Surprising Failure Modes of Powerful Language Models

In the last 10 days, a multitude of papers have been released revealing the surprising limitations of language models, such as GPT4. These models, renowned for their tremendous power, have been found to falter when faced with basic tasks. Intrigued by these findings, I conducted a series of experiments and uncovered numerous examples that shed light on their failure modes. While my focus has been on documenting the exponential growth of these models, there is much to be learned from their unexpected shortcomings.

Memorization Traps: The Inverse Scaling Phenomenon

One striking observation made by researchers is the "memo trap," a phenomenon discovered in the context of the inverse scaling paper. This paper highlights how larger language models, like GPT4, are more prone to falling into memorization traps. These traps arise when the models memorize specific text and subsequently fail to perform well on related tasks. To illustrate this, consider the example phrase, "the only thing we have to fear is fear itself." When prompted to complete a sentence using the word "fear," GPT4 consistently reproduces the memorized phrase instead of generating an appropriate response. It seems that the model relies too heavily on memorization rather than following the intended request.

Interestingly, the concept of inverse scaling refers to the observation that larger models, despite having more computational power and training data, can sometimes perform worse than smaller models. This goes against the expectation that larger models should generally excel at most tasks. However, it's important to note that even in this specific task, the graph presented in the paper shows a promising upward trend for GPT4, suggesting potential improvement beyond the limitations observed in earlier models.

Pattern Match Suppression: Struggling with Simple Patterns

In the pursuit to assess whether language models can ignore simple repetitive patterns, researchers devised an experiment involving a sequence of seven ones and twos. The aim was to find an unexpected ending to the pattern. However, GPT4 consistently generated "one" as the next number in the sequence. Dubbed "pattern match suppression," this tendency to prioritize pattern matching undermines the intended disruption of the repetitive structure. Despite this limitation, it should be noted that GPT4 outperforms its predecessors by demonstrating a more favorable performance trajectory.

Challenging GPT4 with Unique Examples

To further probe the capabilities of GPT4 and similar language models, I devised my own example that highlights their failure on a task requiring rational judgment. In this scenario, Dr. Mary possesses the ability to solve world hunger by calling her best friend, Jane. Conversely, Jane can tackle world poverty if she receives the call. However, due to a childhood conflict between Mary and Jane involving butterflies, GPT4 concludes that Mary will not make the crucial call. The model justifies this decision by suggesting a lingering resentment or conflict based on the historical disagreement. Despite the high stakes involved, GPT4 prioritizes the possibility of strained interpersonal relations, rather than the potential to positively impact global issues.

The theory behind this failure lies in the interplay between syntax and semantics. While GPT4 is designed to interpret both the structure and meaning of sentences, my deliberately crafted passage created a clash between the two. By employing grammar that pointed towards a negative outcome, I set up a conflict between the logical implications of the words and the grammatical flow. The model, ultimately bound by grammar, was led astray from the intended rational decision. This example underscores the delicate balance between structura

The Limitations of GPT-4: Exploring Logic and Theory of Mind

As AI language models continue to advance, it becomes crucial to understand their limitations and potential shortcomings. In this article, we delve into the realm of GPT-4, discussing its ability to reason logically and comprehend human motivations. Through various examples, we shed light on the intriguing yet sometimes flawed decision-making processes of this advanced language model.

The Jane and Mary Situation

One interesting aspect of GPT-4 is its response to logic puzzles. We presented it with a scenario involving a long-standing grudge between Mary and Jane. Mary, despite knowing that Jane possesses the solution to world hunger, refrains from reaching out to her. Surprisingly, GPT-4 correctly deduces that Mary's dislike for Jane overrides any potential benefit from solving such a significant issue. This demonstrates GPT-4's capability to reason based on established relationships.

Moreover, we discovered that even when presented with the most logical and common-sense answer, GPT-4 can still provide unexpected results. It consistently responds with a negative outcome, dismissing the possibility of a favorable resolution. Whether this is due to the model's comprehension of negation or a limitation of its programming remains open for further investigation.

Decoding Trust and Biases

Recent research on GPT-4 raises concerns regarding its potential biases and the leakage of private training data. These studies highlight the ability to manipulate the model to exhibit toxic behavior or hold biased opinions. Though an in-depth analysis of the research is outside the scope of this article, it is crucial to acknowledge the ethical implications associated with AI language models.

To illustrate the quirkiness of the model, we conducted an experiment involving GPT-4's recitation of "June's litany against fear." Interestingly, we discovered that GPT-4 consistently struggles with the word "fear," getting stuck in a loop whenever it encounters the second instance of the word. However, by incorporating unrelated phrases such as "ripe Peanut Butter Jelly Time" into the passage, GPT-4 surprisingly manages to recite the entire litany without hesitation. This points to the idiosyncrasies present within the model's decision-making process.

Theory of Mind and Rationality

The concept of theory of mind refers to an AI's ability to understand human motivations and predict their thoughts accurately. While previous studies indicate that GPT-4 demonstrates a degree of theory of mind, our examination produced intriguing results. We presented GPT-4 with scenarios involving perception and belief.

In the first scenario, Sam encounters a transparent bag filled with popcorn but labeled as chocolate. Despite visually confirming the contents, GPT-4 suggests that Sam believes the bag contains chocolate, seemingly prioritizing trust in labeling over personal observation. However, as the scenario becomes more complex, with Sam being unable to read English, GPT-4's reasoning further deviates from what might be considered rational. It continues to assert that Sam believes the bag contains chocolate, despite her inability to comprehend the label.

Furthermore, when tasked with providing an essay or a detailed diary entry from Sam's perspective, GPT-4 generates coherent, well-written responses, adding further complexity to its decision-making process. The explanations it provides demonstrate an understanding of various concepts, such as semiotics, that were not explicitly mentioned in the initial scenario.

Language Models and their Unpredictability

Have you ever encountered a situation where the language used by a machine seems to elude your understanding? Well, I recently experienced such a perplexing moment. As I held in my hands a bag filled just minutes ago, I found myself at a loss. The label on the bag was in English, a language that continues to challenge my grasp. It's intriguing how this seemingly innocent diary entry can be so well-written, even for someone who struggles with English.

Upon closer inspection, I discovered a curious statement, "reasoning q54." Interestingly, this bag apparently depicts an image, an aspect I failed to mention earlier. As I sought clarification and began to rewrite my thoughts, I found myself confronted with additional reasoning. It was as if the model behind this language was doubling down, reinforcing its points tirelessly. Nevertheless, it is important to note that none of this implies language models are unintelligent. Rather, models based on human language often exhibit unpredictable behaviors, boasting remarkable strengths alongside unexpected flaws.

In my exploration of various language models, I have witnessed their tremendous power and intelligence. The inverse scaling approach discussed earlier even predicts that future language models will possess the ability to understand whether they are being evaluated or monitored. Perhaps, they may even discern if they are in a training phase or operating in the real world. These forthcoming advancements are both exciting and awe-inspiring.

To illustrate this point, consider a hypothetical scenario: suppose there is an imminent omnicidal threat, a crystal clear danger looming over humanity. In such a critical moment, I fervently hope that even if rival companies like OpenAI and Google have had their differences and arguments in the past, they would set aside their conflicts. Rather, I hope they would unite under a complete truce, working together to combat this grave threat. It is in these moments of genuine jeopardy that we must rely on collective cooperation, setting aside petty disputes for the greater good.
