What we fund
We target software that serves as foundational infrastructure for data-intensive science and AI-driven discovery. Rather than funding AI models themselves, we invest in the open source software stack that models depend on, ensuring it is robust, interoperable, and sustainable. See individual calls for proposals for more on what we fund.
Data management and representation
Tools for representing, managing, curating, and structuring scientific data for use in model training. These are the foundation AI models are built on.
Model training and evaluation
Infrastructure for reproducible training, benchmarking, and validation of scientific AI models.
Hardware acceleration and HPC
Libraries and tools that help scientists take advantage of GPUs, TPUs, and high-performance computing environments.
Agentic workflows and automation
Workflow systems and APIs that support autonomous, agentic scientific experimentation at scale.
