If you, like me, are annoyed by Canvas, it turns out you can disable it for all new chats in Customize ChatGPT.
Reasons why it annoys me:
1. I usually work with multiple files at the same time, but in Canvas, only one will ultimately be modified.
2. The most insidious part - sometimes if ChatGPT struggles with a coding task, I switch from 4o (which is much faster and sufficient 95% of the time) to o3 (which is slower but much better in logic and coding). So if Canvas has automatically turned on somewhere at the top, you can forget about o3; it won’t activate.
