Is ChatGPT 175 Billion Parameters? Technical Analysis

A technical blog post by Oren Leung (published March 2023) that investigates whether ChatGPT is truly built on a 175-billion-parameter model, examining architectural evidence and publicly available information about OpenAI's GPT models. The piece challenges the widely repeated 175B parameter claim as it applies specifically to ChatGPT (as opposed to the base GPT-3 model), and sparked discussion in AI communities. The content was hosted on Super (super.site) but is no longer accessible.
