Summary
Vercel added xAI's Grok Imagine Image 2.0 as a preview model on its AI Gateway on August 8, 2026, letting developers call the model as xai/grok-imagine-image-2.0-preview via generateImage with 1k or 2k output, batch generation, and image editing by passing source images in the prompt. Grok Imagine Image 2.0 improves instruction following, typography rendering, and precise editing, and xAI claims it ranks second on text-to-image and image-editing benchmarks.
What changed
Vercel AI Gateway listed xAI Grok Imagine Image 2.0 as a preview image model, callable through the AI SDK generateImage API with resolution, batch, and image-editing support, one day after xAI shipped the model as Quality Mode in its consumer apps.
Why it matters
Adding a frontier image model to the AI Gateway within a day of its release keeps Vercel positioned as a neutral, markup-free routing layer where developers reach new models without per-provider integration work, extending the gateway from text and video into higher-quality image generation and editing.
Evidence excerpt
The model is set to xai/grok-imagine-image-2.0-preview and called via generateImage through the Vercel AI Gateway, with resolution options of 1k or 2k, batch generation, and image editing by passing existing images in prompt.images.
