Resolves YES if OpenAI publicly acknowledges this data being particularly useful for training further iterations of GPT4 or different successors, or trustworthy leaks (my credence), stating that this was an integral component of success.

Resolves NO if other factors (architecture, training techniques, other token sources) are judged as having been largely more important.

Resolves N/A if market closes and question is unsanswerable due to insufficient information being public.
