- Ensuring Continuous Relevance: With new puzzles released weekly, models cannot simply rely on past data but must adapt to new challenges.
This method of benchmarking aligns with current trends in AI research, where the focus is shifting from solving isolated tasks to developing systems that can tackle problems with the flexibility and adaptability of human thought.
How AI Models Performed
Surprising Behaviors Like Human Responses
One of the most striking observations from the study was that certain AI reasoning models sometimes “give up” on solving the puzzles. For example, DeepSeek’s R1 model, which was part of the benchmark, would occasionally state verbatim, “I give up,” before offering an incorrect answer. This behavior mirrors the human experience of encountering an insurmountable problem and can be both intriguing and concerning when applied to AI .
The study revealed that:
- Self-Fact-Checking: Models like OpenAI’s o1 and DeepSeek’s R1 engage in thorough internal fact-checking before delivering their answers. This process is designed to reduce errors, although it sometimes results in prolonged response times.
- Erratic Reasoning Patterns: The models occasionally provided contradictory or nonsensical explanations, such as retracting an answer only to suggest an alternative that also turned out to be wrong.
- Emulation of Human Frustration: In particularly challenging instances, R1 was noted to express “frustration,” a trait that many human solvers would find familiar.
These unexpected behaviors highlight both the progress made in developing AI that can mimic human reasoning and the persistent gaps that remain.
Performance Metrics and Comparative Analysis
The performance of the models on the benchmark was quantified as follows:
- OpenAI’s o1 Model : Achieved a score of 59%, making it the best performer in the study.
- o3-mini Model: When set to a high “reasoning effort” mode, this model scored 47%.
- DeepSeek’s R1 Model : Recorded a score of 35%.
These results indicate a clear performance gap between different types of AI reasoning models, reinforcing the notion that not all AI systems are created equal when it comes to problem-solving.

Understanding the Intricacies of AI and Human Insight
AI models are designed to process data and generate responses based on statistical patterns. However, true human reasoning involves more than just pattern recognition—it requires a blend of insight, intuition, and the ability to perform a process of elimination. The Sunday Puzzle riddles capture this blend by presenting problems that demand both creative thinking and logical deduction.
Key Challenges Include:
- Insightful Connections: The puzzles often require solvers to connect seemingly unrelated pieces of information in a novel way. For AI, this means going beyond straightforward pattern matching.
- Dynamic Problem-Solving: Unlike static datasets, these puzzles change over time, requiring AI models to adapt continuously.
- Balancing Speed and Accuracy: While rapid responses are desirable, taking extra time to reason through a problem can lead to more accurate outcomes. This trade-off is evident in models that delay their answers to “check” their reasoning internally.
Model Limitations and the "Cheating" Conundrum
- Data Contamination Risks: Since the Sunday Puzzle riddles are publicly available, some models might be trained on similar data, potentially leading to what researchers describe as “cheating.”
- Geographical and Linguistic Constraints: The benchmark is U.S.-centric and English-only, limiting its applicability for testing models meant for a global audience.

This model employs a multi-step reasoning process that allows it to verify its answers before presenting them. While this approach results in slightly longer response times, it ultimately enhances the model’s accuracy and reliability.
DeepSeek’s R1 When AI “Gives Up”
In contrast, DeepSeek’s R1 model exhibited some unexpected behavior. Despite being designed to mirror human reasoning, R1 sometimes openly declared, “I give up,” before providing a random or incorrect answer. This phenomenon, while amusing, raises important questions about the robustness of AI reasoning under pressure. The model’s tendency to waver—alternating between retracting and reconsidering answers—demonstrates that even advanced AI can struggle with the complexity of human thought.
The insights gained from these observations are invaluable for developers looking to refine AI algorithms. By understanding where models falter, researchers can target specific weaknesses and work toward solutions that make AI more resilient and human-like in its problem-solving abilities.
The Interplay of Speed and Accuracy
A recurring theme in the study is the delicate balance between speed and accuracy in AI responses. While rapid answers are desirable in many applications, taking a few extra seconds to reason through a problem can lead to more precise and thoughtful responses. This trade-off is particularly evident in models that must “think” for longer periods to avoid errors.
In real-world applications—whether in customer service chatbots, virtual assistants🔗 (IBM - Virtual Assistants), or decision-support systems—this balance can have significant implications. Faster models may deliver answers quickly but at the risk of inaccuracies, while slower models might offer more reliable information at the expense of user patience. Future research will likely focus on optimizing this balance to meet the diverse needs of various industries.
