AI benchmarks have long been the standard for measuring progress in artificial intelligence. They offer a tangible way to evaluate and compare system capabilities. But is this approach the best way to assess AI systems? Andrej Karpathy recently raised concerns about the adequacy of this approach in a post on X. AI systems are becoming increasingly skilled at solving predefined problems, yet their broader utility and adaptability remain uncertain. This raises an important question: Are we holding back AI’s true potential by focusing only on puzzle-solving benchmarks??
Personally I don’t know about little benchmarks with puzzles it feels like atari all over again. The benchmark I’d look for is closer to something like sum ARR over AI products, not sure if there’s a simpler / public that captures most of it. I know the joke is it’s NVDA

LLM benchmarks like MMLU and GLUE have undoubtedly driven remarkable advancements in NLP and Deep Learning. However, these benchmarks often reduce complex, real-world challenges into well-defined puzzles with clear goals and evaluation criteria. While this simplification is practical for research, it may hide deeper capabilities needed for LLMs to impact society meaningfully.
Karpathy’s post highlighted a fundamental issue: “Benchmarks are becoming increasingly like solving puzzles.” The responses to his observation reveal widespread agreement within the AI community. Many commenters emphasized that the ability to generalize and adapt to new, undefined tasks is far more important than excelling in narrowly defined benchmarks.

Overfitting to Metrics
AI systems are optimized to perform well on specific datasets or tasks, leading to overfitting. Even when benchmark datasets are not explicitly used in training, leaks can occur, causing the model to inadvertently learn benchmark-specific patterns. This hinders its performance in broader, real-world applications.AI systems are optimized to perform well on specific datasets or tasks, leading to overfitting. This does not necessarily translate to real-world utility.
Lack of Generalization
Solving a benchmark task does not guarantee that the AI can handle similar, slightly different problems. For example, a system trained to caption images might struggle with nuanced descriptions outside its training data.
Narrow Task Definitions
Benchmarks often focus on tasks like classification, translation, or summarization. These do not test broader competencies like reasoning, creativity, or ethical decision-making.
The limitations of puzzle-solving benchmarks call for a shift in how we evaluate AI. Below are some suggested approaches to redefine AI benchmarking:
Instead of static datasets, benchmarks could involve dynamic, real-world environments where AI systems must adapt to changing conditions. For instance, Google is already working on this with initiatives like Genie 2, a large-scale foundation world model. More details can be found in their DeepMind blog and Analytics Vidhya’s article.
Benchmarks should test AI’s ability to perform tasks requiring long-term planning and reasoning. For example:
As AI systems increasingly interact with humans, benchmarks must measure ethical reasoning and social understanding. This includes incorporating safety measures and regulatory guardrails to ensure responsible use of AI systems. The recent Red-teaming Evaluation provides a comprehensive framework for testing AI safety and trustworthiness in sensitive applications. Benchmarks must also ensure AI systems make fair, unbiased decisions in scenarios involving sensitive data and explain their decisions transparently to non-experts. Implementing safety measures and regulatory guardrails can mitigate risks while fostering trust in AI applications. to non-experts.
Benchmarks should test an AI’s ability to generalize across multiple, unrelated tasks. For instance, a single AI system performing well in language understanding, image recognition, and robotics without specialized fine-tuning for each domain.
As the AI field evolves, so must its benchmarks. Moving beyond puzzle-solving will require collaboration between researchers, practitioners, and policymakers to design benchmarks that align with real-world needs and values. These benchmarks should emphasize:
Karpathy’s observation challenges us to rethink the purpose and design of AI benchmarks. While puzzle-solving benchmarks have driven incredible progress, they may now be holding us back from achieving broader, more impactful AI systems. The AI community must pivot toward benchmarks that test adaptability, generalization, and real-world utility to unlock AI’s true potential.
The path forward will not be easy, but the reward – AI systems that are not only powerful but also genuinely transformative – is well worth the effort.
