# MolEditAgent-{3B}
**MolEditAgent** is the Stage-1 model of the **MolAct** framework. It is fine-tuned to master basic molecular editing primitives within an agentic loop.
### Key Features
- **Actionable Operations:** Learns to perform `Add`, `Delete`, and `Substitute` operations on SMILES.
- **Tool-Augmented:** Trained to interact with chemical tools for validity checking and similarity control.
- **Agentic Reasoning:** Unlike static generators, it can "Think" and "Call" tools to refine the editing process.
### Training & Usage
This model serves as the foundation for property-driven optimization.
