UnverifiedYann LeCun believes that achieving true artificial general intelligence (AGI) cannot rely solely on large language models, but also requires building world models capable of internally simulating the laws governing the physical world.78% similarUnverifiedThere is a deep divide in academia over the path to AGI: one camp believes that by continuing to scale up model size, existing architectures will eventually give rise to general intelligence; the other holds that the Transformer architecture has fundamental capability limits and an entirely new computational paradigm is needed.74% similarUnverifiedResearchers such as Yann LeCun advocate building AI architectures based on world models, arguing that language modeling alone cannot achieve genuine understanding and safe decision-making.72% similarUnverifiedCurrent AI (large language models) does not possess genuine understanding of individuals; its essence is pattern matching rather than true understanding.71% similarUnverifiedA deep understanding of the Transformer architecture, model fine-tuning engineering practices, and mathematical programming fundamentals are the key steps in transitioning from an API caller to a model builder.70% similar
