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.
On the Sogni API you pay per render in Spark (1 Spark = $0.005). Prefer a flat rate? The Sogni app runs FLUX.2 [dev] and 100+ other models credit-free under fair use.
| Configuration | Spark | USD |
|---|---|---|
| 1024 × 1024 · 20 steps | 4.15 Spark | $0.021 |
| 1024 × 1024 · 28 steps | 5.80 Spark | $0.029 |
One Sogni API key reaches every model on the Supernet — call FLUX.2 [dev] by id.

Most platforms ration credits or rent a cloud GPU by the hour. Sogni gives you a flat monthly price for credit-free fair-use generation, powered by a creator-owned GPU network — or per-render Spark pricing if you'd rather pay as you go via the API.
One flat price in the app. Generate under fair use without a per-image meter.
Image, video, music, and language models in one workspace and one API key.
Prefer pay-as-you-go? Call FLUX.2 [dev] by id and pay in Spark.
Runs on a decentralized GPU network where workers share subscription revenue.
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.
From 4.15 Spark ($0.021) per render on the Sogni API (1 Spark = $0.005) — or unlimited under fair use on a flat monthly Sogni plan.
