A Remarkable Step Towards AGI

While recent AI successes have been focused on specific tasks, OpenAI’s new language model GPT-4 shows promising signs of broader intelligence

Intelligence is a complex and elusive concept that has fascinated psychologists, philosophers, and computer scientists for a long time. While there is no universally accepted definition of intelligence, it is generally agreed that it encompasses a wide range of cognitive abilities and skills, extending beyond specific domains or tasks. The field of Artificial Intelligence (AI) has long aimed to create systems that exhibit such broad intelligence. While recent AI successes have been focused on specific tasks, the new language model GPT-4 developed by OpenAI shows promising signs of broader intelligence.

The rise of Language Models

In recent years, a significant breakthrough in AI research has been achieved through large language models (LLMs). These models, based on the Transformer architecture, have been trained on massive amounts of textual data from the web. GPT-4, an early version of this model, demonstrates remarkable capabilities in various domains and tasks, ranging from abstraction and comprehension to vision, coding, mathematics, medicine, law, and understanding human emotions and motives.

GPT-4’s impressive performance

Through natural language queries (prompts), researchers interacted with GPT-4 during its early development. Preliminary examples show GPT-4’s ability to write a proof of the infinitude of primes in the form of a poem, create a unicorn drawing using TiKZ (a graphics language), generate complex animations in Python, and solve high-school level mathematical problems. The outputs produced by GPT-4 are virtually indistinguishable from or even better than what humans can achieve.

Comparison with previous models

Comparisons are made between GPT-4 and previous LLMs, particularly ChatGPT (an improved version of GPT-3). While ChatGPT performs reasonably well on given tasks, it falls short when compared to the outputs produced by GPT-4. GPT-4’s generality and its ability to perform at or beyond human-level on a wide spectrum of tasks make it a significant step towards achieving Artificial General Intelligence (AGI).

GPT-4’s limitations and biases

Despite its impressive capabilities, GPT-4 still has limitations and biases, as is the case with other LLMs. It may exhibit hallucinations or make basic arithmetic mistakes. While it lacks certain aspects of intelligence such as planning and continuous learning from experience, it can learn within a session. GPT-4’s patterns of intelligence differ from human-like behaviour, but it represents a crucial initial step towards increasingly general intelligent systems.

The paradigm shift

GPT-4 challenges conventional assumptions about machine intelligence and showcases emergent behaviours and capabilities that are not easily discernible in terms of their sources and mechanisms. Its intelligence signals a paradigm shift in the field of computer science and beyond. Although GPT-4 is not perfect and still has room for improvement, it represents a remarkable technological leap.

The development of GPT-4, an early version of a large language model, demonstrates significant progress towards Artificial General Intelligence. Its broad range of capabilities, human-level performance on various tasks, and the paradigm shift it signifies are crucial advancements in the field of AI. While GPT-4 has limitations and biases, its emergence highlights the potential for future, increasingly intelligent systems. Further research and exploration will be necessary to unlock the full potential of artificial intelligence.

The researchers warns that the capabilities of GPT-4 will shift perceptions on tasks that require human effort, potentially leading to the displacement of jobs and broader economic influences. Other implications of the new powers include the enablement of malevolent actors with new tools of disinformation and manipulation. On limitations, deficits in the reliability of the system and in the biases that it learns, can lead to problems given potential over-reliance and poor understanding about when the system fails or will demonstrate bias, potentially amplifying existing societal issues.

ChatGPT mystifies its creators

Interestingly enough the researchers admit that they do not fully understand how ChatGPT is reasoning, planning and creating. The paper states:” we have focused on the surprising things that GPT-4 can do, but we do not address the fundamental questions of why and how it achieves such remarkable intelligence. How does it reason, plan, and create? Why does it exhibit such general and flexible intelligence when it is at its core merely the combination of simple algorithmic components—gradient descent and large-scale transformers with extremely large amounts of data? These questions are part of the mystery and fascination of LLMs, which challenge our understanding of learning and cognition, fuel our curiosity, and motivate deeper research.”
