An unexpected new player, the "GPT2-Chatbot," has captured the attention of the AI community by possibly outperforming OpenAI's renowned GPT-4 model, according to recent reports.
Unresolved Origins of 'GPT2-Chatbot'
According to Forbes, "GPT2-chatbot," an AI chatbot, debuted inconspicuously on LMSYS Chatbot Arena, a platform that examines different AI systems.
Uncertain as to its origins, the bot's moniker alludes to OpenAI's GPT-2, a substantial language model that predates the lab's more sophisticated GPT-3 and GPT-4 systems, which are employed to operate ChatGPT and other similar applications.
Potential Beyond OpenAI's GPT-4
Compared to GPT4, OpenAI's most sophisticated AI system, the mystery chatbot seems to match and possibly surpass its skills.
VentureBeat reported that, however, it fails to meet the anticipated standards of OpenAI's highly anticipated model, GPT-5. This has sparked speculation that it may be a successor to the company's current system, GPT-4, possibly referred to as GPT-4.5.
Sam Altman's Intriguing Connection
Following a post on X in which the lab's CEO and cofounder Sam Altman admitted to having a "soft spot for gpt2," speculation increased about whether OpenAI developed the model. Gizmodo says the anonymous "GPT2-chatbot" has received considerable attention in online AI communities.
One X user says the bot almost wrote code that made an exact copy of the mobile game "Flappy Bird." Reddit users argue in long threads whether the "GPT2-chatbot" came from OpenAI, Google, or Anthropic. These allegations are unfounded, but statements made by Altman have only fueled the flames.
The "GPT2-chatbot" can be tried out for free on the LMSYS Org website. Just click on "Arena (side-by-side)" or "Direct Chat" in the dropdown menu. LMSYS Org's policy blog says that some AI model devs can test private models before making them available to the public.
