В данной статье рассматриваются ограничения традиционных моделей машинного обучения при работе с дефицитом данных и развивающимися схемами мошенничества в финансах. Мы предлагаем новую гибридную архитектуру, которая интегрирует генеративно-состязательные сети (Generative Adversarial Networks, GAN), большие языковые модели (Large Language Models, LLM) и вариационные автоэнкодеры (Variational Autoencoders, VAE) для улучшения кредитного скоринга, обнаружения мошенничества и автоматизации финансовых документов. Наш метод использует условную табличную GAN (Conditional Tabular GAN, CTGAN) для генерации синтетических данных и балансировки наборов данных, VAE для обнаружения аномалий в транзакционных данных и LLM для формирования интерпретируемых отчетов и документов соответствия. Экспериментальные результаты показывают, что модели, обученные на данных, дополненных с помощью GAN, достигают увеличения AUC на 8% для кредитного скоринга и улучшения F1-меры на 18% для обнаружения мошенничества на несбалансированных наборах данных. Специальный слой соответствия снизил демографическое смещение на 37%. Исследование подтверждает, что тщательно разработанная система генеративного ИИ может значительно повысить производительность моделей, их справедливость и операционную эффективность в приложениях FinTech, одновременно решая критически важные этические и регуляторные задачи.</p></abstract><trans-abstract xml:lang="en"><p>Generative Artificial Intelligence (AI) transforms financial technology (FinTech) by creating synthetic data, enhancing predictive analytics, and automating complex tasks. This paper addresses the limitations of traditional machine learning models in handling data scarcity and evolving fraud patterns in finance. We propose a novel hybrid framework that integrates Generative Adversarial Networks (GANs), Large Language Models (LLMs), and Variational Autoencoders (VAEs) to improve credit scoring, fraud detection, and financial document automation. Our method employs a Conditional Tabular GAN (CTGAN) for synthetic data generation to balance datasets, a VAE for anomaly detection in transactional data, and an LLM for generating interpretable reports and compliance documentation. Experimental results demonstrate that models trained on GAN-augmented data achieve an 8% increase in AUC for credit scoring and an 18% improvement in F1-score for fraud detection on imbalanced datasets. A dedicated compliance layer reduced demographic bias by 37%. The study confirms that a carefully designed generative AI framework can significantly enhance model performance, fairness, and operational efficiency in FinTech applications while addressing critical ethical and regulatory challenges.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>генеративный ИИ</kwd><kwd>финтех</kwd><kwd>синтетические финансовые данные</kwd><kwd>моделирование кредитного риска</kwd><kwd>обнаружение мошенничества</kwd><kwd>большие языковые модели (LLM)</kwd><kwd>генеративно-состязательные сети (GAN)</kwd><kwd>вариационные автоэнкодеры (VAE)</kwd><kwd>автоматизация финансовых документов</kwd><kwd>соответствие регуляторным требованиям</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Generative AI</kwd><kwd>Fintech</kwd><kwd>Synthetic Financial Data</kwd><kwd>Credit Risk Modeling</kwd><kwd>Fraud Detection</kwd><kwd>Large Language Models (LLMs)</kwd><kwd>Generative Adversarial Networks (GANs)</kwd><kwd>Variational Autoencoders (VAE)</kwd><kwd>Financial Document Automation</kwd><kwd>Regulatory Compliance</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Goodfellow, I., Pouget-Abadie, J., Mirza, M., Xu, B., Warde-Farley, D., Ozair, S., Courville, A., and Bengio, Y.
