A JAX-based gravitational-wave population inference toolkit for parametric models

Installation | Documentation | Tutorials | Analysis on 🤗 | FAQs | Citing GWKokab

Overview

GWKokab is a high-performance, flexible, and easy-to-use toolkit for gravitational-wave population inference. Built on top of JAX, it enables efficient Bayesian inference for a wide range of parametric population models while remaining fully compatible with modern GPU/TPU-accelerated workflows.

The framework is designed to support scalable hierarchical inference and rapid experimentation with astrophysical population models, including mass, spin, redshift, and eccentricity distributions of compact binary mergers.
