Cursor's Third Era: Cloud Agents — ft. Sam Whitmore, Jonas Nelle, Cursor
https://cursor.com/blog/third-era
Cursor Cloud Agents: Tested PRs, Demo Videos, Parallel Model Swarms, and the Future of Agentic Coding
swyx catches up with Jonas and Sam in the beautiful new Cursor office, recapping Cursor’s latest cloud agents launch and how giving agents full cloud VMs enables them to onboard repos, run code, and test changes end-to-end before returning a PR, often with a short demo video and optional live remote desktop/terminal access. We discuss how videos reduce review bottlenecks, when testing or bug reproduction is triggered (including /no-test and /repro), and examples spanning UI tweaks, backend error handling, and a bug where removed image attachments were still sent. The team highlights parallel agents and best-of model comparisons, experiments with multi-provider “council” synthesis, subagents, Datadog MCP–based diagnostics, transcript-based debugging/forking, and long-running “grind mode.” They predict wider “throughput” via swarms, rising spend per developer, cloud agents overtaking local agents, and new bottlenecks in review, CI/CD, and production pipelines.
