Banki.ru Unveils YandexGPT-Powered AI Chatbot for Enhanced Financial Assistance

The financial marketplace «Banki.ru» has introduced an AI assistant powered by YandexGPT. This new chatbot assists users in finding financial solutions and answering their inquiries. It is currently active on the website, where it is utilized by over 20 million individuals. By the end of 2025, it is expected that the bot will handle 20% of user interactions.

This assistant is built on the RAG architecture, which searches for documents within an internal knowledge base without transmitting data online. The bot operates alongside the Rasa system, which identifies the purpose of user queries and directs them to either the AI assistant or a human operator.

The technology functions as follows: when a user poses a question in the chat, the Rasa system determines the intent, YandexGPT retrieves information from the database, and then formulates a response. The interface includes widgets for selecting financial products and tracking application statuses.

The project was developed by the «Banki.ru» team in collaboration with Yandex Cloud. The implementation involved testing with internal documents, building a knowledge base, filtering inquiries, and prioritizing system setups.

«Banki.ru» boasts a knowledge base of 135 GB, which grows by 1.5 GB each week, containing over 630,000 text pages. Previously, the search function relied on exact word matches and struggled with synonyms, but now users receive responses in under 1.3 seconds.

The bot is programmed in PHP, while the Q&A service module uses Python. The team has deployed a Yandex Managed Service for Kubernetes cluster for the Docker containers. Data processing from Wiki was facilitated by Apache Airflow.

Currently, the chatbot is undergoing testing in users’ personal accounts. The team plans to roll it out to external users in the «Banki.ru» application under the name «Financial Assistant.» Future developments include implementing a topic classifier to enhance answer accuracy and creating a service for finding AI-generated reviews.
