Generative artificial intelligence (GAI) started making waves a few years ago with the release of systems such as ChatGPT and DALL-E. They are able to produce sophisticated and human-like text, code, or images after the models powering them are trained on large quantities of data. However, it soon became apparent that the specific phrasing of a question or statement input by a user, known as a prompt, had an impact on the quality of the resulting output.

Several years ago, I compiled the first reference book on AI policies.1 I aimed to provide a ready reference for the emerging field of artificial intelligence similar to the books I had published on privacy law.2  At that time, we noted the rapid explosion of AI ethics frameworks, but it was still early days for AI governance. The OECD had just finalized the first AI principles endorsed by national governments.

It has become abundantly clear that some people use large language models (LLMs) for nefarious purposes. These artificial intelligence (AI) systems can write convincing spam, generate false news and information, spread propaganda, and even produce dangerous software code. Yet these concerns, while deeply troubling, primarily reflect human prompting techniques rather than any attempt to tamper with the model.

Artificial intelligence (AI) captured the world’s attention in 2023 with the emergence of pre-trained models such as GPT, on which the conversational AI system ChatGPT is based. For the first time, we can converse with an entity, however imperfectly, about anything, as we do with other humans. This new capability provided by pre-trained models has created a paradigm shift in AI, transforming it from an application to a general-purpose technology that is configurable to specific uses.

Deep fake videos have become so convincing that we now depend on human fact checkers to flag them for us (for instance, this Kari Lake deep fake). Contemporary researchers have also recently uncovered the fact that voice alone can be subtly manipulated to persuade people to adopt favored opinions using vocal cues including pitch shifting, tempo adjustments, stereotypical phonation, speech-pattern alterations, and vowel-enunciation alterations.
