FLUX Image Generation Models
Overview
FLUX is made by Black Forest Labs (BFL). The original FLUX.1 trio (Pro, Dev, Schnell) has been superseded; BFL's docs now recommend FLUX.2 for new projects, and FLUX 3 Image is the newest line.

Use it for |

| FLUX 3 Image | flux-3-image |
Newest image model: text-to-image, editing, up to 10 references, bounding-box layouts |
| FLUX.2 [max] | flux-2-max |
Highest quality, grounded web search for real-world facts |
| FLUX.2 [pro] | flux-2-pro-preview (latest) or flux-2-pro (pinned snapshot) |
Production quality, hex-color control, up to 4MP, multi-reference editing |
| FLUX.2 [flex] | flux-2-flex |
Fine-grained control over generation settings |
| FLUX.2 [klein] | flux-2-klein-4b, flux-2-klein-9b-preview / flux-2-klein-9b |
Sub-second, cheap, open weights (4B Apache 2.0, 9B non-commercial) |
| FLUX.1 [dev] / [schnell] | via fal.ai / Replicate | Legacy; LoRA ecosystem (Dev), 4-step speed (Schnell, Apache 2.0) |
| FLUX1.1 [pro], Kontext | flux-pro-1.1, Kontext endpoints |

Use -preview endpoints for the latest improvements and the unsuffixed ones when you need reproducible output. Prices are in BFL credits (1 credit = $0.01) and change; check bfl.ai/pricing. FLUX.1 [dev] weights and FLUX.2 [klein] 9B / [dev] are non-commercial licensed: commercial use goes through a paid API or license.
