GPT4V vs web GPT4 interface

For those who is working on images API with GPT4V, I am curious is GPT4 web interface with upload images is same as the GPT4V via API?

I wonder if there is OpenAI official evidence for that, thank you!

What is GPT4 web-interface? Do you mean ChatGPT?

yes, ChatGPT4 vs GPT4V via API for this comparasion.

As far as I know the main difference is ChatGPT has its own system message.
