Have you ever pondered how to unravel the fundamental patterns that characterize human thought processes?

The Abstraction and Reasoning Corpus (ARC) is a special benchmark created to gauge the development of AI skills and monitor advancements made toward human-level AI.
François Chollet, a Google software engineer and AI researcher, introduced it in 2019.

Current algorithms can only handle up to 31% of the entire ARC tasks, whereas humans can easily complete an average of 80% of them.

Why ARC?

The Abstraction and Reasoning Corpus (ARC) is a paradigm shift in the way we quantify artificial intelligence, not just a collection of puzzles. Because traditional AI systems are frequently trained on large datasets, they can excel at tasks they have seen before but have trouble with novel, unfamiliar issues.

ARC completely contradicts this notion. Instead of providing AI vast amounts of data, ARC pushes models to solve invisible problems with limited understanding, similar to how people can solve problems they have never faced before.

This is why it matters:

Assesses General Intelligence: ARC not only assesses memorization but also an AI’s capacity for reasoning, pattern recognition, and generalization — which are critical for intelligence comparable to that of humans.

Draws Attention to AI’s Weaknesses: Most sophisticated AI models, such as state-of-the-art neural networks, still have trouble with ARC tasks. This demonstrates that although they excel in certain domains, they do not have the same capacity for adaptive reasoning as people.

Promotes AGI Research: ARC is viewed as a precursor to artificial general intelligence (AGI), or AI that has humanoid abilities for learning, thinking, and adapting. Gaining proficiency in ARC would bring us one step closer to building machines with true intelligence.

Real-World Implications: Robotics, automation, choices, and other fields where systems have to be able to think creatively and adapt to unforeseen obstacles may be significantly impacted if AI is able to solve ARC-style problems.

The ARC-AGI-1 task data is available in this repository, along with a browser-based interface that allows users to attempt manual task solving.

How Does ARC Function?

An AI system’s ability to understand patterns and apply reasoning without relying on vast amounts of data is tested using the Abstraction and Reasoning Corpus (ARC).

However, how does it accomplish this?

Each of the puzzles that ARC offers consists of a few input-output examples.

In theory, the task is straightforward:

• Identify the pattern that links the examples of input and output.
• Adapt that pattern to a new input and generate the appropriate output.

These puzzles are based on visual grids, which frequently have spatial arrangements, colors, and shapes.

For instance:

A collection of colored squares is displayed in a grid. The AI must determine the rule (such as change blue to red or mirror the image horizontally) and apply it to a new grid. Moving shapes or adding components in accordance with a secret pattern could be the subject of another puzzle.

Grids ranging in size from a minimum of 1×1 to a maximum of 30×30 comprise each task. Each of the nine numbers that fill the grid’s cells is represented by a different color, for a total of ten distinct colors.

Only when the grid’s size and each cell’s color exactly match the expected response is the output grid’s construction considered successful.

Challenges of ARC

Although the Abstraction and Reasoning Corpus (ARC) provides a solid way of assessing actual intelligence, it also poses considerable difficulties — particularly for AI models.

This explains why ARC is so difficult:

• The majority of AI systems, such as those in language processing and image recognition, are successful because they are trained on massive datasets that contain millions of identical examples.

On the other hand, ARC tasks are wholly new. The model must infer the logic behind every new puzzle; it cannot just memorize patterns.

• ARC puzzles usually only include a few examples (sometimes just 1-3). This is similar to how humans can learn from very little data, but AI, which frequently relies on big data for learning, finds this to be a huge challenge.

• Certain puzzles require several stages of reasoning, such as spotting a pattern, using it in various grid sections, and altering elements according to intricate rules. These actions necessitate abstract thinking, which is difficult for existing AI models to mimic.

• Many of the most advanced AI models are superb at certain tasks but cannot generalize to new kinds of issues. This limitation is brought to light by ARC, which demonstrates the extent of research that remains before AI can genuinely think similar to a human.

• Even the most advanced AI systems, such as deep learning-based ones, do poorly on ARC tasks. Even the most advanced models are baffled by certain problems that are clear to humans.

Conclusion: Decoding the Abstraction and Reasoning Corpus in 2025

The abstraction and reasoning corpus offers a unique window into how machines can learn abstract concepts and reasoning patterns.

Without the need for specialized knowledge, ARC tasks can be completed with just the fundamental knowledge that young children are born with or naturally acquire. In general, ARC is a test that anyone can take, regardless of background, such as a human, a Martian, or a machine from the fictional planet Metal.
