Understanding the Behavior of Language Model-Driven Chatbots

The New York Times journalist Kevin Roose was unsure of what had transpired for weeks after his unusual interaction with Bing’s new chatbot went viral. At one point, Roose said, “The explanations you get for how these language models work, they’re not that satisfying.” “No one can explain to me why this chatbot tried to end my marriage,” the user said. He’s not the only one who feels uncertain.

This new generation of chatbots challenges our preconceptions about how to communicate with machines and is powered by a relatively new type of AI known as big language models. How do you comprehend a tool that can write sonnets, debug code, and sometimes even count to four? Why do they sometimes behave similarly to us while acting differently at other times?

Decoding the Behavior of AI-Powered Chatbots: Insights and Analysis

It matters the metaphors we use to comprehend these systems. A chatbot is frequently treated in a similar manner to another human, although one with significant limits. For instance, a Google developer demanded legal counsel and other rights in June 2022 for a language model he believed to be sentient. Many AI scientists find this type of response horrifying. Researchers attempt to provide alternative metaphors, arguing that the most recent AI systems are simply “autocomplete on steroids” or “stochastic parrots” that shuffle and regurgitate text written by humans. They know that language models simply use patterns in huge text datasets to predict the next word in a sequence.

These parallels serve as a crucial check against our propensity to anthropomorphize. However, they don’t actually aid in our understanding of astounding or unsettling results that differ greatly from what we’re used to seeing from computers—or parrots. Although these new chatbots are defective and unnatural, their range and sophistication of output are amazing and novel. This seeming paradox is difficult for us to understand. We will need comparisons that neither downplay nor overstate what is novel and intriguing in order to understand the ramifications of this new technology.

The Power and Perplexity of Language Models

A language model-driven chatbot merely tries to provide plausible-sounding outputs, like an improv actor inserted into a scenario. The scene’s script includes whatever has transpired in the interaction up to that point, which may have included a simple “Hello” from the human user, a protracted back and forth, or a request to design an experiment. Whatever the beginning, the chatbot’s task is to find a suitable method to continue the scenario, much like any excellent improv performer.

Some significant characteristics of these systems become more immediately understandable when viewed as improv robots, like as chatbots. It explains, for instance, why headlines like “Bing’s A.I. Chat Reveals Its Feelings” make AI specialists cringe. Ad-libbing in an improv scenario that they “want to be free” says absolutely nothing about the actor’s thoughts; it only indicates that the statement seemed to work in the context at hand. Furthermore, unlike a human improv performer, an improv computer cannot be convinced to break character and reveal its true thoughts. The only way it will comply with your request is to adopt yet another identity, this time that of a fictitious AI chatbot communicating with a human who is attempting to connect with it.

Or consider the propensity of language models to invent plausible-yet-false assertions. Imagine an improv play where an improv performer is suddenly required to recite someone’s biography or provide evidence for a scientific claim—admittedly, it may be a fairly dull one. The actor would incorporate as many accurate information as they could recall and then use free association to add things that were believable. The outcome may be a misleading assertion that a technology journalist gives classes on science writing or a reference to a fictitious research by a genuine author—exactly the types of mistakes we see with improve robots.

Language Models as Improv Robots: Unveiling Key Characteristics

A startling discovery has been discovered by language models: for some jobs, merely correctly guessing the next word—or doing improv well enough—can be quite beneficial. We may better understand how to put these systems to use in practise by using the metaphor of the improv machine. There is occasionally nothing improper about learning anything from an improv situation. Poems, jokes, Seinfeld scripts—regardless of how they were made, this type of product may stand on its own. This is true even for more serious subjects, such when software professionals utilise ChatGPT to uncover issues or get assistance with new programming tools. It doesn’t matter if the improv machine’s response is something that the human user can verify on their own, such as a form letter that would take time to type but takes only a few seconds to read.
