OpenAI's GPT-5.4 powers AI chemist in robotic lab, boosting reaction yields

OpenAI and Molecule.one collaborated to integrate an AI chemist, powered by GPT-5.4, with a robotic laboratory system. This setup successfully executed 10,080 chemical reactions over three months, focusing on a challenging medicinal chemistry step. The AI's key recommendation to add TEMPO resulted in a significant yield increase, and human verification confirmed the improvements across multiple substrate pairs. AI

IMPACT Demonstrates AI's potential to accelerate drug discovery and chemical synthesis through automated experimentation and optimization.

RANK_REASON This is a demonstration of an AI model integrated into a specific workflow, rather than a new model release or core research.
