Sorry, but I don’t understand the FUD in this thread.
For those who are interested in transitioning from Codex to GPT 3.5, it did not take me very much effort to recreate my simple code completion attempts, as indicated in this thread.
Did Open AI shut down Codex on a short notice? Yes. Could they have done a better job on the transition docs before notifying users? IMO yes. Does the change justify bitter FUD posting in this forum? IMO no.
