I don't think this is correct, one of my colleagues made a MVP using ChatGPT a month ago (I don't know how it works internally, but it was fully integrated with our system, a multi job posting system).

My hunch is selenium.l but I haven’t taken a look at this any more than the title and Op’s comment.

Hey, OpenAI provides an API here https://openai.com/api/ which give you access to a host of cool features and models. It's what we use.

Just to be clear those are APIs for GPT-3 not ChatGPT specifically.

I've heard that text-davinci-003 is better than ChatGPT at most tasks. They're probably using that.

is there a competing open-source version of this model I could run locally?

I don't believe there's one just _yet_.

A quick google search reveals GPT-Neo and GPT-J as being open source. But haven't yet tried them, so can't vouch if they're as good.

One possible API is https://github.com/acheong08/ChatGPT

It uses a lurky captcha solving service, as well as chromedriver, which bin patches chrome so that chrome is automatable in a hard to detect way (off the shelf selenium is detectable by websites), but it works quite well, if you can manage to get it running. We've got a ChatGPT slackbot setup, which is quite a bit of fun in a group setting.
