Scientists at the Center for AI Safety and Scale AI have actually released “Humanity’s Last Exam” — a test created to determine how close today’s most effective expert system (AI )designs are to conference or surpassing human-level understanding throughout a number of domains.
The test was released in January 2025, however researchers detailed the structure and their thinking behind its style for the very first time in a brand-new research study released Jan. 28 in the journal NatureIt consists of a corpus of 2,500 concerns throughout more than 100 topics, with input from more than 1,000 subject-matter professionals from 500 organizations throughout 50 nations.
At launch, the scientists checked OpenAI’s GPT-4o and o1 designs, Google’s Gemini 1.5 Pro, Anthropic’s Claude 3.5 Sonnet and DeepSeek R1. OpenAI’s o1 system notched the leading area with a rating of simply 8.3%.
Regardless of this bad efficiency, the scientists composed at the time that “given the rapid pace of AI development, it is plausible that models could exceed 50% accuracy on HLE by the end of 2025.”
Since Feb. 12, 2026, the greatest rating attained up until now is 48.4%, set by Google’s Gemini 3 Deep Think. Human specialists, on the other hand, score around 90% in their particular domains.
Checking the most intelligent devices on the planetMankind’s Last Exam was purposefully developed to be incredibly challenging for AI designs. Throughout early advancement, the scientists put out an international require submissions from subject professionals throughout many domains.

The scientists implemented rigorous submission requirements needing concerns to be accurate, unambiguous, understandable and non-searchable. They didn’t desire designs to cheat by carrying out a basic web search, or for any of the concerns to currently appear online– hence increasing the probability an offered design would have the response in its training dataset.
Each concern sent was then fed to the AI designs. The group instantly declined any concerns the designs might address properly.
More than 70,000 submissions were tried, leading to roughly 13,000 concerns that puzzled LLMs. These were then vetted by a group of subject specialists, authorized by the research study group, and provided to the clinical neighborhood for open feedback.
Eventually, the scientists narrowed the overall submissions to 2,500 concerns that usually fall within the world of PhD-level screening.
An example of a trivia question in the examination is: “In Greek folklore, who was Jason’s maternal great-grandfather?”
An example of a physics concern asks for the relationship in between various forces throughout movement in a situation where a block is put on a horizontal rail (and can move frictionlessly) while likewise being connected to a stiff, massless rod of an unidentified length.
The breadth of concerns and scope of topics covered by Humanity’s Last Exam sets it apart from comparable benchmarking tools, its developers state.
Typical tests, such as the Huge Multitask Language Understanding (MMLU) dataset, which was authored with involvement from Center for AI Safety creator Dan Hendrycksjust check a little subset of expert-level domain understanding, mainly concentrating on coding and mathematics.
Even advanced criteria such as Francois Chollet’s ARC-AGI suite battle to outmatch the memorization and searchability issues that the developers of Humanity’s Last Exam recommend the brand-new test addresses. Gemini’s Deep Think, for instance, accomplished 84.6% on the ARC-AGI-2 criteria, simply a week after stopping working to reach 50% on the HLE test.
The supreme reward is basic intelligenceHumankind’s Last Exam most likely represents the AI world’s finest effort to date at determining the broad-spectrum abilities of contemporary AI designs relative to human professionals, however the research study’s authors unconditionally specify that attaining a high rating on the HLE remains in no chance a sign of the arrival of synthetic basic intelligence (AGI).
“High accuracy on HLE would demonstrate expert-level performance on closed-ended, verifiable questions and cutting-edge scientific knowledge, but it would not alone suggest autonomous research capabilities or artificial general intelligence,” the scientists said in the study.
“Succeeding on HLE is a required, however not an adequate requirement to state that devices have actually reached real intelligence,” Manuel Schottdorf, a neuroscientist at the University of Delaware’s Department of Psychological and Brain Sciences, said in a recent statement. Schottdorf is one of the many experts whose question was accepted into the HLE’s corpus.
“They will need to suffice to fix these concerns, however that as a truth alone can’t permit us to conclude that devices are really smart.”
