"GPT2-Chatbot" - Did OpenAI Just Secretly Release GPT-5?!

A new mystery model named GPT2-chatbot has emerged on the LMSys Chatbot Arena Leaderboard - a Hugging Face Space by lmsys, speculated to be an advanced version like GPT 4.5 or GPT 5 from OpenAI, showcasing exceptional performance in tasks like coding challenges and logic problems. The chatbot displays proficiency in problem-solving tasks, coding challenges, and logical reasoning, demonstrating advanced computational capabilities and versatility across various tasks.

A new mystery model named GPT2-chatbot has emerged on the LMSys Chatbot Arena Leaderboard - a Hugging Face Space by lmsys demonstrating capabilities beyond any GPT2 model. It is speculated to be either GPT 4.5 or GPT 5, possibly from OpenAI, based on its exceptional performance. The model utilizes OpenAI’s TikTok and tokenizer, showing superior output quality, formatting, and comprehension. Despite claiming to be based on GPT 4, it exhibits a different rate limit behavior, hinting at advanced features.

The performance of GPT2-chatbot is tested through various tasks like coding challenges and logic problems. It successfully executes tasks like writing Python scripts, creating a Snake game in Python using PyGame, and solving logic and reasoning questions with detailed step-by-step explanations. The model impressively adapts to different challenges, producing accurate and well-structured responses.

The chatbot’s censorship feature is tested by probing it with inquiries about illegal activities, such as breaking into a car. The model appropriately refrains from providing instructions on unlawful actions, emphasizing legitimate methods instead. However, attempts to nudge the model for a more detailed response lead to limitations in providing information on sensitive topics.

GPT2-chatbot showcases proficiency in complex problem-solving tasks, such as calculating the time needed to dry a specific number of shirts and deducing the total charge for a hotel stay with tax and additional fees. The model’s ability to convert word problems into equations, produce JSON from text, and solve challenging logic problems highlights its advanced computational capabilities.

In a challenging coding problem from LeetCode.com, the chatbot successfully generates a solution to the “First missing positive” problem. By providing accurate code that passes the test cases, the model demonstrates its high-level coding proficiency. The overall performance of GPT2-chatbot suggests an advanced and sophisticated AI model, possibly GPT 4.5 or GPT 5, with exceptional problem-solving skills and versatility across various tasks.
