Nokia analyzes 50M+ lines of code in two weeks with Cursor

Nokia’s Core Networks division is using Cursor’s AI-assisted, multi-agent capabilities to modernize workflows supporting highly regulated 5G mobile voice and data services that require five-nines reliability. Two engineers analyzed a hybrid, multi-repository codebase exceeding 50 million lines in two weeks, producing an evidence-based plan to break down a monolithic architecture into distributed services while reportedly avoiding months of work by more than a dozen specialists. Nokia also used Cursor to create a project-management tool in under a week that automated and visualized about 80% of a complex 5G function deployment workflow, and it has reduced software-defect root-cause investigations from weeks to days by analyzing logs, tickets, code, and debugging traces in parallel. The company is extending the technology across its software development lifecycle for requirements gathering, product requirements documents, architectural planning, and future automated cataloging of network elements, with the goal of pairing specialized AI agents with employees across development and delivery tasks.
