FLUX.1 Architecture | Demystifying FLUX.1

FLUX.1 1 is a Rectified-Flow transformer trained in the latent space of an image encoder, introduced by Black Forest Labs in August 2024. The FLUX.1 models demonstrate State-of-the-art (SoTA) performance for text-to-image tasks, in both terms of output quality and image-text alignment, as demonstrated in Figures 1 and 2 using the ELO-score metric, which ranks image generation models based on human preferences in head-to-head comparisons. Figure 1. FLUX.1 defines a new state-of-the-art in image detail, prompt adherence, style diversity and scene complexity for text-to-image synthesis. Evaluation from 2 Figure 2 ELO scores for different aspects: Prompt Following, Size/Aspect Variability, Typography, Output Diversity, Visual Quality. Evaluation from 2 While the model adheres to the Rectified Flow training paradigm (according to the developers statement), the exact details regarding the training setup —including the dataset, scheduling strategy, and hyperparameters— have not been publicl
