How much did you use the original GPT-4-0314?

(And even that was a downgrade compared to the more uncensored pre-release versions, which were comparable to GPT-4.5, at least judging by the unicorn test)

I don't recall the original version we used unfortunately :(

in our case, the bump was actually from gpt-4-vision to gpt-4o (the use case required image interpretation)

It got measurably better at both image cases and text-only cases
