The rapid evolution of large language models (LLMs) like ChatGPT has necessitated a reevaluation of AI governance models due to their ability to generate human-like text across diverse topics, presenting both opportunities and challenges. While traditional machine learning governance focused on narrow AI systems with specific tasks and clear risk management frameworks, LLMs require more complex governance due to their open-ended nature and the potential for misuse, such as spreading misinformation. Organizations must develop policies that guide the appropriate use of LLMs, emphasize workflows over architecture, and implement dynamic risk management frameworks. Effective governance should involve bespoke integration solutions, advanced operations tools for real-time monitoring, and transparent auditing methodologies to ensure accountability. By addressing these challenges, organizations can responsibly harness the capabilities of LLMs while managing potential risks, promoting innovation, and ensuring ethical deployment.
