Mr Leandro von Werra and Mr Harm de Vries offered insights into the development of large language models for code during their presentation. They showed how the BigCode project that they lead builds the most open and transparent models available today, making available all the data collection, filtering and training pipeline, and providing tools for developers to check whether their code is in the training dataset, to support opt out. They detailed the reasons for establishing a collaboration with Software Heritage: a shared engagement to contribute to a common good. «We partner with Software Heritage  to ensure that the source code used to build the models is accessible and identifiable, enhancing the transparency of our efforts.»

Open Science Panel

The following session included lively discussions by the Open Science Panel, which demonstrated how software source code is not only a tool for the preservation of the world’s software heritage but also an instrument at the service of Open Science emphasizing the importance of Open Source as an enabler for Open Science.

Mr Christopher S. Marcum, Senior Statistician and Senior Science Policy Analyst at the Office of the Chief Statistician of the United

States, shed light on the substantial source code repository maintained by the U.S. Bureau of Statistics (USB) on GitHub. «The big thing here that is relevant for Software Heritage is that by U.S. federal policy, federal agents are required to share their open-source code…» noting that it is a policy of the United States government for federal agencies to share, at a minimum, the metadata associated with their code repositories on code.gov, aligning with executive orders previously mentioned.

Ms Claudia Bauzer Medeiros, Professor at the University of Campinas (UNICAMP), declared that «Software Heritage is a treasure,» while quoting Paul Valéry

It depends on those who pass

Whether I am a tomb or treasure

Whether I speak  or am silent

The choice is yours alone.

~ Paul Valéry

Reminding us that «unless you understand its nature and reuse it, unless you take advantage of this treasure, we must make it abundantly clear that it’s not a mere repository to be buried as a tomb.» Claudia’ words highlighted the importance of recognizing and actively engaging with the wealth of knowledge preserved within Software Heritage, emphasizing its potential to drive innovation and progress in the digital age.
