Science has always relied on a curious human’s mind forming a hypothesis, designing an experiment, analyzing the results and presenting the case to that person’s peers. Over centuries, we’ve built better tools such as electron microscopes, particle accelerators and supercomputers, but the core loop of scientific discovery has remained stubbornly human. Now, for the first time, that loop has started with a new kind of mind.
So far, scientists have often had artificial intelligence help them with solving a predefined, narrow task such as folding proteins, says Jeff Clune, a professor of computer science at the University of British Columbia. “We’re saying the AI gets to be the scientist,” he says.
In a recent Nature study, Clune and his colleagues unveiled the AI Scientist, an AI system that wrote a paper without human involvement that passed peer review for a workshop at the 2025 International Conference on Learning Representations (ICLR), a top-tier venue in the field of machine learning. The paper was mediocre, according to Clune and other experts. But its existence marks a turning point that the scientific community is only beginning to grapple with: AI has quickly moved from assisting scientists to attempting to be one.

The AI Scientist comprises multiple modules. After it is given a general topic prompt by researchers, it surveys available literature and generates hypotheses. “We’re just giving it a general direction like ‘Come up with something interesting to study on how the AI learns,’” Clune explains. The system then evaluates and refines those ideas, filtering out any that are not novel. From there, further modules plan and execute experiments, analyze and plot the…
