flux2_dev_fp8 Black Forest Labs’ flagship — top-tier fidelity with up to six reference images.
No GPU. No setup. Cancel anytime.
FLUX.2 [dev] is the highest-fidelity open-weights image model on the Supernet. It excels at photorealism, complex composition, and prompt adherence, and accepts up to six reference images for guided generation and editing in one pass.
It is the default model for the REST workflow API’s generate_image tool. Budget roughly two minutes per full-quality render; drop the step count for faster drafts.
Use pay-as-you-go Spark packs for each render (1 Spark = $0.005), or choose a flat-rate Sogni plan for credit-free fair-use generation in the app.
| Configuration | Spark | USD |
|---|---|---|
| 1024 × 1024 · 20 steps | 4.15 Spark | $0.021 |
| 1024 × 1024 · 28 steps | 5.80 Spark | $0.029 |
