Large Language Models (LLMs) are like smart assistants powered by Advanced technology. They can generate text, answer questions, and even hold conversations. However, there are some common misconceptions about what they truly are and what they can do.
What is a Large Language Model?
At its core, a large language model is a computer program designed to predict the next word in a sentence based on the words that came before it. Think of it as a really advanced autocomplete feature, much like the suggestions your phone gives you when you're texting. But these models are much more complex, having been trained on vast amounts of text from the internet and other sources.
The "Bare-Bones" LLM
The simplest version of an LLM is what’s known as a "bare-bones" model. This type of LLM relies solely on mathematical calculations to figure out which word should come next in a sentence. It doesn’t know anything in the way humans do; it just processes patterns in the data it’s been given.
Imagine your friend's pet goldfish trying to answer your questions. Your fish doesn't really know anything; it just swims around in circles and does fishy things. Similarly, a bare-bones LLM just cranks out words based on the patterns it recognizes. It doesn't have thoughts, Beliefs, or feelings.
Conversational Agent
TheNow, let’s add a little flair to the bare-bones model. When we put the LLM into a more interactive system, it becomes what we call a "conversational agent." This agent can engage in a back-and-forth dialogue with humans, similar to how you might chat with a friend over coffee.
However, just because you can chat with this agent doesn’t mean it’s truly aware or has beliefs like you and I do. When the agent responds, it’s merely following the patterns it learned during training. So, if you ask it a question, it pulls from its memory of text patterns and gives you the most fitting answer it can find—kind of like a parrot that mimics its owner without really understanding the words.
Beliefs and Behavior
One major point of confusion is about the word "belief." When we say someone has beliefs, we usually mean they think or feel something based on their experiences and interactions with the world. A belief shapes how people act and react.
So, can we say that our conversational agent has beliefs? The answer is no. It’s all about context. Belief, in the human sense, involves being part of the world and reacting to it. The agent doesn’t live in the world; it cannot peek into your fridge and tell you whether you have milk or not. Instead, it merely generates responses based on learned patterns from a text-based world.
Beyond Text: More Advanced Systems
As technology progresses, we develop more advanced LLMs that can do more than just respond to text. These can include systems that take visual input, like cameras, and interact in environments, both real and virtual.
Now, imagine a robot that can take a look around your kitchen to help you find that missing spatula. These advanced models can gather various types of data and respond in complex ways. With these systems, we can start talking about beliefs again, but we still need to tread carefully. Just because a model can observe the world doesn’t mean it really "understands" what it sees.
The Hierarchy of Understanding
Think of LLMs like a roller-coaster ride: the higher you go, the more thrilling it becomes. The bare-bones model is at the bottom—it's simple but lacks depth. As we build on this foundation and add more capabilities, we reach higher levels where the model can interact with the world in richer ways.
At the top of this hierarchy, we have systems that can integrate various inputs and act on them in real-time. These advanced systems might look and sound intelligent, but we should be careful with how we describe their actions. Just because a robot can play chess doesn't mean it dreams of being a grandmaster; it simply follows rules programmed into it.
The Dangers of Anthropomorphism
A common mistake people make is thinking of LLMs and robots in human-like terms. When we say an LLM "knows" something or has "beliefs," it sounds like we’re giving it a personality or a mind of its own. While it’s fun to think about, it leads to misunderstandings about what these systems can and cannot do.
For example, if you say, "ChatGPT thinks you're a great cook," it might sound flattering. It’s easy to forget that "ChatGPT" isn't actually thinking—it’s just outputting a response based on patterns. The real chef in this scenario is you!
Caution is Key
When we discuss LLMs and their capabilities, it’s essential to maintain a clear view of what they really are. They are tools designed to assist us, generate text, and answer questions. They do not have minds or beliefs, nor do they interact with the world in the way humans do.
As we embrace new technology, we need to remind ourselves to keep our expectations realistic. Sure, it’s fun to imagine a future where robots might have thoughts and feelings, but we aren’t there yet. In fact, we might not ever reach that point, and that's totally okay!
Conclusion: Keep the Humor Alive
In conclusion, LLMs are fascinating and powerful tools that can help us navigate the sea of information we have today. They can provide answers, suggest ideas, and even tell jokes (with varying success). But let’s not confuse them with our human experiences, feelings, or beliefs.
So next time you find yourself chatting with an LLM, remember: you're talking to a supercharged program that’s done a lot of reading but has never had a cup of coffee to drink. And while that may not be nearly as exciting, it certainly keeps the conversation interesting!

Title: Still "Talking About Large Language Models": Some Clarifications
Abstract: My paper "Talking About Large Language Models" has more than once been interpreted as advocating a reductionist stance towards large language models. But the paper was not intended that way, and I do not endorse such positions. This short note situates the paper in the context of a larger philosophical project that is concerned with the (mis)use of words rather than metaphysics, in the spirit of Wittgenstein's later writing.
