Noam Brown is one of the key architects behind OpenAI's reasoning-model push and a foundational contributor to o1, the model family that established test-time compute as a powerful new scaling axis.
Therefore, one should take very seriously the statement that, despite the fact that the unpublished model has already found numerous solutions, with additional TTC (test-time compute), perhaps even million-dollar problems could be solved.
In short: there's no end in sight. The sky's the limit.
