I have been at OpenAI for 7 years. I overlapped with the “concerned former employees.” Their claims display lack of larger context and lack of maturity. I mean, we argue about GPU allocation all the time! Sam’s job is to decide. Ofc someone will be disappointed. Grow up.

No, we haven't made GPT-4 dumber. Quite the opposite: we make each new version smarter than the previous one. Current hypothesis: When you use it more heavily, you start noticing issues you didn't see before.

GPT-3 is amazing at complex tasks like creative writing and summarizing. But it's surprisingly bad at reversing words. 🤔 The reason is that GPT-3 doesn't see the world the way we humans do. 👀 If you teach it to reason, it can get around its limitations to get really good. 💡

Around this time 3 years ago, early 2020, we started testing the OpenAI GPT-3 API with the first external users. It was really hard to get anyone to try it, let alone build on it. So much has changed since then, but still feels like we're in the early days.

GPT-4 is very GPU hungry. We’re going to invite people as fast as possible, while providing a good experience for everyone. That said, you can try it right now on ChatGPT Plus.

Lovely application of GPT-3. Helping humans where they struggle, so they can focus on the things they're good at:

I mentor a young lad with poor literacy skills who is starting a landscaping business. He struggles to communicate with clients in a professional manner. I created a GPT3-powered Gmail account to which he sends a message. It responds with the text to send to the client.

Tokens are chunks of characters. For example, the word “alphabet” gets broken up into the tokens “alph" and "abet”. Short and common words like “the” are a single token.

The real thing OpenAI did is make it way easier to be a micro-entrepreneur. A lot of companies that anyone can start and make a good living off of that don’t need venture money now. It’s actually quite delightful.

So close! It manages to reverse the letter sequence, but fails at removing the spaces in the last step. It's the tokenization striking again.
