with slightly lower quality than Pro Ultra but full weight access.
How does FLUX compare to Stable Diffusion 3.5?
FLUX consistently outperforms SD 3.5 on image quality benchmarks, particularly for photorealism and prompt adherence. FLUX Schnell is also significantly faster than SD 3.5 for equivalent quality.
Where can I access FLUX models?
FLUX models are available via the BFL API directly, and through Replicate, fal.ai, Novita AI, and other inference platforms. FLUX.1 Dev and Schnell weights are also available on Hugging Face for self-hosting.
Runway FAQs
How is Runway priced?
Runway charges per second of generated video. Gen-4 is $0.100/second and Gen-4 Turbo is $0.050/second. See runwayml.com/pricing for current rates.
What is Gen-4?
Gen-4 is Runway's latest video generation model, producing cinematic-quality output from text or image prompts. It is used in professional film, advertising, and visual effects production.
