opub, donated compute for open

opub is a public compute commons that connects donors with open source projects needing computational resources. Donors contribute funding for cloud compute, which maintainers of open source projects can then spend on API access to over 30 coding models. All spending is tracked publicly, creating transparency about how donated resources are used. The platform addresses a real constraint for open source development: running and training AI models requires significant compute resources, which many projects lack funding for. By aggregating donations into a shared pool, opub makes these tools accessible to maintainers who might otherwise be unable to afford them. Projects gain API keys to spend from their allocated budget across a range of models, from code generation to analysis tools. It sits somewhere between a grant programme and a utility, designed for projects serious about using AI tools but operating on limited budgets. The public token spend creates accountability and helps donors see real-world impact of their contributions.
