OpenAI stated that ChatGPT is fine-tuned model from the GPT-3.5 series

GPT-3 is published by a group of 31 engineers and researchers on May 28, 2020

GPT-2 is published in February 2019.

The most foundational paper, "Attention Is All You Need" is published on 12 Jun 2017 and cited more than 60,000 times.
