Abstract
AGI has been a long-standing goal of humanity, with the aim of creating machines capable of performing any intellectual task that humans can do. To achieve this, AGI researchers draw inspiration from the human brain and seek to replicate its principles in intelligent machines. Brain-inspired artificial intelligence is a field that has emerged from this endeavor, combining insights from neuroscience, psychology, and computer science to develop more efficient and powerful AI systems. In this article, we provide a comprehensive overview of brain-inspired AI from the perspective of AGI. We begin with the current progress in brain-inspired AI and its extensive connection with AGI. We then cover the important characteristics for both human intelligence and AGI (e.g., scaling, multimodality, and reasoning). We discuss important technologies toward achieving AGI in current AI systems, such as in-context learning and prompt tuning. We also investigate the evolution of AGI systems from both algorithmic and infrastructural perspectives. Finally, we explore the limitations and future of AGI.

Introduction to Brain-Inspired AI
The human brain, a marvel of evolution, showcases incredible capabilities such as sensory data integration, parallel processing, and cognitive functions like decision-making and abstract reasoning. In the realm of AI, a field known as brain-inspired AI seeks to harness these attributes of human intelligence to create powerful AI systems. Such systems aim to mirror the efficiency and adaptability of the brain, making strides toward AGI – the ability of machines to perform any intellectual task that a human being can.
The Interplay Between Brain-inspired AI and AGI
Brain-inspired AI forms a pivotal aspect of advancing towards AGI. This convergence of neuroscience, psychology, and computer science has influenced various AI advancements, such as backpropagation, convolutional neural networks (CNNs), and attention mechanisms famously recognized in the "Transformer" model. These technologies have inherently drawn from understandings of how the brain processes information and adapts to its environment. Going further, evidence suggests that artificial and biological neural networks may share common principles in optimizing network architectures, potentially leading to more efficient AI models that closely emulate the brain's small-world network properties.
Technological Milestones Toward AGI
In pursuit of AGI, certain technologies play critical roles. Techniques like in-context learning and prompt tuning are essential, as they enable AI systems to swiftly learn and apply new tasks based on previously acquired knowledge. LLMs, through these methods, can generate coherent text and answer complex questions with impressive accuracy. Moreover, the advancement of multimodal AI, which can understand and process information across various types of data such as images, text, and audio, further aligns the capabilities of AI systems with the intricacies of human intelligence. These advancements are leading to AI that can not only execute tasks proficiently but also behave in an aligned manner with user intentions and human feedback.
Challenges and Prospects for AGI
Despite remarkable progress, achieving AGI presents challenges, such as our limited understanding of the human brain's complete workings, the ethical implications of intelligent machines, and ensuring safety and alignment with human values. Moreover, computational costs remain a constraint. Looking ahead, AGI development is likely to leverage sophisticated models, larger-scale datasets and computing resources, and novel machine learning approaches inspired by the human brain's efficient learning mechanisms.
Conclusion
The trajectory towards AGI is undeniably intertwined with brain-inspired AI. While AGI still embodies a frontier yet to be fully attained, its potential to transform various aspects of society is of paramount importance. Embracing the advances, addressing the challenges, and preparing for the ethical considerations of such intelligent systems will be crucial steps in harmonizing the growth of AI with the betterment of mankind.
