Researchers have developed MolHop, a novel agentic framework designed for molecular discovery that moves beyond simple optimization to identify structurally distinct molecules with preserved functional characteristics. By organizing millions of molecular scaffolds into a hierarchical action space, MolHop enables AI agents to navigate and edit chemical structures, maintaining historical memory for complex search processes. When integrated with models like Grok-4.6 and DeepSeek-Flash-V4.1, MolHop significantly boosts cross-scaffold discovery success rates. Furthermore, a MolHop-9B model trained via agentic reinforcement learning has demonstrated superior performance compared to leading generative models such as GPT-5.6-sol, Claude-5-Opus, and Gemini-3.1-Pro, by generating molecules with greater scaffold diversity.
