Positioned as a major upgrade with improvements in reasoning, coding assistance, and task planning, this version is aimed at power users who rely on advanced agentic workflows. We begin by testing its performance in a 3D printer simulation, followed by browser-based OS tasks, logic puzzles, game generation, business idea development, and multimodal coding evaluations. These tests are designed to determine whether the Pro tier offers meaningful improvements—and whether the monthly subscription cost is justified.
