FLUX.1 is a text-to-image model developed by Black Forest Labs, based in Freiburg im Breisgau, Germany. Black Forest Labs was founded by Robin Rombach, Andreas Blattmann, and Patrick Esser.[1]

History

Black Forest Labs was founded in 2024 by former employees of Stability AI. All three founders had previously researched the artificial intelligence image generation at Ludwig Maximillian University of Munich as research assistants under Björn Ommer.[2][3][4] They published their research results on image generation in 2022, which resulted in Stable Diffusion.[4][5] In August 2024, the model was integrated into the Grok chatbot developed by XAI and available as part of premium feature on X (formerly Twitter).[6][7] Investors in Black Forest Labs include Andrerssen Horowitz, Brendan Iribe, Michael Ovitz, Garry Tan, and Vladlen Koltun. The company received an initial investment of US$31 million.[8]

Models

The FLUX.1 model is a series of text-to-image models. The models are based on a hybrid architecture that combines multimodal and parallel diffusion transformer blocks.[9] The models are released free of charge under different licenses with Schnell (Fast in German) released as open-source software under Apache License, Dev released under a non-commercial license, and Pro released as proprietary software and only available as API that can be licensed by third-party users.[10]

Criticism

The model has been criticised for its very realistic generated images. According to media reports, depictions ranged from an image of Donald Trump posing with guns to disturbing scenes, which triggered discussions about ethical implications of technologies developed by Black Forest Labs.[2]

After the release of the model, social media X (formerly Twitter) was flooded with FLUX.1-generated images.[11][12] Black Forest Labs has not provided exact details of the data used to train the model. Ars Technica suspected that FLUX.1 is based on a large, unauthorised collection of images scrapped from the internet, a controversial practice with potential legal consequences.[13][14]
