FLUX 3 is Black Forest Labs’ flagship: photoreal generation and reference-based edits, from 768-pixel drafts to 4K, billed by the megapixel.
FLUX 3 is the successor to FLUX.2 Pro from Black Forest Labs, the lab behind the FLUX family. It generates from a prompt and edits from up to eight reference images, with a framing set that runs from 21:9 to 1:2.
Billing is per megapixel, so a 768-pixel draft costs a fraction of a 1K render and 4K costs sixteen times as much. Draft small, then re-render the keeper at the size the layout needs. FLUX 3 Klein is the small, fast sibling for cheap iterations.
From 6 tokens ($0.06) per image; 10 tokens ($0.10) at the default settings.
| Settings | Tokens | Price |
|---|---|---|
| 768 | 6 | $0.06 |
| 1K | 10 | $0.10 |
| 2K | 37 | $0.37 |
| 4K | 135 | $1.35 |
Prices come from the live catalog at $0.0100 per token, the pay-as-you-go rate; subscriptions include tokens at a lower rate. The exact price is shown before you generate, and a failed generation is refunded.
