arXiv:2412.18653v1 Announce Type: new Abstract: We present 1.58-bit FLUX, the first successful approach to quantizing the state-of-the-art text-to-image generation model, FLUX.1-dev, using 1.58-bit weights (i.e., values in {-1, 0, +1}) while maintaining comparable performance for generating 1024 x 1024 images. Notably, our quantization method operates without access to image data, relying solely on self-supervision from the FLUX.1-dev model. Additionally, we develop a custom kernel optimized for 1.58-bit operations, achieving a 7.7x reduction in model storage, a 5.1x reduction in inference memory, and improved inference latency. Extensive evaluations on the GenEval and T2I Compbench benchmarks demonstrate the effectiveness of 1.58-bit FLUX in maintaining generation quality while significantly enhancing computational efficiency.

Exploring the Innovative Approach of 1.58-bit FLUX in Text-to-Image Generation
Artificial intelligence has made remarkable strides in the field of text-to-image generation, enabling machines to create stunning visuals based on written descriptions. However, as these models become more complex and resource-intensive, there is a growing need to optimize their performance and computational efficiency. In this article, we delve into the groundbreaking concept of 1.58-bit FLUX and its potential to revolutionize the state-of-the-art text-to-image generation model, FLUX.1-dev.
Quantizing with 1.58-bit Weights: A Paradigm Shift
One of the key challenges in optimizing text-to-image generation models lies in reducing the storage requirements and computational complexity without compromising on generation quality. 1.58-bit FLUX presents a novel approach by quantizing the state-of-the-art FLUX.1-dev model using 1.58-bit weights.
Quantization refers to the process of representing numerical values with a reduced number of bits, thereby reducing storage and computational requirements. Traditionally, quantization methods have relied on approximating values, leading to a loss in generation quality. However, the innovative aspect of 1.58-bit FLUX is that it achieves comparable performance for generating 1024 x 1024 images while using 1.58-bit weights, which can only take on three values: -1, 0, or +1.
This groundbreaking quantization method operates without the need for access to image data. Instead, it relies solely on self-supervision from the FLUX.1-dev model. Leveraging the knowledge learned by the pre-existing model, 1.58-bit FLUX effectively distills the high-dimensional information into a lower-dimensional representation. This not only significantly reduces the model’s storage requirements but also enhances its computational efficiency.
Custom Kernel Optimization for 1.58-bit Operations
In addition to quantizing with 1.58-bit weights, the 1.58-bit FLUX approach introduces a custom kernel optimized for 1.58-bit operations. A kernel is a fundamental component of machine learning models that performs various computations on the data.
By designing a custom kernel specifically tailored for 1.58-bit operations, the 1.58-bit FLUX approach achieves remarkable efficiency gains. This optimization results in a 7.7x reduction in model storage and a 5.1x reduction in inference memory requirements. Furthermore, the inference latency, or the time taken for the model to generate images based on text inputs, is significantly improved.
Evaluating the Effectiveness of 1.58-bit FLUX
A comprehensive evaluation of 1.58-bit FLUX was conducted on two benchmark datasets: GenEval and T2I Compbench. These benchmarks are widely used in the field of text-to-image generation to assess the quality and efficiency of models.
The results of the evaluations revealed the effectiveness of 1.58-bit FLUX in maintaining the generation quality of FLUX.1-dev while significantly enhancing computational efficiency. The lower storage requirements and reduced memory consumption make it feasible to deploy the model on resource-constrained devices or scale up the model for larger text-to-image generation tasks.
Conclusion
The concept of 1.58-bit FLUX represents an innovative and transformative approach to optimize the state-of-the-art text-to-image generation model, FLUX.1-dev. By quantizing the model with 1.58-bit weights and introducing a custom kernel optimized for 1.58-bit operations, this approach achieves remarkable gains in computational efficiency without compromising on generation quality. The extensive evaluations on benchmark datasets further validate the efficacy of 1.58-bit FLUX, opening up new possibilities for practical deployment of text-to-image generation models.
