As artificial intelligence has advanced over the years, the methods used to measure its capabilities have become outdated. Tests that once challenged advanced AI models are now being solved with ease, making it harder for researchers to pinpoint what current systems are actually capable of.
However, an international team of researchers has recently developed a new exam designed to test the limits of modern AI systems. Known as Humanity’s Last Exam (HLE), the assessment includes 2,500 expert-level questions spanning disciplines from mathematics and natural sciences to ancient languages and humanities. Details of the project and its results are outlined in a recent study published in Nature.
Initial results indicate that even the most advanced AI models struggled with this exam. GPT-4o scored 2.7%, Claude 3.5 Sonnet 4.1%, and OpenAI’s o1 model reached about 8% accuracy. More recent systems, such as Gemini 3.1 Pro and Claude Opus 4.6, improved to around 40-50% accuracy.
When AI Outgrows Tests
For years, researchers have used standardized tests to track AI capabilities. One well-known example is the Massive Multitask Language Understanding (MMLU) exam, which tests models in many academic subjects.
Today, many advanced AI systems perform well on these exams, prompting questions about whether these tests still provide meaningful insights into the true capabilities of artificial intelligence.
“When AI systems start performing extremely well on human benchmarks, it’s tempting to think they’re approaching human-level understanding,” said Dr. Tung Nguyen, an instructional associate professor of computer science and engineering at Texas A&M University and a contributor to the new benchmark. “But HLE reminds us that intelligence isn’t just about pattern recognition — it’s about depth, context and specialized expertise.”
