In a groundbreaking speech at MIT, Hyung Won Chung, chief scientist of OpenAI and a key member of the OpenAI o1 model team, proposed a revolutionary concept in AI training: “don’t teach, but motivate.” This paradigm shift in approach could be the key to unlocking Artificial General Intelligence (AGI), a long-sought goal in the field of artificial intelligence.

The Limitations of Traditional AI Training

Traditional methods of AI training involve teaching models specific tasks one by one. However, as the complexity and scale of AI applications grow, this approach becomes increasingly inefficient and impractical. Chung argues that this method is not suitable for developing the broad, adaptable intelligence required for AGI.

The Power of Motivation in AI Learning

Instead of direct instruction, Chung advocates for the use of incentive structures to promote spontaneous learning in AI models. He likens this approach to the age-old wisdom of teaching a man to fish:

“It is better to teach a man how to fish than to give him a fish”, but the further motivation should be: “Let him know that fish is delicious and keep him hungry.”

This analogy illustrates the power of motivation in learning. By creating an environment where the AI is motivated to learn, it will not only acquire the specific skill (fishing) but also develop a range of related and generalizable skills (patience, weather reading, understanding fish behavior).

The Role of Computation in AI Learning

While this approach may seem time-consuming for human learners, Chung points out a crucial difference for machines: the ability to accelerate learning through increased computational power. As computing resources continue to grow exponentially, AI systems can overcome human time constraints and potentially outperform experts in specialized fields.

Chung draws a parallel to the “Hyperbolic Time Chamber” in Dragon Ball, where characters can experience a year of training in just a day. For AI, this multiplication factor is even more dramatic, allowing for rapid skill acquisition and refinement.

The Exponential Growth of Computing Power

One of the most critical factors enabling this approach is the exponential growth in computing power. Chung presented data showing that computing power has been doubling approximately every two years, while costs have been decreasing at a similar rate. This trend provides unprecedented opportunities for AI research and development.

Weak Incentive Learning: The Path to General Intelligence

Current large-scale language models like GPT-3 and GPT-4 utilize weak incentive learning, primarily through next-word prediction tasks. Chung argues that this simple task drives the model to develop a wide range of skills, including reasoning, mathematics, and coding, without explicit instruction in these areas.

This approach allows models to develop general problem-solving abilities autonomously when faced with a large number of diverse tasks. The key is to provide weak incentives that encourage the model to explore and learn, rather than prescribing specific outcomes.

Emergent Abilities: The Surprising Power of Scale

As models scale up in size and complexity, they often develop unexpected capabilities. These “emergent abilities” arise naturally during the training process, without being explicitly programmed. Chung cites examples from large language models that demonstrate complex reasoning and mathematical computation without specific training in these areas.

This phenomenon suggests that as AI models grow in scale and are exposed to more diverse data and tasks, they may spontaneously develop new, unforeseen capabilities. This emergent behavior is a crucial aspect of the path towards AGI.

Designing Better Incentive Structures

Chung advocates for the development of more sophisticated incentive structures to guide AI learning. By introducing richer reward mechanisms, models can be encouraged to develop higher-level capabilities. For example, to address the “hallucination problem” in language models, an incentive structure could be designed to reward the model for accurately assessing its own knowledge and admitting uncertainty when appropriate.

These more complex incentive structures could help models develop meta-cognitive abilities, improving their reliability and versatility across a wide range of tasks.

Rethinking Scalability in AI

Chung challenges the traditional definition of scaling in AI, which often focuses solely on increasing computational resources. He proposes a more nuanced view:

Scaling should involve identifying and replacing assumptions or structures that limit further growth with more scalable methods.

This perspective emphasizes the importance of continually reassessing and redesigning AI architectures to better leverage increasing computational power and data availability.

The Need for Continuous Learning in AI Research

As AI capabilities rapidly evolve, researchers must be prepared to continuously update their understanding and approaches. Chung stresses the importance of adaptability in the face of new models and paradigms:

The development of language models requires us to abandon old cognitions and adapt to the new capabilities brought by new models almost every few years.

This adaptability is crucial for staying at the forefront of AI research and development.

The Future of AGI Development

Chung’s vision for the future of AGI development centers on several key principles:

Leveraging exponentially growing computational resources
Designing scalable algorithms that can take advantage of this trend
Utilizing weak incentive structures to drive the development of general skills
Embracing and studying emergent capabilities as models scale
Continuously adapting to new technological developments and model capabilities

By following these principles, Chung believes that the AI community can make significant strides towards achieving true Artificial General Intelligence.
