Open Source for Science Fund

9 July

Our inaugural call, Open Source for the Life Sciences, drew hundreds of proposals spanning a wide range of biology disciplines and computational approaches. If you use agents or AI models as a scientist, open source software is what makes it possible.

os4science.orgHugging Face 🤝 Open Source for Science FundThe Open Source for Science Fund and Hugging Face are joining forces to support the software stack behind open source scientific AI models.

We're joining forces with @hf.co to identify the software libraries that scientific model contributors rely on most and explore opportunities to support the maintainers behind them. os4science.org/news/hugging...

Exciting new funding opportunity for open source software in the life sciences: @os4science.org has launched its inaugural call for proposals. Definitely worth a look if you’re building in this space!

Open Source for Science Fund@os4science.org

📣 New funding opportunity. Today, we're launching our inaugural call for proposals for open source software that underpins data-intensive research and AI-driven discovery in the life sciences. 1/ os4science.org/funding_oppo...

View full thread

Two application tracks: Track 1. domain-specific software tools across a broad range of disciplines in the life sciences (up $250,000) Track 2. foundational libraries as well as collaborations among related projects within the same software ecosystem (up to $1,000,000) 3/

Across these two categories, we will give priority to applications that enable large-scale data analysis and AI-driven applications and workflows. Letters of intent (LOI) are due June 8, 2026. Full application details at: os4science.org/funding_oppo... 4/4

We're seeking proposals that address significant technical bottlenecks or delivers critical capabilities in these software projects. Proposals should target a clear technical challenge that serves critical needs for their research audience. 2/
