Trustworthy AI operations with conversational assistance and agentic workflows

Abstract

The rapid advancement of Artificial Intelligence (AI) capabilities—from static models to autonomous agents—has created a critical "Operations Gap," where the ability to develop powerful models has outpaced the capacity to integrate, monitor, and control them reliably in real-world environments. Traditional operational paradigms like Machine Learning Operations (MLOps) are often insufficient for modern agents that exhibit autonomy, non-determinism, and direct interaction with humans. This thesis addresses this gap by establishing the discipline of Trustworthy AI Operations, providing a roadmap for deploying autonomous AI that is not only powerful but also reliable, transparent, and aligned with human values.A central contribution of this work is a novel taxonomy that characterises the operational maturity of AI systems through five evolving levels: Handcrafted, Integrated, Augmented, Trusted, and Autonomous. Handcrafted systems rely on manual, disjoint implementations with minimal autom ...
