The index was announced on Thursday Launch of Cursor 3, a new product interface that allows users to spin AI coding agents to complete tasks on their behalf. The product, developed under the codename Glass, is Cursor’s answer to proxy encryption tools like Anthropic’s Claude Code And OpenAI’s Codex, which has launched with millions of developers in recent months.
“In the last few months, our profession has completely changed,” Jonas Neely, one of Cursor’s engineering leads, said in an interview with WIRED. “A lot of the products that brought Cursor here aren’t important going forward anymore.”
Cursor increasingly finds itself in competition with leading AI labs for developers and enterprise customers. The company pioneered one of the first and most popular ways for developers to code using AI models from OpenAI, Anthropic, and Google, making Cursor one of these companies’ largest AI customers. But in the last 18 months, OpenAI and Anthropic have launched Proxy coding products Their own, and they started offering them through highly subsidized subscriptions which put a strain on Cursor’s business.
While Cursor’s core product lets developers code in an integrated development environment (IDE) and leverage an AI model for help, new products like Claude Code and Codex are centered around letting developers offload entire tasks to an AI agent — sometimes running multiple agents at the same time. Cursor 3 is the startup’s version of its “agent-first” programming product. According to Nelly, the product is optimized for a world where developers spend their days “talking to different agents, checking in with them, seeing the work they’ve done,” rather than writing code themselves.
Cursor is launching its new proxy coding interface inside its existing desktop application, where it will live alongside the IDE. In the center of the new window in Cursor, there’s a text box where users can type in the task they’d like the AI agent to complete, in natural language, looking more like a chatbot than a programming environment. Press enter, and the AI agent runs without requiring the developer to write a single line of code. In the sidebar on the left, developers can view and manage All artificial intelligence agents They have a run in indicator.
What sets Cursor 3 apart, compared to the desktop applications of Claude Code and Codex, is that it integrates the agent-first product with Cursor’s AI-powered development environment. In a demo, Alexi Robbins, Cursor’s other co-lead of engineering for Cursor 3, showed WIRED how users can ask an agent in the cloud to spin up a feature, and then review the generated code locally on their computers.
Nelly and Robbins argue that it doesn’t matter which interface developers spend their time on, they just want people to use the cursor.
Competing with artificial intelligence laboratories
I visited Cursor’s office in San Francisco’s North Beach neighborhood last week. The startup is reportedly raising fresh capital at a price $50 billion valuation– Nearly double what was evaluated in finance circular Last fall – it expanded into an old movie theater. Cursor employees used to throw their shoes in a pile by the door upon entering, but now there is a row of large shoe racks, indicating one way the company is growing.
However, Cursor still feels like a startup. Employees tell me that’s part of the appeal of working there; The company can ship quickly and doesn’t feel like a big company. But as it finds itself racing to catch up with Anthropic and OpenAI in the race for efficient programming, this confusion may not be enough. This battle — aimed at creating the best AI coding agent — may be Cursor’s most capital-intensive chapter yet.
