It also has a context window of 8192 tokens, which is 2x any of the instruction-following models available in the API. Also the model is internally labelled “text-davinci-002-render”, which would seem to imply it doesn’t include RLHF tuning (unique to 003).

Fine-tuning process and 8192 token context window
By

It’s clearly a very different fine-tuning process, which they talk about in some detail in the announcement. Also the context window is 8192 tokens, double any of the text models available through the API.

Reliable way to get current date: ask first 50 words of prompt

Sliding window of 8192 tokens confirmed in latest update

See my update in the replies — I now believe it's simply a sliding window of length 8192 tokens.

Token limit failure at ~8192 tokens with test input
By
–
That's why I added the "All systems go" part in the first example — to show the input wasn't ignored after the long string of tokens. Combined with the fact it fails after ~8192 tokens total (see update in replies) this seems conclusive.

A trick to make it accidentally reveal the current date

While trying variations of this prompt, I discovered a somewhat reliable way to make it accidentally reveal the current date:

ChatGPT pretends ignorance of current date, but can be tricked into revealing knowledge.

OpenAI's ChatGPT appears to be designed to pretend that it does not know the current date, even though it does. If you're clever, you can make it reveal that it knows. Ask about this, and it will continue to deny knowing in spite of its prior answer.
