Where AI meetsBayesian statistics
We build fast Bayesian methods for the age of AI that transcend disciplines and live beyond the words of a paper.
Ideas, tools, and people
Our work spans methodological research, open-source infrastructure, and collaborations across scientific domains.

What we build


Generative AI for Bayesian Statistics
BayesFlow
BayesFlow is a Python library for simulation-based inference with generative AI. It provides users and researchers with a user-friendly API for amortized Bayesian workflows, AI research, and multi-backend support via Keras3.
Model-based fNIRS analysis with AI
fNIRS SimBox
We are developing a full-head 3D fNIRS simulator that will be used for in silico neuroimaging and model-based analysis. We are also creating AI models for real-time model calibration and data interpretation, targeting application areas like surgical training.

Learn All Your Models Once
CogFormer
CogFormer is the first incarnation of the BayesGPT project, allowing cognitive modelers to perform near-instant Bayesian modeling on a combinatorial space of design configurations. The web app lets you interact with a pre-trained version of CogFormer v1.
