Use generateImage with aiStats.imageModel(...). 
import { aiStats } from "@ai-stats/ai-sdk-provider";
import { generateImage } from "ai";

const result = await generateImage({
  model: aiStats.imageModel("openai/gpt-image-1"),
  prompt: "A minimalist poster of a lighthouse at dawn.",
  size: "1024x1024",
});

console.log(result.images[0].mediaType);
console.log(result.images[0].uint8Array.length);
console.log(result.providerMetadata);

​
Notes

  • Available size values depend on the selected model.
  • URL-backed gateway image responses are normalized into the AI SDK file output shape, so uint8Array and mediaType are the stable fields to read first.
  • For deterministic workflows, persist prompt + model + params together.
  • Prefer storing returned image metadata with asset references.
