Open-source model interpretability for PyTorch
Integrated Gradients, GradientShap, Saliency, Occlusion, DeepLIFT and related methods behind a single consistent interface.
Works across vision, text and other modalities, so the same interpretability workflow applies to different model types.
Supports most PyTorch model architectures and requires little or no modification to the original network.
An open-source, generic library for interpretability research where new algorithms can be implemented and benchmarked.
The data, evaluations and systems behind AI that has to be right.
Human-sourced and expert-annotated training data, including specialist contributors with advanced degrees, at the quality bar frontier labs require.
Public leaderboards plus private benchmarks that test model capability and safety for the most ambitious AI developers.
Platform and services teams that pick the right use case, build the system and take ownership of the outcome.
Agentic systems designed around measurable business outcomes across private equity portfolios, energy and healthcare operations.
