Closing the Prior-Posterior Loop: Self-Reflective Molecular Design with Analysis-Driven LLM Iteration
Researchers have developed a novel method for molecular design using large language models (LLMs) that moves beyond simple trial-and-error. By feeding detailed physicochemical rationales, such as orbital energies and atomic charges, back into the LLM instead of just numerical scores, the system acts as a causal reasoner. This self-reflective approach achieved a 100% success rate on moderate tasks for targeting HOMO-LUMO gaps and proved effective for dipole-moment design across multiple LLM backbones. AI
