Cursor Launches a New AI Agent Experience to Take On Claude Code and Codex

Cursor launched Cursor 3 (codename "Glass"), an agent-first coding product that lets developers spin up AI agents to complete tasks autonomously — a direct response to Claude Code and OpenAI Codex. The pivot acknowledges that Cursor's core IDE product is less central going forward as agentic workflows dominate. This marks a significant strategic shift as Cursor fights for developer mindshare against the very AI labs it depends on as a customer.
