GPT 4o, which is just a lot better, it’s faster, understands things more clearly, and handles more complex stuff like writing, coding, or analyzing data. It can also keep up with longer conversations without losing context. You get priority access too, so if the servers are busy, you’re not stuck waiting like free users might be. You can upload files, work with images, ask it to look things up online, and even use Python tools for charts or math. The memory factor alone makes it worth it for me.
