GPT-4's Secret Has Been Revealed

According to ithinkbot.com, GPT-4 is based on the Mixture of Experts architecture and has 1.76 trillion parameters. It is rumored to be based on eight models, each with 220 billion parameters, which are linked in the Mixture of Experts (MoE) architecture. The idea is nearly 30 years old and has been used for large language models before, such as Google's Switch Transformer.

The information about GPT-4 comes from George Hotz, founder of Comma.ai, an autonomous driving startup. Hotz is an AI expert who is also known for his hacking past: He was the first to crack the iPhone and Sony's Playstation 3. Other AI experts have also commented on Hotz's Twitter feed, saying that his information is very likely true.

Hotz also speculated that GPT-4 produces not just one output, but iteratively 16 outputs that are improved with each iteration. The open-source community could now try to replicate GPT-4's architecture and train their own models.
