AI Images Under a Second: New Models Shatter Speed Records

Black Forest Labs, a German AI startup founded by former Stability AI engineers, has released FLUX.2 [klein], a pair of efficient AI image generation models emphasizing speed and reduced compute needs. These models can generate images in less than a second, even on consumer-grade GPUs. The 4 billion parameter version is available under an Apache 2.0 license, allowing for unrestricted commercial use without licensing fees.

The [klein] series, which includes 4B and 9B parameter counts, is designed for consumer hardware and latency-sensitive applications. BFL achieved this speed through model distillation, enabling image generation in just four steps. The architecture unifies text-to-image generation and editing capabilities, supporting features like multi-reference editing and precise hex-code color control.
