  const filePart = {
    type: 'file',
    mediaType: 'application/pdf',
    data: convertUint8ArrayToBase64(fileData), // Required conversion
  };

  After

  // Can use binary data directly
  const fileData = new Uint8Array([0, 1, 2, 3]);

  The experimental_generateImage method from the ai package now returnes revised prompts for OpenAI's image models.

  const prompt = 'Santa Claus driving a Cadillac';
  
  const { providerMetadata } = await experimental_generateImage({
    model: openai.image('dall-e-3'),
    prompt,
  });
  
  const revisedPrompt = providerMetadata.openai.images[0]?.revisedPrompt;
  
  console.log({
    prompt,
    revisedPrompt,
  });
