The Token Games: Evaluating Language Model Reasoning with Puzzle Duels

In a research lab somewhere between theory and application, The researchers have been quietly working on a problem that has stumped the AI community for years. This week, they published results that could fundamentally change how we think about machine learning.

Inside the Breakthrough

arXiv:2602.17831v1 Announce Type: new
Abstract: Evaluating the reasoning capabilities of Large Language Models is increasingly challenging as models improve. Human curation of hard questions is highly expensive, especially in recent benchmarks using PhD-level domain knowledge to challenge the most capable models. Even then, there is always a concern about whether these questions test genuine reasoning or if similar problems have been seen during training. Here, we take inspiration from 16th-century mathematical duels to design The Token Games (TTG): an evaluation framework where models challenge each other by creating their own puzzles. We leverage the format of Programming Puzzles – given a Python function that returns a boolean, find inputs that make it return True – to flexibly represent problems and enable verifying solutions. Using results from pairwise duels, we then compute Elo ratings, allowing us to compare models relative to each other. We evaluate 10 frontier models on TTG, and closely match the ranking from existing benchmarks such as Humanity’s Last Exam, without involving any human effort in creating puzzles. We also find that creating good puzzles is still a highly challenging task for current models, not measured by previous benchmarks. Overall, our work suggests new paradigms for evaluating reasoning that cannot be saturated by design, and that allow testing models for other skills like creativity and task creation alongside problem solving.

The development comes at a pivotal moment for the AI industry. Companies across the sector are racing to differentiate their offerings while navigating an increasingly complex regulatory environment. For The, this move represents both an opportunity and a challenge.

From Lab to Real World

Market positioning has become increasingly critical as the AI sector matures. The is clearly signaling its intent to compete at the highest level, investing resources in capabilities that could define the next phase of the industry’s evolution.

Competitive dynamics are also shifting. Rivals will likely need to respond with their own announcements, potentially triggering a wave of activity across the sector. The question isn’t whether others will follow—it’s how quickly and at what scale.

Enterprise adoption remains the ultimate test. As organizations move beyond experimental phases to production deployments, they’re demanding concrete returns on AI investments. The’s latest move appears designed to address exactly that demand.

“We’re past the hype cycle now. Companies that can demonstrate real value—measurable, repeatable, scalable value—are the ones that will define the next decade of AI.” — Venture Capital Partner

What Comes Next

Industry observers are watching closely to see how this strategy plays out. Several key questions remain unanswered: How will competitors respond? What does this mean for pricing and accessibility in the research space? Will this accelerate enterprise adoption?

The coming months will reveal whether The can deliver on its promises. In a market where announcements often outpace execution, the real test will be what happens after the initial buzz fades.

For now, one thing is clear: The has made its move. The rest of the industry is watching to see what happens next.
