The video explores a pivotal moment in artificial intelligence, highlighting a shift from the dominance of large language models (LLMs) to a new era of diverse approaches and renewed ambition toward artificial general intelligence (AGI). It opens by noting how the initial excitement around LLMs, especially after the release of ChatGPT, led to a convergence of research efforts and a closing of the open frontier in AI. This focus on LLMs, while advancing certain capabilities, also limited exploration of alternative paths and slowed broader progress toward AGI. Now, as the limitations of LLMs become clearer, major AI labs are making new bets and exploring different architectures.

DeepMind is positioned as a central player in this new phase, with co-founder Shane Legg reiterating his long-standing prediction of a 50/50 chance of achieving “minimal AGI” by 2028. Legg defines minimal AGI as an artificial agent capable of performing the full range of typical human cognitive tasks without surprising failures. He emphasizes that this is just the starting point, and that reaching the extraordinary feats of human intelligence—such as groundbreaking scientific discoveries or artistic achievements—will require further breakthroughs. DeepMind’s roadmap involves integrating advances in language models, world models, and image understanding into a unified system that could serve as a candidate for proto-AGI.

In contrast, Yann LeCun, a foundational figure in modern AI, argues that AGI is a flawed concept. He contends that human intelligence is not truly general but highly specialized, and that the idea of a universal intelligence is an illusion. LeCun’s main critique of current LLMs is that they rely too heavily on memorization and lack the ability to form higher-level abstractions, such as planning or meta-learning. To address this, he and his colleagues at Meta have developed a new architecture called Joint Embedding Predictive Architecture (JEPA), which aims to help models learn abstract representations rather than focusing on pixel-level or word-level details.

JEPA represents a significant departure from traditional generative models. Instead of predicting missing words or image patches, JEPA trains models to predict compressed feature vectors that capture the essence of a scene or action. This approach encourages the model to develop conceptual understanding and abstraction, making it more efficient and potentially more powerful for real-world tasks. However, as a first-generation model, JEPA is not yet as accurate as existing methods, and it is not generative—meaning it requires additional interpreter modules to translate its internal representations into human-understandable outputs.

The video concludes by reflecting on the ongoing debate between DeepMind’s Demis Hassabis and Yann LeCun regarding the nature and achievability of AGI. Hassabis maintains that general intelligence is possible and that the human brain and advanced AI models are, in theory, capable of learning anything computable. He sees AGI as a practical and achievable goal, while LeCun remains skeptical. The broader takeaway is that AI research is entering its most exciting and experimental phase yet, with a proliferation of new architectures, riskier bets, and a return to open-ended exploration. This diversity of approaches, rather than a single path, is likely to drive the next wave of breakthroughs in artificial intelligence.
