Beyond Bigger Models: Recursion As The Next Scaling Law In AI

Recursion at inference time—rather than simply scaling model size—may be the next breakthrough in AI reasoning. Recent research on Hierarchical Reasoning Models (HRM) and Tiny Recursive Models (TRM) demonstrates that recursive architectures using shared weights can solve complex reasoning benchmarks like Arc Prize with minimal parameters, outperforming massive traditional LLMs.

How to Build the Future: Demis Hassabis

Demis Hassabis predicts AGI by around 2030 and argues that while current large-scale pre-training and reinforcement learning form the foundation, breakthroughs in continual learning, memory consolidation, and introspective reasoning are still required to achieve true artificial general intelligence.

François Chollet: ARC-AGI-3, Beyond Deep Learning & A New Approach To ML

François Chollet predicts AGI will arrive around 2030 but argues current deep learning is fundamentally inefficient; through his lab NDIA, he is pioneering symbolic program synthesis as a more optimal alternative focused on human-like skill acquisition efficiency, while acknowledging that LLM-based systems will first dominate domains with verifiable reward signals like coding.
