If chatgpt moved to chat. All the gpt domains will be a waste of time and money
ChatGPT is not the original OpenAI link anyway.
Although it's popularly known as ChatGPT, the URL is: chat.openai.com
AI.com also redirects to chat.openai.com.
To guess whether or not GPT domain name hype will go away, we should first examine where the term GPT comes from.
To the best of my knowledge, GPT, which is the abbreviation of Generative pre-Trained Transformer, is a Transformer based deep learning AI language model. Transformer is another term, which was first introduced by the researchers of Google Brain in 2017. OpenAI's version of Transformer based language model is called GPT.
So basically GPT domain name hype is not based on the URL (domain name) of OpenAI's AI product, rather the hype is connected to what the underlying technology is called.
Which means, even if OpenAI fully migrates to AI.com or Chat.com, GPT name hype will still remain for a while, until a different and better language model is introduced with a different term, either by OpenAI or others.
Having said all that, I personally didn't invest in any GPT prefix/suffix domain names. Some people are making money with these, but my understanding is, these sort of hypes are usually short lived.
So, unless OpenAI keeps updating GPT-N perpetually and ultimately reaches to what is commonly known as
AGI Singularity with GPT technology, GPT hype will probably fade away.
On the other hand, if (and it's a huge if) OpenAI can achieve AGI Singularity with GPT technology alone, then the term GPT will become immortal.
However, with any possible AGI Singularity, the entire economy will fall apart. No one will have any jobs anymore and all of us will be at the mercy of OpenAI, Microsoft and our new AI overlord. So at that point, domain names will probably not mean much anymore anyway.
Hope this clarifies the confusion somewhat. Or did I just make everything more confusing?
Anyways, happy domaining
