No free plan. The cheapest way in is Pay-as-you-go at $0.03 per megapixel. Consider free alternatives in the image generation category if budget is tight.
FLUX.2 [pro] costs $0.03 for the first megapixel of output, plus $0.015 per additional megapixel of input and output, rounded up to the nearest megapixel. A 1024x1024 image (1 megapixel) costs $0.03, while a 1920x1080 image costs $0.045. Even a small 512x512 output is billed at $0.03 because it rounds up to 1 megapixel. This makes per-image cost highly predictable for production budgeting.
FLUX.2 [pro] is the production-optimized variant with a streamlined pipeline that prioritizes consistency and speed over parameter tuning. Unlike FLUX.2 [dev] or open-weight variants, it exposes no inference steps or guidance scales â the model's internal optimization handles all quality decisions. This zero-configuration approach is designed for teams integrating text-to-image into APIs and automated workflows, where predictable results matter more than experimental control.
Yes. The model is listed on fal.ai with commercial use rights included, and it is offered through the fal.ai partner inference network with Black Forest Labs. This makes it suitable for client work, product imagery, marketing assets, and any revenue-generating application. Always review fal.ai's Terms of Service for the most current licensing details, especially for regulated industries.
JSON prompting lets you specify scene, subjects, style, color palette, lighting, composition, and camera settings (angle, distance, lens) as structured fields instead of natural language. This is particularly useful for controlling multi-subject scenes, precise positioning, and maintaining consistent attributes across complex compositions. For example, you can define subject pose and foreground/midground/background position explicitly, which tends to produce more reliable compositional results than a long prose prompt.
The @ syntax lets you reference uploaded images directly in prompts using tokens like @image1 and @image2. Usage examples include "@image1 wearing the outfit from @image2" or "combine the style of @image1 with the composition of @image2". This provides a more natural multi-image workflow than traditional "image 1 / image 2" index notation, and it is especially useful for style transfer, character consistency, and compositional blending.
