What is SWE-Lancer?

SWE-Lancer is a large-scale benchmark launched by OpenAI to evaluate the performance of cutting-edge language models (LLMs) in freelance software engineering tasks. It includes over 1400 tasks from Upwork, with a total value of $1 million, divided into individual contributor (IC) tasks and management tasks. IC tasks range from simple fixes to complex feature development, while management tasks require the model to select the optimal technical solution. SWE-Lancer's task design closely resembles real-world software engineering scenarios, involving complex scenarios such as full-stack development and API interaction. Through validation and testing by professional engineers, the benchmark assesses the model's programming capabilities and measures its economic efficiency in practical tasks.
