GPT stands for "Generative Pre-Training" and was introduced in this paper from OpenAI in 2018. On February 14th 2019, OpenAI announced GPT-2, which became famous within the machine learning community for producing surprisingly coherent written text samples. It used 1.5 billion parameters.
On the 28th of May, 2020, OpenAI released GPT-3, a 175 billion parameter model, widely regarded to have impressive language generation abilities.
If GPT-4 is created, when will it be announced?
This question resolves on the date during which OpenAI staff publish a blog post, a paper, a video, or a document of any kind, describing GPT-4 or some performance results from GPT-4. In case OpenAI does not explicitly refer to the relevant model as GPT-4, members of the community, community moderators or admin will do a strawpoll on the /r/openai subreddit and ask:
In your opinion, is it roughly correct to say that this model is the successor to GPT-3?
After 1 week, the majority answer wins with a tie counting as "yes". If OpenAI does not release GPT-4 by January 1st 2023, this question resolves ambiguously.
