This is something I am considering using on my website, of course I will have to wade through all the "geek stuff first". It is a project on GitHub

https://github.com/xtekky/gpt4free

And it lets you indirectly access GPT4 through Bing I believe. Open.AI has apparently threatened a law suit already.

If anyone else is interested in implementing this please let me know.

Thanks,

Chris
