xAI launches the Grok Imagine Image API
xAI launched a revamped generation of Grok Imagine image models as a programmable API for standard image generation and editing.
What happened
Event details
On January 28, 2026, xAI made its revamped image-generation stack available through the Grok Imagine API. The current standard model, grok-imagine-image, accepts text prompts and reference images and returns images, with generation, editing, batch variations, aspect-ratio controls, and 1K or 2K output. In xAI's launch materials, partner feedback from ComfyUI highlighted text-to-image work in retro anime and cyberpunk styles, while Flora emphasized scene-level style, mood, and physical realism. These are partner testimonials carried by the vendor, not independent evaluations. xAI has not disclosed the model's parameter count or underlying architecture.
Assessment
Why it matters
The release moved Grok's image generation and editing from an in-product feature into a standard API that third-party creative tools could integrate. Partner feedback points to practical appeal for stylized creation and rapid visual ideation, but independent evaluation and technical disclosure remained limited.
