Questions
FLUX.3 on Leap, answered.
- Is this the real FLUX.3?
- Yes. Leap sends your request to Black Forest Labs's model through its provider and gives you back what it makes. Switch to any other model in the same studio when an idea needs it.
- What does it cost?
- In dollars, per run: the provider's list price plus 10%. You see the exact price before every run, a run that fails costs nothing, and there is no subscription. Every model's price is on the pricing page.
- Do I need a Black Forest Labs account?
- No. One Leap account and one balance run FLUX.3 and every other model, in the studio, through the API and from your agents.
- What happens to what I make?
- It stays in your library while your account is active, ready to use anywhere.

A lone woman in her fifties, Faroese, weathered face with windburned cheeks and pale eyes, grey-blond hair whipped by the wind, in a bright yellow oilskin fishing jacket, stands on a black basalt sea wall in the Faroe Islands as a storm wave explodes white behind her; she is small against the sea, and the turf-roofed houses of a cliff village sit high behind her. Desaturated slate blue and black, with the yellow jacket as the only colour. Typography: the title SALT LINE huge in a tall, condensed, bold sans serif in white across the upper third, tightly set; at the bottom the tagline \"The sea keeps what it takes.\" and below it, small, \"IN CINEMAS THIS NOVEMBER\". Film grain, offset print texture, a real one-sheet composition with generous negative space. No other text." } }'
