ARC-AGI-3 leaderboard exposes LLM reasoning limits
The ARC-AGI-3 leaderboard reveals a massive performance gap between state-of-the-art LLMs and human-level fluid intelligence. Even models like Gemini 3.1 Pro and Claude Opus struggle to solve simple 2D visual puzzles, highlighting their lack of grounded mental models despite their vast textual knowledge.
LLMs are elite 'engines' for text but 'blind' to the physical world, making them highly specialized tools rather than general intelligences. High test-time compute costs yield negligible scores on puzzles children solve easily, confirming François Chollet's hypothesis that LLMs are stochastic parrots without true adaptive reasoning. Human intelligence's edge lies in 20-watt efficiency and 3D spatial grounding, not token processing speed, suggesting AGI should be viewed as a 'complementary specialized intelligence' rather than a human replacement. The 'brain in a jar' metaphor highlights the critical missing link: sensory-motor grounding.
