Management and Performance Program Chatbot: A Use Case of Large Language Model in the Federal Public Sector in Brazil
Bibliographic record
Abstract
Governments are facing the benefits and perils of recent developments in artificial intelligence. One key objective is using AI to enhance the efficiency and effectiveness of their public service provision. While academic research has examined these advances, there is a lack of empirical evidence regarding user experiences. This paper explores the initial results of using a chatbot based on a Large Language Model (LLM) to address user queries about the Management and Performance Program (PGD). Survey analysis demonstrated that ChatPGD is likely to reduce program-related response time and increase effectiveness. However, the initial tests indicated a need to refine response algorithms to detect and mitigate potential biases and to strengthen the system infrastructure to support new enhancements. This paper examines the chatbot's application in harnessing government databases, highlighting the potential benefits, challenges, and perspectives of embedding AI and LLMs in public service delivery. The insights can support the development of other public service LLMs.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
