ORGANIC CHEMISTRY
Chemical synthesis is critical across life sciences, materials, and energy, yet conventional experimentation remains labor‑intensive. This work introduces Chemma, a fully fine‑tuned large language model trained on 1.28 million Q&A pairs about chemical reactions. Chemma surpasses existing benchmarks in tasks such as single‑step retrosynthesis and yield prediction, demonstrating that general AI can match expert-level understanding without quantum‑chemical data. By integrating Chemma within a Bayesian optimization and active‑learning loop, the authors achieved autonomous reaction planning: a novel Suzuki–Miyaura cross‑coupling was optimized within just 15 experimental runs, yielding 67% of the target product. This study highlights how tailored LLMs can not only predict but also accelerate experimental exploration in organic chemistry.
