Researchers tested Large Reasoning Models on various puzzles. As the puzzles got more difficult the AIs failed more, until at a certain point they all failed completely.

Even without the ability to reason, current AI will still be revolutionary. It can get us to Level 4 self-driving, and outperform doctors, and many other professionals in their work. It should make humanoid robots capable of much physical work.

Still, this research suggests the current approach to AI will not lead to AGI, no matter how much training and scaling you try. That’s a problem for the people throwing hundreds of billions of dollars at this approach, hoping it will pay off with a new AGI Tech Unicorn to rival Google or Meta in revenues.
