MolOptAgent-3B

MolOptAgent-{3B/7B}

MolOptAgent is the Stage-2 model of the MolAct framework, continued training from MolEditAgent using Agentic Reinforcement Learning (GRPO).

Key Features

• Objective: Optimized for multi-step molecular property optimization (e.g., LogP, Solubility, QED, Bioactivity).
• Zero-Tolerance for Errors: Guided by real-time tool feedback, it minimizes "Chemical Hallucinations" and ensures nearly 100% molecular validity.
• Performance: Outperforms strong reasoning models like Claude-3.7 and DeepSeek-R1 in complex property-guided editing tasks.
