GrokImage.ai

GrokImage.ai is a freemium image generation service that puts several AI models in the one place, aimed at creators, marketers and developers who need quick visuals.

It includes multiple engine options you can pick for different jobs: Grok Imagine (xAI’s image model), Nano Banana 2 (Google Gemini 3 Flash, very fast at about 3–8 seconds per image and priced at 10 credits each, useful for batches and rapid prototyping) and Nano Banana Pro (Google Gemini 3 Pro, focused on photorealism and clearer text rendering for client-ready outputs).
