ChatGPT 4 – Free on my MacBook Pro

***UPDATE***

December 7, 2025

Since I wrote the above ChatGPT has moved on, now offering version 5 for free. This version continues on being awesome for all sorts of subjects. The only problem with the free version is for complicated problems when you feel like you must continue on, you may be cut off with a message that you have reached your limit for several hours. This of course is frustrating. ChatGPT 5 is so good, and I need it so often I upgraded to ChatGPT 5 Plus. They give you the first year at a bargain price and there is seemingly no limit to how many chats you can initiate in a day with the Plus version. Personally I have been nothing less than astounded at how good it is at understanding your problem, summarizing it succinctly (a great help for clarity) and then going on to show you the answer in as much depth as you can take!
