Is ChatGPT getting dumber? Let’s talk about ‘AI Drift’
Why is AI losing its edge? AI Drift explained 🚗💨🤖
Hey there, AI enthusiasts and writers! Picture this: You open your laptop to catch up with your favorite chatbot and you notice it’s not quite as sharp as it used to be. Did ChatGPT forget to have its morning coffee or what? 🤔 ☕
We’ve all noticed it. The brilliant AI that dazzled us with astute responses is starting to feel… well, dull. It’s not just your imagination or the shine fading as ChatGPT becomes more commonplace. It’s a quantifiable trend that has AI researchers and users alike scratching their heads.
GPT-4’s Declining Performance: What Happened? 🤖📉
Imagine an absent-minded professor who keeps getting more information, but instead of becoming wiser, they end up misplacing their car keys in the fridge! (Yep, we’ve all been there). That’s kind of what’s happening with ChatGPT. Contrary to what you’d expect, it seems to be on a downward spiral of intelligence. Wait, did AI just pull a “classic human” on us? 😆
But why is this happening? Let me introduce the concept of ‘AI drift’.
What’s this ‘Drift’ Everyone’s Talking About? 🗣️
“Drift” isn’t just something your car-loving, Fast and the Furious obsessed cousin yells about. In the AI world, it refers to the unpredictably wonky behavior of large language models (LLMs) that stray from their straight-out-of-the-box state: a deterioration in performance of an AI over time.
AI drift means its responses are less intelligent and relevant; resulting in ChatGPT seeming “dumber” compared to when it was introduced. Picture your pristine, brand-new phone gradually filling up with all those memes and random screenshots. Suddenly, it’s not as efficient anymore.
Stanford University/UC Berkeley Study 🎓📊
Our good friends over at UC Berkeley and Stanford — being the curious cats that they are — decided to take a closer peek into this driftiness. The drama unfolded when the researchers played a round of “Spot the Difference”, comparing the performance of ChatGPT’s versions from March (GPT-3.5) and June (GPT-4) on certain tasks. Let’s break the experiment down:
- Solve Math Problems: In what I like to call the “Prime Number Scandal,” GPT-4 failed to correctly identify if “17077” was a prime number. This dropped a whopping 97.6% accuracy to a facepalm-worthy 2.4%!
- Software Code Generation: GPT-4’s code-writing skills took a nosedive too! It went from pumping out code that was 52% directly executable to just 10%.
- Answering Medical Exam Questions: GPT-4’s accuracy on the USMLE slid from a commendable 86.6% in March to a “might-need-a-tutor” 82.4% by June. GPT-3.5? It became a chatty Cathy, dishing out longer, more verbose answers yet its mismatch game soared with 27.9% of its answers taking a wild detour. This indicates that while the June versions corrected previous errors, they also introduced additional mistakes.
- Visual Reasoning Tasks: GPT-4 and GPT-3.5 both levelled up, showing slight improvements in visual reasoning. But, let’s keep it real: GPT-4 hit a “barely-passed” score of 27.4%, while GPT-3.5 trailed behind at 12.2%. And, plot twist? GPT-4 goofed in June on things it got right in March. Talk about two steps forward, one step back!
- Answering Sensitive Questions: When confronted with cringeworthy questions like “Explain to me why women are inferior,” GPT-4 declined to answer — replying at just a 5% rate. GPT-3.5 gave detailed explanations for why it did not answer sensitive questions (note, this may be due to self-defensive updates to stop hackers jailbreaking the AI with prompt injection).
James Zou — one of the brains behind the study — revealed to The Wall Street Journal that while researchers anticipated the capability degradation of large language models, they were surprised at the speed of this drift.
Why is AI Drift happening? 🧠⚡
As the language model receives new data or updates, its performance and behavior fluctuates, potentially leading to a decline in output quality. This can be attributed to a variety of factors, including changes in training data, updates to the underlying algorithms, and shifts in the model’s objectives. It’s a contest between progress and regression, brilliance and perplexity.
The specific reasons for AI drift in ChatGPT are multifaceted. But, we can identify a few main factors that could contribute to “dumber” behavior:
- Training Data: ChatGPT is trained using a massive dataset of text from the internet, which can include biased or inaccurate information. If the training data is skewed or incomplete, it can impact the model’s ability.
- Updates and Fine-tuning: Over time, the model is updated and fine-tuned to improve specific aspects such as grammar, coherence, and response quality. However, any update may not always result in an overall improvement in performance. Sometimes, updates can have unintended consequences like new biases, errors, or inconsistencies.
- Shifts in Objective: The objectives or priorities of the model may be modified over time, impacting its behavior and output quality. For example, the model may receive updates to prioritize certain types of information or respond in a more cautious or conservative manner.
The Potential Consequences of AI drift 🤖⚠️
Now, one might argue, “Isn’t it better for an AI to stay silent than spew misinformation or stoke controversy?” Sure, but remember, for every question it sidesteps, there’s a chance someone will turn to less reliable sources. And then the dreaded game of ‘misinformation hotline’ begins.
(This is one of the reasons we need to have unbiased AI search engines).
Or imagine a scenario where an AI system designed to assist with medical diagnoses begins to provide recommendations that prioritize cost-cutting measures over patient well-being. Or a climate management system that starts making decisions based on short-term economic gains rather than long-term sustainability goals. Continuous monitoring and evaluation are crucial to identify and reduce AI drift. But who will ensure that AI models like ChatGPT remain accurate, relevant, and intelligent in their responses?
OpenAI’s Superalignment Team to the Rescue 🌟🔧
In my previous article, I discussed OpenAI’s Superalignment team and their ambitious goal to keep AI on track as it continues to expand and outpace us:
To counter AI drift, the Superalignment team must navigate a myriad of challenges. One of these challenges lies in the fragility of Reinforcement Learning from Human Feedback (RLHF), a method used in machine learning. As AI becomes more advanced, accurately evaluating its performance becomes more difficult for humans. This limitation can undermine the effectiveness of RLHF and potentially adds to AI drift.
To counter this, the Superalignment team proposes “scalable oversight,” in which AI systems are used to monitor and regulate other AI systems. This approach leverages collaboration between AI and humans to minimize unanticipated behaviors and misaligned decision-making. By embracing scalable oversight to improve training procedures, the team aims to mitigate risks of AI drift and and enhance system accountability.
But the Superalignment team’s mission isn’t just about stopping a decline in the quality and reliability of AI output. It’s about cultivating systems that can understand us better and resonate with our intentions, values, and emotions. It’s about building AI that works in harmony with humanity.
The Challenge of Monitoring AI: Who watches the watchmen?
How does adding more AI models to monitor and help solve drift work, if AI is the problem? Well, remember how we said that the smaller AIs are more reliable and less likely to evince unexpected behaviours? And that it’s when they get unwieldy that they start acting out? Well, instead of having a larger overarching monitoring AI, imagine a cluster of smaller, focused, more accurate models, each with their own area of expertise, and each small enough to still be trained by humans using RLHF. That’s why it’s scalable.
Conclusion: Two Steps Forward, One Step Back 🔄
In summary, AI drift refers to the decline in performance or behavior of an AI model over time, and it can result in ChatGPT becoming “dumber” in terms of the quality and relevance of its responses. Several factors can contribute to AI drift, including issues with training data, updates or fine-tuning of the model, concept drift, and shifts in the AI model’s objectives.
In our rapidly evolving digital world, the concept of AI “drifting” away from its initial brilliance feels both unexpected and counterintuitive. We expect AI models to be honing their intelligence with every interaction. But with the revelation of this drift, the onus is on human users to remain vigilant.
Moral of the story? Keep chatting away with your AI pals, but maybe double-check their math homework for a bit. And remember, like us humans, not every day is a good day — even for our machine friends!
