 Matbench Discovery is an [interactive leaderboard](https://janosh.github.io/matbench-discovery/models) and associated [PyPI package](https://pypi.org/project/matbench-discovery) which together make it easy to rank ML energy models on a task designed to simulate a high-throughput discovery campaign for new stable inorganic crystals.
 
-So far, we've tested 8 models covering multiple methodologies ranging from random forests with structure fingerprints to graph neural networks, from one-shot predictors to iterative Bayesian optimizers and interatomic potential relaxers.
