Why it costs less

FLUX 3 Image Klein: open weights, for less

An open-weights model has no lab API price in between: what you pay follows what serving it costs.

01

Open weights

FLUX 3 Image Klein is Black Forest Labs's open-weights model: no lab API price sits in between, so what you pay follows what serving it costs.

02

Our own GPU inference

For open-source models, our own GPU inference — optimized kernels, warm pools and per-model tuning — makes generation several times faster and lowers the cost further.

03

Automatic routing

Every FLUX 3 Image Klein request is routed to the most cost-effective healthy route, with live health checks and failover.
