Coscientist: AI-Powered System Designs and Executes Chemical Reactions in Robotic Labs

Researchers at Carnegie Mellon University, led by chemist Gabe Gomes, have harnessed the power of artificial intelligence (AI), specifically the GPT-4 language model, to develop an innovative system called Coscientist. The AI-driven system can autonomously design, code, and execute complex chemical reactions using a robotic laboratory setup.

The breakthrough comes as a response to the challenge of making AI tools more accessible to bench researchers and those less familiar with computer coding. Gomes and his team adapted the latest large language model (LLM) version behind ChatGPT, leveraging GPT-4’s capabilities. Coscientists utilize GPT-4 and other powerful LLMs such as Claude and Falcon-40B-Instruct to scour chemical literature, design reaction pathways, and ultimately synthesize molecules in a physical laboratory.

In a series of successful experiments, Coscientist demonstrated its proficiency by planning the synthesis of known molecules, including paracetamol, aspirin, nitroaniline, and phenolphthalein. The system effectively determined optimal reaction steps to achieve the highest overall yields. Notably, Coscientist excelled in a more complex task—executing the Suzuki–Miyaura coupling reaction, a process crucial in drug discovery that forms carbon–carbon bonds.

The development of AI-driven ‘chemistry robots’ like Coscientist is part of a broader trend in the scientific community. Another notable example, ChemCrow, was developed around the same time and can plan and produce various molecules, including the insecticide DEET.

Experts, including pharmaceutical chemist Tiago Rodrigues from the University of Lisbon, foresee the integration of AI assistants into automation hardware, leading to the emergence of self-driving labs. While these AI systems can now handle routine tasks, Gomes emphasizes the importance of acknowledging the limits of such technology, especially in addressing complex research questions in fields like drug discovery, where a deep understanding of chemistry and biology is essential.

Gomes expresses a cautious approach to deploying technologies like Coscientist and ChemCrow, highlighting the need to consider their applications carefully due to potential risks. He emphasizes that these AI systems are not meant to replace human ingenuity, innovation, and the vital contributions of skilled researchers.
