FLUX by Black Forest Labs is a developer-first image model family — priced per generation, not per seat.

Official BFL API / Playground

  • Pay-as-you-go credits: 1 credit = $0.01, no monthly fee
  • FLUX.2 Klein 4B: from $0.014/image (Apache 2.0, commercial OK)
  • FLUX.2 Pro: from $0.03/megapixel (editing $0.045/MP)
  • FLUX.2 Flex: from $0.05/image
  • FLUX.2 Max: from $0.07/image
  • Legacy FLUX.1: 1.1 Pro $0.04, Kontext Pro $0.04, Kontext Max $0.08
  • No free trial on first-party API; prepay $10–20 to start

Self-host (open weights)

  • Klein 4B / schnell: Apache 2.0 → free for commercial use
  • FLUX.2 [dev]: open weights, non-commercial; commercial use needs BFL license
  • Cost = GPU only (cloud ~$0.5–0.75/hr on RTX 4090; ~$0.0002–0.001/image at scale)

Third-party API

  • fal.ai: schnell $0.003/MP, dev $0.025/MP, Pro $0.03/MP
  • Replicate: dev $0.025/image, 1.1 Pro ~$0.04/image
  • Runware: dev $0.0038/image (cheapest metered dev)
  • DeepInfra: schnell as low as $0.002/image (4-step)

Gotchas

  • Megapixel billing: 2MP = 2× cost of 1MP
  • Editing counts input + output MP
  • Strict IP/safety filter even at lowest sensitivity
  • Pro/Max are API-only; dev is not a commercial license

Best pick:​ Klein 4B self-host for volume; FLUX.2 Pro API for production finals; fal for low-latency integration.
