Scaling and the Road to Human-Level AI | Anthropic Co-founder Jared Kaplan

Summary

Anthropic co-founder Jared Kaplan explains how predictable scaling laws in pre-training and reinforcement learning are driving rapid advancements in AI, enabling models like Claude 4 to perform increasingly complex and long-horizon tasks. He outlines the additional components needed for human-level AI and advises builders to focus on applications that push current AI capabilities.

Key Points

• Jared Kaplan's background as a theoretical physicist influenced his approach to AI research, leading him to identify and precisely quantify the fundamental scaling laws that govern AI performance.
• Contemporary AI model training primarily consists of two phases: pre-training, where models learn correlations and predict text in vast datasets, and reinforcement learning, which fine-tunes models to exhibit helpful, honest, and harmless behaviors based on human feedback.
• Empirical scaling laws demonstrate that AI performance predictably improves with increases in compute power, dataset size, and neural network scale, providing a strong basis for anticipating continued advancements.
• AI capabilities are evolving along two dimensions: increased flexibility to handle multiple modalities (like text and images) and an extended time horizon for tasks, with the length of tasks AI can accomplish doubling approximately every seven months.
• Achieving human-level AI broadly construed requires integrating organizational knowledge, developing robust memory for tracking long-duration tasks, and improving oversight mechanisms for handling nuanced, "fuzzy" problems where correctness is not always clear-cut.
• Anthropic's Claude 4 model showcases progress in agentic behavior, particularly for coding, by being less "eager" and improving adherence to specific instructions, alongside enhanced capabilities for saving and retrieving memories across extended tasks.
• AI's intelligence profile differs from humans, being capable of brilliant feats but also basic errors, which implies that humans will increasingly serve as "managers" to sanity-check and guide AI work rather than performing tasks themselves.
• The increasing capability of AI models allows companies to transition from selling "co-pilot" tools to offering solutions that replace entire human workloads, especially in domains where a high but not necessarily perfect success rate is acceptable.
• Despite the significant compute required, the current focus in AI development is on unlocking frontier capabilities, but over time, efforts to optimize algorithms and hardware will dramatically reduce the cost of AI inference and training.
• Kaplan views deviations from observed scaling laws as indicators of problems within the AI training process—such as architectural flaws or bottlenecks—rather than a fundamental breakdown of the scaling principle itself.
• AI's extensive "breadth of knowledge" gained during pre-training enables it to synthesize information and generate insights by connecting disparate fields, which can lead to novel discoveries that might elude individual human experts.

Conclusion

The consistent nature of AI scaling laws suggests an ongoing, rapid progression toward more advanced, general-purpose AI, emphasizing the need for continuous innovation in AI development.

Entrepreneurs and builders should anticipate and proactively develop products for tasks that AI models are not yet capable of, leveraging the expectation that future models will unlock those possibilities.

The evolving human-AI collaboration paradigm will increasingly position humans as strategic orchestrators and validators of AI-generated work, particularly for complex and nuanced tasks.

Discussion Topics

• As AI models become increasingly capable of independent task execution, what specific, complex human endeavors are most ripe for full AI automation in the next 1-3 years?
• Considering AI's increasing "breadth of knowledge," how can cross-disciplinary teams best leverage AI to unlock novel insights that might be impossible for human experts alone?
• If scaling laws continue to hold, what innovative approaches can startups take to build products that anticipate future AI capabilities, rather than being limited by current model performance?

Key Terms

Pre-training

The initial phase of training large language models where they learn statistical relationships and patterns by predicting subsequent elements in vast datasets of text and multimodal information.

Reinforcement Learning (RL)

A machine learning method used to fine-tune AI models by rewarding desired behaviors and discouraging undesirable ones, typically based on human feedback or defined objectives.

Scaling Laws

Empirical relationships observed in AI that show a predictable and consistent improvement in model performance as computational resources, such as data, model size, and compute, are increased.

ELO Score

A rating system, originally developed for chess, used to estimate the relative skill levels of players or, in AI, to benchmark models based on human preferences for their outputs.

Multimodal data

Data that combines information from multiple distinct modalities, such as text, images, and audio, allowing AI models to process and understand diverse forms of input.

Context Window

The maximum amount of input text or data that a large language model can process and consider at one time during a conversation or task.

FP2 / FP4

Refers to floating-point precision formats (2-bit or 4-bit) used in computing, where fewer bits can lead to faster calculations and lower memory usage but potentially reduced accuracy.

Jevons Paradox

An economic principle suggesting that as technological efficiency in resource use increases, the total consumption of that resource may rise due to increased demand or new applications.

AGI

Artificial General Intelligence, a hypothetical form of AI capable of understanding, learning, and applying intelligence to a wide range of tasks at a level comparable to or exceeding human cognitive abilities.
