FLUX.2 [Klein]: Towards Interactive Visual Intelligence

Summary

FLUX.2 [klein]: Towards Interactive Visual IntelligenceToday, we release the FLUX.2 [klein] model family, our fastest image models to date. FLUX.2 [klein] unifies generation and editing in a single compact architecture, delivering state-of-the-art quality with end-to-end inference as low as under a second. Built for applications that require real-time image generation without sacrificing quality, and runs on consumer hardware with as little as 13GB VRAM.Try it now for free hereDemo showing editing with FLUX.2 [klein]Why go [klein]?Visual Intelligence is entering a new era. As AI agents become more capable, they need visual generation that can keep up; models that respond in real-time, iterate quickly, and run efficiently on accessible hardware.The klein name comes from the German word for "small", reflecting both the compact model size and the minimal latency. But FLUX.2 [klein] is anything but limited. These models deliver exceptional performance in text-to-image generation, image editing and multi-reference generation, typically reserved for much larger models.What's NewSub-second inference. Generate or edit images in under 0.5s on modern hardware.Photorealistic outputs and high diversity, especially in the base variants.Unified generation and editing. Text-to-image, image editing, and multi-reference support in a single model while delivering frontier performance.Runs on consumer GPUs. The 4B model fits in ~13GB VRAM (RTX 3090/4070 and above).Developer-friendly & Accessible: Apache 2.0 on 4B models, open weights for 9B models. Full open weights for customization and fine-tuning.API and open weights. Production-ready API or run locally with full weights.Note: The “FLUX [dev] Non-Commercial License” has been renamed to “FLUX Non-Commercial License” and will apply to the 9B Klein models. No material changes have been made to the license.Text to Image collage using FLUX.2 [klein]The FLUX.2 [klein] Model FamilyFLUX.2 [klein] 9BOur flagship small model. Defines the Par...
