In the world of large language models (LLMs) like ChatGPT, Claude, and others, we’ve seen some incredible advancements in AI. These models are now used daily across industries to assist with everything from answering questions to generating creative content. However, there’s a simple task that stumps them: counting the number of "r"s in the word “strawberry.”
Yes, you read that right. AI, with all its powerful capabilities, struggles with counting the letters in a word. This limitation has sparked debate about what LLMs can and cannot do. So why does this happen, and more importantly, how can we work around these limitations?
Let’s break it down.
Why AI Fails at Counting Letters
At the core of many high-performance LLMs is something called a transformer architecture, a deep learning technique that enables these models to understand and generate human-like text. These models aren’t simply memorizing words—they tokenize the text, meaning they break it into numerical representations (tokens).
For example:
- The word “hippopotamus” might be broken down into tokens like “hip,” “pop,” “tamus,” and so on.
- In this process, individual letters are often ignored, making it difficult for LLMs to accurately count characters in a word like “strawberry.”
The Tokenization Problem
When you ask an AI to count the number of "r"s in “strawberry,” the model tries to predict the answer based on patterns, rather than looking at the individual letters. This token-based prediction is great for generating text, but not for simple tasks like counting letters.
This highlights a fundamental limitation: LLMs don’t process information like humans do. They don’t directly "think" in letters; they predict outcomes based on tokenized text.
The Workaround: AI’s Strength in Structured Text
Here’s the good news: While LLMs struggle with tasks like counting letters, they excel at understanding structured text. That’s why they perform well when working with programming languages like Python.
For example, if you ask ChatGPT to write a Python script to count the number of “r”s in “strawberry,” it will do so correctly.
Here’s a simple Python code you could use:
By asking the model to switch from plain language to code, you can help it overcome its limitations. The broader takeaway is that, for tasks requiring logic or computation, prompting AI to use code (or other structured methods) is a great way to achieve accurate results.
Why Understanding AI’s Limitations Matters
The “strawberry” problem might seem minor, but it serves as an important reminder: AI models are not human-like intelligence. They are predictive algorithms capable of pattern recognition, but they do not truly “think” like humans.
As AI becomes more integrated into our daily lives, it’s essential to understand these limitations and manage our expectations. AI can accomplish a lot, but knowing where it falls short will help us use it more effectively.
Conclusion: Using AI Responsibly
AI is not a flawless solution to every problem, and as users, we need to be aware of its strengths and weaknesses. By understanding the “strawberry” problem and leveraging the power of structured text and programming, we can make the most of LLMs while navigating their limitations.
