Google's Gemini 4 Argon Reaches Developer IDEs: Cursor Adds Frontier Model at Launch Pricing

Cursor, the AI-powered code editor, has integrated Google's newly released Gemini 4 Argon model, making the frontier LLM available to a significant developer audience hours after its debut. Announced by Google DeepMind on September 30, 2026, Gemini 4 Argon lands in Cursor at introductory pricing of $2 per million input tokens and $10 per million output tokens—the same launch rates Google announced. The model scores 52.8% on Cursor's proprietary CursorBench benchmark at default effort level, positioning it as a credible alternative to Claude Opus 5.5, which leads CursorBench's maximum-effort tier at 57.8%.
