Grok Imagine Pro is xAI's latest image generation model, released in March 2026, offering a significant quality upgrade over the base Grok Imagine model. Built on the same Aurora engine, it delivers more refined results in fine-grained areas such as detail, lighting and shadow, and text rendering, making it well-suited for professional content creation and commercial-grade work.It also supports an extensive range of aspect ratios, including the square format (1:1), 9:16 optimized for vertical social video, 16:9 suited for horizontal YouTube thumbnails, as well as 3:4, 4:3, 2:3, 3:2, 9:19.5, 19.5:9, 9:20, 20:9, 1:2, and 2:1 — accommodating a broad spectrum of production purposes.
