What problems do we need to solve to build an AI Scientist?

Building an AI Scientist requires addressing several complex challenges beyond current capabilities of large language models (LLMs). The process involves navigating open-ended scientific spaces, which includes generating diverse and novel hypotheses, conducting experiments, and updating hypotheses based on results. Effective hypothesis generation and experiment selection are crucial, as they must maximize information gain and account for the reliability of results. Additionally, integrating AI with experimental processes and ensuring robust engineering to access scientific literature and databases is essential. Evaluating the performance of AI systems in scientific tasks is another significant hurdle, necessitating scalable methods to assess accuracy and reliability. The development of environments that simulate scientific research and provide quality feedback for training AI agents is also critical. Overall, creating a functional AI Scientist will require substantial engineering efforts, innovative approaches to reinforcement learning, and a long-term commitment to overcoming these challenges. While advancements may not be immediate, the potential impact of a successful AI Scientist could be transformative for scientific discovery.

I run FutureHouse, a non-profit AI-for-Science research lab in San Francisco focused on automating research in biology and other complex sciences. Several people asked me to respond to Sakana's AI Scientist release earlier in the week, but based on comments here and elsewhere I think people mostly get it: it's chatGPT or Claude writing code, making some plots, and then writing papers. It's a nice demo, but not a major technical breakthrough. So, instead, I took the opportunity to write up some thoughts on the big problems we need to solve to build a real AI scientist. Enjoy...

Nice article. I have some questions:

Do you think an AI scientist would be a set of decentralized models, or a big foundation model that only a few companies can make, like we see with LLMs?

To what extent will an AI science replace human scientists or change their job description?

My personal thoughts: unlike language, science doesn't have a big central dataset we can train everything on. Simulating physics and interfacing with a wet lab are fundamentally different. It seems to me like science might involve more, smaller models compared to LLMs. It's likely that LLMs themselves and other large models will also play a part.

First of all, you need to be very experienced at building real scientists.

All others need not apply.
