Brief

Metal TreeSHAP is an open-source project announced by Bojan Tunguz of Tabul AI on 2026-07-21 that implements accelerated TreeSHAP (Shapley Value) computations optimized for Apple silicon. The thread (post 1 of 11) presents the library as a major Tabul AI effort to speed up a widely used interpretability algorithm for decision-tree models.

Why it matters

Metal TreeSHAP is an open-source library launched by Tabul AI (Bojan Tunguz/@tabul_ai) on 2026-07-21 that targets computation of Shapley Values.

Key details

  • The project claims to dramatically accelerate TreeSHAP/Shapley Value computation specifically on Apple silicon (announced in a multi-post thread labeled 1/11).
Source evidence

Exciting news. We just launched Metal TreeSHAP - an open source library that dramatically accelerates computation of Shapley Values on Apple silicon.

We are very excited to share one of the big projects that we have been working on at @Tabul_AI Metal TreeSHAP. Shapley Values are one of the most reliable and most widely used tools in Machine Learning interpretability.
