API calls for model gpt-4 receive responses from model gpt-4-0314

Going through my billing info today, I realized that every api call I’ve made for gpt-4 has been responded to with content generated with the gpt-4-0314 model. I found a couple of threads where it appears something similar has happened to others as well, but none of them reached any sort of resolution. Has any encountered and been able to resolve this particular issue?
