ChatTCU: Inteligência Artificial como assistente do auditor

Abstract

The Brazilian Federal Court of Accounts (TCU) has adopted artificial intelligence (AI) to optimize its auditing and administrative operations, resulting in the creation of ChatTCU, an advanced tool based on OpenAI’s ChatGPT language model. This innovative effort led to the development of a chatbot that initially replicated ChatGPT functionalities and, with subsequent evolutions, began to incorporate data from TCU’s internal systems. The tool allows users to perform a variety of functions, such as accessing selected jurisprudence, administrative services, and summarizing documents, highlighting TCU’s commitment to modernization and operational efficiency. The command of this AI uses prompt engineering as a method to enhance interaction with large language models (LLMs), enabling more accurate and contextualized responses. The Retrieval-Augmented Generation (RAG) technique is used to integrate specialized knowledge from the institution or directly from the user. The rapid adoption of ChatTCU by TCU units reflects its immediate value and effectiveness in meeting operational needs, while demonstrating a strategic alignment with the institutional goals of promoting innovation and continuous improvement in audit and administrative processes.
