How do you reconcile issues such as the o1 pro model erroring out every 3rd attempt at an extremely large context? (that still fits but is near the limit) Every time I try to get this thing to read my codebase and onboarding docs (about 40k line angular codebase) it is "pull your hair out" failing leading to frustration.
