Pankaj Singh 30 Apr, 2024 • 6 min read


Have you heard about GPT2-chatbot? It has set the whole town abuzz!

This new artificial intelligence (AI) model has recently emerged and is causing quite a stir in the tech community. This enigmatic model has been released without official documentation, leading to speculation about its origins and capabilities. However, with its impeccable performance compared to other models, everyone, from Sam Altman to Rowan Cheung, is tweeting and talking about the GPT2-chatbot. 

What’s interesting is how it’s being discussed across different circles.

Some marvel at its potential to revolutionize natural language processing, while others are cautious, expressing concerns about its origin. The lack of official documentation adds an air of mystery to the whole thing, fueling even more speculation. It’s like the tech world’s version of a viral sensation, with everyone trying to decode its inner workings and implications. 

Are all these speculations about GPT2-chatbot true, or is there any firm theory about this new model? Sam Altman, the CEO of OpenAI, tweeted, “I do have a soft spot for gpt2,” which fueled the speculation that this new model is a significant advancement. 

Also, we comprehend that this is something to talk about. 


GPT2-chatbot: An Overview

The new model, “GPT2 chatbot,” is on the Chatbot Arena website. According to industry mavens, it has outperformed other state-of-the-art models like GPT-4 and Claude Opus in various reasoning tasks, coding challenges, and even AI art generation. 

Moreover, there is speculation that this “GPT2-chatbot” could be an early version of GPT-4.5 or GPT-5, as it seems to exhibit improved capabilities compared to GPT-4.

Also, Andrew Gao, an AI researcher and Stanford University student, said, 

“It’s obviously impossible to tell who made it, but I would agree with assessments that it is at least GPT-4 level.”

As per the users’ experiments, the “GPT2 chatbot” model appears to have better reasoning abilities, as demonstrated by its ability to solve simple puzzles that other models struggled with.

In coding tasks, such as creating a simple game in JavaScript, the “gpt2 chatbot” outperformed GPT-4 Turbo by producing a functional game from scratch.

While the model excels in certain areas, there are also instances where it underperforms or fails the “GPT2 chatbot” model to provide satisfactory results, suggesting that it may not be a significant leap forward like GPT-5.

Regarding the naming convention, the name “gpt2 chatbot” is peculiar. It intentionally throws people off, leading to speculation about OpenAI’s motives for releasing this model covertly.

Some theories suggest that this could be a test or preview version of GPT-4.5 or an improved variant of GPT-4 rather than a completely new model.

More comprehensive benchmarking and testing are needed to fully understand this “GPT2 chatbot” model’s capabilities and limitations.

Measuring Matrix of GPT2-chatbot

As I have mentioned about the speculation of the GPT 2 Chatbot, you might be pondering whether this GPT is worth exploring or not. I would suggest you try the model yourself to see the difference. Now, let’s talk about the matrix on which the GPT2 chatbot is being measured:

Advanced Reasoning Skills

The “GPT2-chatbot” has demonstrated an impressive reasoning ability in various online instances. It has been observed to answer complex AI questions with a remarkably human-like tone, which sets it apart from many of its contemporaries.

For instance, as Everartai’s founder, Pietro Schirano, tweeted, this model is limited to showing great reasoning and quickly answering challenging questions. 

Math Proficiency

In a testament to its mathematical prowess, the “GPT2-chatbot” solved a problem from the International Math Olympiad (IMO) in a single attempt. While it didn’t solve all the problems on the IMO test, this achievement is still a significant indicator of its advanced mathematical capabilities.

For instance, according to the techno-optimist Andrew Gao, the GPT2-chatbot can solve the International Math Olympiad (IMO) problem in one shot. After experimenting with multiple prompts and comparing them with GPT 4, it was evident that GPT-4 gives a much more vague answer. 

I am providing a question for both ChatGPT 3 and GPT2-chatbot. Let’s see how it goes:

Superior Coding Skills

A reliable source from an AI startup has confirmed that the “GPT2 chatbot” outperforms the latest version of GPT-4 and Claude Opus in coding tasks. The source says, “It does better than GPT4 or Claude Opus on all our hardest coding prompts.

ASCII Art Mastery

In an unexpected display of creativity, the “GPT2-chatbot” has shown exceptional skills in ASCII art. It has been described as being “miles ahead of any other model” in this area.

For Instance: Let’s create an ASCII ART POLAR BEAR and compare it with other models.


The Enigma of Its Origin

The absence of official documentation has confused the AI community about the model’s creators. The most popular theories include the possibility of an early release of GPT-5 by OpenAI for benchmarking purposes or the 2019 version of OpenAI’s GPT-2, finetuned with modern assistant datasets.

How to Experience the “GPT2-chatbot”?

Curious users can try the “GPT2-chatbot” for free on the direct chat platform at the Chatbot Arena website. Remember that access to the model may be limited, with slower response times and a maximum of 8 turns per conversation.
