A team of scientists at HSE FCS and Yandex Research has proposed a method that reduces computational costs and accelerates text-to-image generation in diffusion models without compromising quality. These models currently set the standard for text-to-image generation, but their use is limited by high computational loads, the company said in a statement.

It is further specified that the developed method—Scale-wise Distillation of Diffusion Models (SwD)—avoids redundant computations during image generation, allowing results to be produced in just 0.3–0.4 seconds.

According to one of the authors, the generation process in diffusion models typically requires dozens of steps involving high-resolution computations. However, in the early stages, only the general structure of the image is formed, and fine details are not yet distinguishable; as a result, some of these computations are redundant. The proposed SwD framework addresses this problem in two ways. First, generation begins at a low resolution and is progressively refined as noise is reduced, eliminating redundant computations in the early stages. Second, the method uses distillation of pre-trained models such as FLUX and Stable Diffusion 3.5, whereby a simpler student model learns to replicate the output of a more complex one, reducing the number of generation steps from dozens to just 4–6. 

The authors propose a new loss function for training—Maximum Mean Discrepancy (MMD), which compares how the teacher model 'sees' an image at its internal processing levels with how the student model represents the same image. Unlike traditional approaches, this method does not require auxiliary models, simplifying and accelerating training, the company emphasises. Moreover, MMD can be used as a standalone distillation (knowledge compression) technique: in experiments, the time per training iteration was reduced sevenfold compared to more complex combined approaches. 

The new approach reduces generation time from several seconds to just 0.3–0.4 seconds while maintaining visual quality. As a result, SwD makes modern diffusion models faster and more cost-efficient to use, improving their accessibility for practical applications, the company statement says.

The solution is described in a paper to be presented at ICLR 2026, one of the leading conferences on artificial intelligence.

Physicists at HSE University and FIAN Discover Way to 'Photograph' Sound for Testing Materials Used in 6G Communications

Researchers at HSE University, in collaboration with colleagues from the Lebedev Physical Institute of the Russian Academy of Sciences (FIAN), have developed a method for rapidly determining how firmly a film is bonded to a substrate. This is important for the creation of ultrahigh-frequency acoustic filters, which are key components of next-generation 5G and 6G communications. For the first time, researchers have succeeded in measuring the lateral rigidity of the bond between a two-dimensional material film and a substrate in this way. The study results have been published in Applied Physics Letters.

In June 2026, the HSE Faculty of Computer Science (FCS) completed a course on the use of artificial intelligence in medicine for first-year Paediatrics students at the Russian University of Medicine. The course was delivered with support from a grant awarded to HSE University under the Artificial Intelligence federal project, part of the national project ‘Data Economy and the Digital Transformation of the State.’

A team of Russian researchers, including scientists from HSE University–St Petersburg, has developed the first open multimodal dataset containing recordings of brain activity, heart function, and video observations to help researchers understand what happens in the human brain during deep concentration. In the future, the dataset could accelerate the development of neural interfaces, rehabilitation technologies, and AI systems. The article has been published in Scientific Data.

HSE University is preparing to launch its second supercomputer. The new cluster will be primarily dedicated to artificial intelligence (AI) workloads and will complement the existing cHARISMa supercomputer. It is scheduled to become operational by the end of 2026.

Team Success: Aligning Means with Objectives

In corporations, sports, and academia, people often face challenges they cannot handle alone. In such cases, selecting the right team is crucial. Tatiana Mayskaya, Associate Professor at the HSE Faculty of Economic Sciences and the International College of Economics and Finance, together with colleagues from foreign universities, examined team characteristics and found that less diverse teams are better suited to objectives where a high average performance is important, whereas more diverse teams are preferable when avoiding failure is critical. The paper has been published in Economic Theory.

The devices, created by student teams, will conduct space research on the properties of promising solar cells, on-board energy storage systems, and serial electronics for student satellites.

Economists Propose More Effective Approach to Reducing Smoking

Economists at HSE University have examined how smokers respond to changes in cigarette prices. When tobacco prices increase, cigarette consumption does not always decline. In fact, spending on tobacco may even rise: according to the researchers, a 1% decrease in cigarette affordability leads to a 0.28% increase in per capita tobacco expenditure. The findings suggest that to reduce smoking rates, tobacco prices must rise faster than household incomes. The study has been published in Voprosy Statistiki.

Biologists Discover Unique Properties of MiR-93-5p MicroRNA in Prostate Cancer

Researchers at the International Laboratory of Microphysiological Systems of the HSE Faculty of Biology and Biotechnology investigated how different isoforms of the same microRNA influence gene function in prostate adenocarcinoma. The study found that in some cases, microRNAs can reinforce each other’s effects by targeting and suppressing the same genes. This finding offers a fresh perspective on the molecular mechanisms underlying tumour development and on the search for disease biomarkers. The results have been published in PeerJ.

HSE Researchers Provide the World’s First Legal Definition of a Digital Ecosystem

Digital ecosystems have evolved from a technological innovation into a fundamental institution of the modern economy over the past few years. According to HSE University’s latest estimates, they account for 8.5% of Russia’s GDP. Previously, no jurisdiction had a statutory definition of what constitutes a digital ecosystem. HSE University researchers have addressed this gap by proposing the first legal concept of a digital ecosystem. Their article, ‘The Digital Ecosystem as a Novel Economic Phenomenon and Legal Concept,’ has been published in the BRICS Law Journal.
