Two engineers ran Cursor AI code analysis across more than 50 million lines of Nokia Core Networks code in two weeks. The team had expected the same work to take a dozen specialists several months with custom tooling, according to Cursor Blog.
The analysis spanned a hybrid codebase in C, C++ and Go spread over numerous repositories. It produced an evidence-based plan to break down a monolithic 5G core architecture into a more distributed, service-based design.
Nokia Core Networks builds cloud native functions for 5G voice and data in environments where five-nines reliability is required.
Why it matters for AI and startups
Cursor is showing up less as an autocomplete and more as a multi-agent orchestration platform. Engineers supervise parallel agents that flag hotspots, suggest triage steps and draft PRDs and designs.
That shift showed up in two other Nokia pilots. One engineer went from problem statement to PRD to a working project-management tool in under a week, automating about 80% of a workflow that normally took 6 to 10 managers. For customer-impacting defects, root cause analysis dropped from weeks to days once logs, tickets, traces and code were loaded into Cursor.
