Or that your shopping app knows it's time to remind you about the upcoming Diwali festival and suggest relevant products based on your purchases over the past year. This is the depth of personalization that modern recommender systems strive for. Yandex introduces an innovative solution in this field—the ARGUS method for training billion-parameter transformers....

....and is sharing its research methodology with the global technical community. ARGUS (AutoRegressive Generative User Sequential modeling) is a novel, AI-powered architecture that enhances recommender systems by leveraging transformers—similar to those powering large language models (LLMs). The research paper describing this approach was recently published on arXiv, making Yandex one of the few....

Addressing industry challenges Recommender systems face persistent challenges, including limited ability to process long-term user histories, scalability issues, and struggles with evolving user preferences. Traditional systems often ....

....rely on truncated interaction data, missing nuanced behavioral patterns, and lack the flexibility to adapt to dynamic user needs or seasonal trends. These limitations result in less relevant recommendations, reduced user engagement, and the lack of opportunities for discovery. The recommender transformers trained with ARGUS analyze a significantly longer history of user interactions — several ....

These algorithms better detect how user needs evolve over time and account for seasonal patterns. For instance, if a user consistently buys tennis balls from the same brand every summer, the system will proactively remind them when the season approaches. “In recent years, the quality of rec....

We developed a neural architecture that is more efficient in training and requires fewer resources, proving that the leap in quality seen in language models is achievable in recommendations. Only a handful of companies worldwide — such as Yand....
