Sakana AI, in collaboration with scientists from the University of Oxford and the University of British Columbia, has developed an artificial intelligence system that can conduct end-to-end scientific research autonomously. This breakthrough, named “The AI Scientist,” promises to completely transform the process of scientific discovery.
The AI Scientist automates the entire research lifecycle, from generating novel ideas to writing full scientific manuscripts. “We propose and run a fully AI-driven system for automated scientific discovery, applied to machine learning research,” the team reports in their newly released paper.

It then determines how to test the hypotheses, including writing the necessary code by editing a codebase powered by recent advances in automated code generation. Afterward, the experiments are automatically executed to collect a set of results consisting of both numerical scores and visual summaries (e.g. plots or tables). The results are motivated, explained, and summarized in a LaTeX report. Finally, The AI Scientist generates an automated review, according to current practice at standard machine learning conferences. The review can be used to either improve the project or as feedback to future generations for open-ended scientific discovery. Source: arxiv.org/pdf/2408.06292

The implications of such a system are profound and multifaceted. On one hand, it could dramatically accelerate the pace of scientific discovery by allowing continuous, round-the-clock research without human limitations. This could lead to rapid advancements in fields like drug discovery, materials science, and climate change mitigation.
However, the automation of scientific research raises critical questions about the future role of human scientists. While AI may excel at processing vast amounts of data and identifying patterns, human intuition, creativity, and ethical judgment remain crucial in steering scientific inquiry towards meaningful and beneficial outcomes. The challenge will be in finding the right balance between AI-driven efficiency and human-guided purpose in scientific research.
…The AI Scientist has several significant limitations in its current form. The automated reviewer cannot ask authors questions and cannot interpret figures. Idea generation often produces very similar proposals across different runs and models. Implementation of ideas often fails or is implemented incorrectly. Due to the limited number of experiments, the results often lack the depth and accuracy typical in the ML community. The AI Scientist also struggles with visual aspects, such as illegible charts or suboptimal page layout.
Other weaknesses relate to citation practices and correct interpretation of results. The AI Scientist has difficulty finding and citing the most relevant sources. When evaluating results, critical errors occasionally occur, such as when comparing numerical values or considering changed metrics. In rare cases, entire results are even hallucinated. The authors therefore advise against taking the scientific content of the generated papers at face value. Instead, the papers should be viewed as suggestions for promising ideas that experts can pursue further.
