Summary: A study on OpenAI’s GPT-4 AI model suggests it displays rudimentary reasoning abilities. Researchers subjected GPT-4 to diverse challenges, including revising code to draw a unicorn. While some argue this indicates reasoning, others claim AI’s responses are probabilistic and lack true understanding. Testing AI’s intelligence rigorously is essential to resolve the debate over its capabilities. Despite some progress, designing reliable, reproducible AI intelligence tests remains a challenge, given AI’s ability to access vast training data. Calls for AI regulation are increasing as AI systems become more capable. Rigorous benchmarking is vital to assess AI’s true capabilities.
