GPT releases model tunes using a month-day versioning system.

For GPT-4 there are 2 releases

• 0314 - Original Release, good at math
• 0613 - Recent update, tagged to "GPT-4" in chat gpt and "gpt-4" in API calls.

If you want 0314 you need API access, Azure, or know someone sharing access.

It is entirely possible to use a version of GPT-4 that is very much like the version we used on opening day. just a little diy

I don't know why thier tune is bad for 0613. Altman has made some statements they dont say much,.
