• 🧭 Includes implementations of common search algorithms
• 🧪 Includes wrappers for state-of-the-art reaction models
• ⚙️ Exposes a simple API to plug in custom models and algorithms
• 📈 Can be used to benchmark components of a retrosynthesis pipeline

Quick Start

To install syntheseus with all the extras, run

conda env create -f environment_full.yml
conda activate syntheseus-full

pip install "syntheseus[all]"

See here if you prefer a more lightweight installation that only includes the parts you actually need.
