Do you have API access? If so, are you able to find a prompt/response pair where the model `gpt-4-0314` (supposedly the original publicly released version) does worse than `gpt-4` (the current model)? If you don't have API access, you can share some transcripts where the latest version of `gpt-4` seems to have performed worse than it did in the past, and I will try them myself against `gpt-4-0314` and post the results.

Interesting, please keep up abreast of your encounters with the good GPT.
