Playground and Usage not showing same model

[severe saddle]

I'm using gpt-4 in the Playground but my Usage page shows gpt-4-0613 instead.
Is this just how gpt-4 is billed on the backend? How can I be sure gpt-4 is actually being used or if it's actually -0613?

[prisma void]

gpt-4 is an alias to whatever is the most recent GPT-4 model, which is currently that one

Thanks for the quick reply @prisma void !
What's confusing is gpt-4 gets updated and -0613 is a snapshot from that date. So why would it let me use gpt-4 in Playground if there's also a -0613 version to choose from, if it wasn't indeed different?

[prisma void]

both are the same

But OpenAI talks about them being different.
Per https://platform.openai.com/docs/models/gpt-4
gpt-4-0613 = "Unlike gpt-4, this model will not receive updates, and will be deprecated 3 months after a new version is released."

Can anyone else confirm whether these are the same or different?

[prisma void]

They are the same until a newer version is released

So gpt-4 isn’t being updated in a “live” fashion right now?
