Chatgpt’s vision capabilities has video feature on iPhone device. There’s a demo of this on youtube if you look for “Live demo of GPT-4o’s vision capabilities”. Can’t link here since there’s restriction on posting links.
However, I don’t find that feature in chatgpt client on my Macbook. (Chatgpt Version 1.2025.098 (1744417605).
I’m subscribed to pro version.
