ChatGPT became publicly available in late 2022 and ever since there seems to have been a race in this AI domain. I have not really been really into the whole thing but am getting really interested.

A very high level timeline (will need to update / correct at some point)

2017 – some scientists at Google publish a paper, “Attention is all you need” proposing a new model called Transformer

2018 – GPT-1 with 117M Parameters

2019 – GPT-2 with 1.5B

2020 – GPT-3 175B

2022 – we have RLHF, Reinforcement Learning from Human Feedback, and ChatGPT

2023 – GPT-4 1T

2024 – GPT-4o
