In this video, we take a hands-on look at Grok 4.3, testing its performance across a range of real-world tasks to determine whether it can compete with other frontier models.
We begin with a technical overview and then move into a series of practical tests. These include browser-based workflows, scene generation, simulation tasks, coding challenges in C++, 3D printer simulations, and multimodal website creation.
