Gemini 4 Carbon Tops CursorBench 4.0 Upon Cursor Launch
On November 11, Cursor officially announced that Gemini 4 Carbon is now available in Cursor. Under the high effort setting, the model topped Cursor's newly released CursorBench 4.0 leaderboard with a score of 60.4%, with the Medium tier close behind at 60.1%, beating out other models including Fable 5.2 and Gemini 4 Ar(dor?). It costs only about 9 dollars per task, notably lower than competitors. Google employee Ammaar confirmed that Gemini 4 Carbon sits on the performance/cost Pareto frontier of CursorBench, and independent testing by third-party evaluator LuminaBench also called its performance an "absolute monster" as it claimed the top spot.
