Abstract

Generative AI is likely to transform processes of innovation, yet it is unclear what trajectory this transformation will follow. The uncertainty arises because certain problems, where a provision of detailed context results in precise solutions, are best approached through interpolative (within-the-box) thinking, whereas other problems, where providing detailed context is either difficult or ineffective, demand extrapolative (out-of-the-box) thinking. How GenAI affects tasks needing extrapolative vs. interpolative thinking is an open empirical question. We study this question within the open-source context, focusing on the launch of GitHub Copilot. Specifically, we leverage a natural experiment in which GitHub Copilot selectively rolled out support for Python but not for R. We observe a significant jump in overall contributions, suggesting that GenAI effectively enhances outcomes for voluntary contributors. Interestingly, Copilot’s launch increased maintenance-related contributions, which need interpolative thinking, significantly more than code-development contributions, which need extrapolative thinking.

The Impact of Large Language Models on Open-source Innovation: Evidence from GitHub Copilot

Generative AI is likely to transform processes of innovation, yet it is unclear what trajectory this transformation will follow. The uncertainty arises because certain problems, where a provision of detailed context results in precise solutions, are best approached through interpolative (within-the-box) thinking, whereas other problems, where providing detailed context is either difficult or ineffective, demand extrapolative (out-of-the-box) thinking. How GenAI affects tasks needing extrapolative vs. interpolative thinking is an open empirical question. We study this question within the open-source context, focusing on the launch of GitHub Copilot. Specifically, we leverage a natural experiment in which GitHub Copilot selectively rolled out support for Python but not for R.
