Key Features

Open-weight architecture

Model weights are publicly available to promote transparency, research, and community-driven improvements.

Guidance distillation from FLUX [pro]

Direct distillation from the FLUX [pro] model to deliver high visual quality and better inference efficiency.

Exceptional prompt adherence

Advanced prompt-following capabilities allow nuanced and precise control over generated images.

Support for diverse aspect ratios and resolutions

Built-in flexibility to generate images across a wide range of aspect ratios and output resolutions for different use cases.

Enhanced typography rendering

Improved text and typography handling for outputs that include legible words and signage.

Improved anatomical accuracy

Better rendering of human features (notably hands and proportions) relative to many prior open-source models.

Improved output diversity

Mechanisms to produce a broader range of stylistic and compositional variations.

Hybrid architecture & modern techniques

Combines multimodal diffusion transformer blocks with techniques such as flow matching and rotary positional embeddings for coherent, high-quality outputs.
