How do I get access to GPT-5 ?

How do I get access to GPT-5?  It is currently unclear when or if GPT-5 will be released, as its development has not been officially announced by OpenAI or any other organisation.

However, if and when GPT-5 is released, it is possible that access to the model will be limited to selected organisations or individuals, or require a subscription or licence fee. It is also possible that OpenAI or other organisations will release a public version of GPT-5 that is freely available, as was the case with GPT-4.

If you are interested in using natural language processing (NLP) models such as GPT-5, there are currently several other NLP models available for use, such as GPT-3, BERT and XLNet, among others. Some of these models can be used via API services provided by OpenAI and other organisations, while others can be downloaded and run locally on your own hardware. It should be noted, however, that using large language models can require significant computing resources and technical expertise and is therefore not feasible for everyone.

To the best of my current knowledge (deadline September 2021), GPT-5 has not yet been officially released and there is no information on how to access it. It is currently unclear when or if GPT-5 will be released, as its development has not been officially announced by OpenAI or any other organisation.
