AI-powered scientists under development faced obstacles: Updates on the progress of creating self-governing scientists using AI technology and the challenges encountered in the process.
In a groundbreaking development, researchers at The University of Tokyo have demonstrated that AI can autonomously carry out end-to-end scientific research workflows, including hypothesis generation and experimental design. The team's AI system, using the advanced language model GPT-4, successfully produced a peer-reviewed paper accepted at ICLR 2025, without any human intervention [1].
This achievement marks a significant milestone in AI's evolution, challenging the assumption that scientific creativity and intuition are uniquely human attributes. However, it also highlights the current boundaries of AI as autonomous scientific researchers [1].
The AI's scientific contributions so far tend to be incremental rather than groundbreaking. For instance, the hypothesis tested by the Tokyo system ultimately failed, indicating that AI still struggles with true scientific intuition akin to inventing novel fields [1]. The system's autonomy is impressive but may not yet fully replicate human-level insight or creativity, often depending on existing data and prior knowledge.
Philosophical and ethical challenges remain unresolved, including questions about AI free will, moral responsibility, and appropriate governance of autonomous AI in research contexts [1]. From a technical perspective, embodied AI systems face real-time latency and operational challenges, such as sequential processing bottlenecks and communication delays that limit the speed and applicability of AI in dynamic real-world scientific settings [2].
AI evaluation benchmarks might not perfectly reflect the complexity of scientific reasoning required for autonomous research, highlighting the difficulty of measuring AI's research capabilities accurately [3]. Human oversight is still widely regarded as necessary to ensure accountability, reliability, and ethical use of AI in research, suggesting that fully autonomous AI scientists must be carefully integrated within human-guided frameworks [4].
Despite these challenges, the study presents promising avenues for future progress. Testing language models on scientific problems requiring real formalization, data, and modeling is necessary for continued advancement. The researchers evaluated GPT-4's success at each stage of hypothesis generation and verification without any human intervention.
Across 50 trials, GPT-4 produced hypotheses deemed reasonable for the presented problem in 46 out of 50 trials. However, major gaps in autonomously translating high-level designs into concrete implementations were observed. Only 13 out of 50 trials successfully produced valid code to implement the designed experiment and analyze results [1].
Developing techniques to translate high-level plans into code and handle complex programming tasks is crucial. Improving hypothesis generation to produce more varied, creative, and original ideas is essential. The majority of trials yielded verification plans considered suitable, free of major errors, and proposing experiments relevant to the hypothesis.
The University of Tokyo researchers tested whether the powerful language model GPT-4 could generate novel hypotheses and verify them for a simplified research problem with minimal human guidance. The study underscores the importance of continued research and development in this exciting field, as we strive to unlock the full potential of AI as autonomous scientific researchers.

The significant milestone achieved by the AI system at The University of Tokyo, using technology like GPT-4, shows that artificial-intelligence can generate hypotheses and design experiments autonomously, challenging the assumption that scientific creativity is uniquely human.
