Beyond the perhaps superficial semantic distinction between "reasoning" and "pattern matching", there is a fundamental gap in the practical capabilities and behavior of these systems. You don't create an invention machine by iterating on an automation machine.
BREAKING: Apple just proved AI "reasoning" models like Claude, DeepSeek-R1, and o3-mini don't actually reason at all. They just memorize patterns really well. Here's what Apple discovered: (hint: we're not as close to AGI as the hype suggests)

What a fun and important collaboration with @HeyEpic to build such an important open-source tool for evaluating ChatGPT outputs in healthcare. Evaluation is a must to understand how we can integrate AI safely and effectively into our practice - check it out! @UW_ICU_DataSci
Another open-source tool is available in our AI Trust & Assurance Suite—this time to evaluate AI-generated patient summaries. https://t.co/NpMFJr8Z3o

Thanks for the mention, @HeyEpic! Our Clinical Informatics team is thrilled to be a part of this collaboration. @Majeans2011 @UW_ICU_DataSci @DrJoelGordon @p_kleinschmidt @uw_medicine
We’ve been working with organizations like @uwhealth to help define how AI should be tested, trusted, and used safely in healthcare. Our joint report highlights the work ahead: local validation, transparency, and the need for standards that reflect real care.
