OpenAI is developing a research program to assess the economic impacts of code generation models and is inviting collaboration with external researchers. Rapid advances in the capabilities of large language models (LLMs) trained on code have made it increasingly important to study their economic impacts on individuals, firms, and society. Codex – an LLM developed by OpenAI by fine-tuning GPT‑3 on billions of lines of publicly available code from GitHub – has been shown to generate functionally correct code 28.8% of the time on a sample of evaluation problems (Chen et al. 2021). This may have important implications for the future of coding and the economics of the industries that depend on it. In this document, we lay out a research agenda to assess the effects of Codex on economic factors of interest to policymakers, firms, and the public. We make a case for this research agenda by...
