I tested web ChatGPT Pro.... Coming from Plus...
I am posting this because i wish someone else had posted something similar for me to find when i researched Plus vs Pro...
I am not a programmer, i am in a project where i need to write a very precise and well defined business text, and im not native English so ChatGPT is a good help to have.
But I just discovered that the chatGPT has, surprisingly, same small chat window context size as the Plus. I do text editing in the canvas and discuss different strategies with chatGPT who has a good overview of the whole text (10K words). It works well for about 3-4 hours and then it start to behave weird. Above 15K word or 20K tokens (ChatGPT Token Counter addon for Chrome), the chat decays rapidly, for it to be no useful anymore. Sure i can just start all over again, but it is time consuming and not optimal.
One good ting with Pro subscription, is that they allow for more text in the canvas, that is a big plus. But Pro thinking does not support canvas, but pro thinking is of no use for me as it takes forever to get a reply anyway. I use it for deep reviews of my text sometime though.
5.4 Thinking has a "Heavy" level above "Extended", which seems to be as fast as "Extended" so that is the one i'm using for the editing and everything else.
