Hengzhi’s study on collaborative development paradigm divergence between open source software and open source AI models is accepted by CSCW 2026. Congratulations to Hengzhi!

This work presents the first systematic, large-scale study comparing collaborative development paradigms between traditional open source software (OSS) and open source AI models (OSM). Analyzing over 2.8 million repositories and combining statistical, social network, and interview-based methods, the paper uncovers fundamental differences in collaboration intensity, openness, and user innovation between the two ecosystems. As AI development increasingly embraces open-source practices, this research fills a critical knowledge gap and lays an empirical foundation for understanding and improving collaborative AI development.
