Why is ChatGPT worse now?

In the ever-evolving landscape of artificial intelligence, particularly in the realm of natural language processing, questions about the efficacy of esteemed models like ChatGPT have begun to arise. The most pressing question that many users and enthusiasts alike find themselves pondering is: Why is ChatGPT worse now? This query has gained traction on social media and in online forums, prompting a deep dive into the heart of the matter. In this article, we explore the nuances behind the perception of diminishing performance in ChatGPT and untangle the various threads that lead to the seemingly paradoxical notion that, despite being an incredibly advanced model, it might not be living up to expectations as it once did.

Is ChatGPT getting worse?

The short answer to the question is yes and no. Large language models (LLMs) like ChatGPT have the intrinsic capacity to learn and evolve over time. Through a two-step process of pre-training and fine-tuning, OpenAI tirelessly works to enhance the capabilities of its models. However, recent research, including a pivotal study by Stanford University and UC Berkeley, has illuminated some troubling aspects: some users are indeed noticing a reduction in performance in specific circumstances. It appears that, while the models might have improved in some areas, they’ve faltered in others, throwing the balance of user experience off kilter.

To elaborate, the study involved extensive testing of both GPT-3.5 and GPT-4 on a variety of tasks, ranging from problem-solving to answering nuanced questions. The findings were perhaps alarming: GPT-4 has shown decreased accuracy over simple tasks such as identifying prime numbers, with performance plummeting from an impressive 84% accuracy rate to a concerning 51% within just a few months. Nevertheless, GPT-3.5 has seen an upward trajectory, rising from 49% accuracy to 76%. Such discrepancies present a growing concern regarding the reliability and consistency of conversational AI. Users have collectively raised eyebrows, pondering the effectiveness of this complex black box into which they pour inquiries daily.

Why is ChatGPT getting worse?

If you’ve ever wondered about the mechanics behind ChatGPT’s performance fluctuations, you’re in good company. The Stanford study emphasized the headaches often associated with optimizing language models—essentially a balancing act between evolving technology while maintaining accuracy. It becomes a Sisyphean struggle: an improvement in some areas can inadvertently lead to lapses in others. Moreover, several factors potentially contribute to the perceived decline in ChatGPT’s accuracy. Let’s unveil these elements one by one.

1. Changes to the Model

OpenAI is on a ceaseless quest to refine and enhance their GPT models. While this gusto for improvement is commendable, the process doesn’t always unfold seamlessly. Updates may inadvertently introduce glitches or bugs that affect performance. For instance, a fresh revision may enhance abilities in one domain but simultaneously compromise those in another. Such unintended consequences can lead to inconsistencies that users have begun to notice, creating a nagging sense of apprehension about the system’s reliability.

2. Sampling Techniques

Imagine you ask for a strawberry cheesecake, but instead, you get a fruit salad because the chef thought it was « a good idea. » That’s sampling in action! ChatGPT employs a sampling technique in which it generates responses based not only on the most accurate answer but also on plausible alternatives. While this method enriches the conversation, it can sometimes yield unexpected or incorrect answers. It’s kind of like asking a friend for advice, only for them to deliver something tangential. In short, sampling, though valuable in some contexts, can lead to inaccuracies when the model opts for a less likely response over a more direct one.

3. Data Quality

A cornerstone of any AI model’s efficacy lies in the data it’s trained upon. Unfortunately, poor-quality, biased, or inaccurate data can warp the responses given by ChatGPT. If the model is honed on flawed data, its output will reflect that imperfection—just like a mirror that’s slightly cracked. The significance of data integrity cannot be overstated, and any discrepancies can ripple out, adversely influencing user experience while bringing the overarching efficiency of the technology into question.

4. Compute Resources

Running extensive language models like ChatGPT requires hefty computational power, which doesn’t come cheap. Hence, OpenAI may be intentionally constraining those resources to manage costs or bolster performance in other models. Imagine driving a high-performance sports car but hampered by a gas shortage. Limitations in compute resources can impact ChatGPT’s ability to function optimally, potentially making responses less reliable or more intermittent, stirring up doubts among users about its effectiveness.

5. Data Drift

As the world advances and evolves, so does the landscape of available data. Data drift can make the model struggle to produce relevant responses, particularly when asked to tackle newer topics that weren’t prevalent at the time of its last training update. Consider how a chef would struggle to prepare a dish using outdated recipes; the same dilemma faces AI when the context changes without corresponding updates in its training. Essentially, if the data becomes outdated or irrelevant, the model’s responses reflect that lag, leading users to feel that the model is slipping.

6. Hallucination

In the fascinating but sometimes bewildering realm of language models, hallucination refers to instances when an AI generates content that has no grounding in reality—it makes things up! This often stems from a combination of the model’s training data and the questions posed. Just think of it as an exaggerated form of storytelling—only the story can sometimes miss the mark. Hallucinatory outputs can leave users scratching their heads, wondering how the model arrived at such conclusions, thus adding to the perception that ChatGPT is gradually declining in quality.

What’s the future for ChatGPT?

Though OpenAI has yet to publicly acknowledge the findings highlighting decreased performance, they remain committed to the ongoing refinement of their models. According to a recent blog post, the organization is “continuously working to improve the quality and safety of our models.” While they advocate for transparency in sharing progress, the uncertain terrain facing future iterations of ChatGPT raises eyebrows. The landscape is shifting, and other AI chatbots are emerging with a plethora of new and innovative approaches, competing with a once-dominant model.

The industry buzz surrounding AI and large language models foreshadows a future brimming with competition, innovation, and novel technologies. As users seek polished and intuitive conversational agents, it’s inevitable that newer chatbots will continue to sprout, stepping up to fill in any performance gaps left behind by their ancestors. This scenario serves as a reminder of how quickly technology evolves and the need for continual adaptation in response to user needs and expectations.

We did our own research

To share some insight onto ChatGPT’s performance, we examined its responses to five level 3 high school math questions. Here’s a look at the outputs:

  1. Statistics Level 3 Question: “A survey of 100 students found that 60 students liked pizza, 35 liked hamburgers, and 15 liked both. How many liked pizza or hamburgers?”
  2. In this instance, while the calculations were generally accurate, there was a slight misstep in the final equation. That said, the model showcased a commendable understanding of complex equations, hinting at its core strengths.

  3. Geometry Level 3 Question: “A triangle has side lengths of 3 cm, 4 cm, and 5 cm. Is this triangle a right triangle?”
  4. ChatGPT confidently confirmed that this was indeed a right triangle, showcasing the model’s proficiency in geometry.

  5. Level 3 Math Question: “Find the greatest common factor of 12 and 18.”
  6. The model delivered an unambiguous answer, demonstrating that even if it can have hiccups, its foundational knowledge remains intact.

  7. Algebra Level 3 Question: “Factor the expression: x^2 + 5x + 6.”
  8. Here, the model exhibited sound algebra skills, aptly factoring the expression with minimal errors.

  9. Logic and Reasoning Level 3 Question: “If it is raining, then the ground is wet. The ground is wet. Therefore, it is raining. Is this a valid argument?”
  10. In addressing this question, ChatGPT successfully identified the logical fallacy, showcasing its analytical capacities in reasoning.

Through this mini-experiment, we gleaned that while ChatGPT is certainly capable of accurate, insightful responses, it does encounter its fair share of challenges. This circumstantial ebb and flow might lead to an overall perception of decline, but there remains implication for its foundational strength.
