How to Build a Ai Photo Generator

// Photorealistic image generation via Replicate (Flux Pro)
  async function generatePhoto(prompt, options = {}) {
  const { width = 1024, height = 1024, steps = 25 } = options;

  const response = await fetch('https://api.replicate.com/v1/predictions', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.REPLICATE_API_TOKEN}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      version: 'black-forest-labs/flux-1.1-pro',
      input: {
        prompt: `photorealistic, ${prompt}, shot on Canon EOS R5, 85mm lens, natural lighting`,
        width, height,
        num_inference_steps: steps,
        guidance_scale: 3.5
      }
    })
  });

  const prediction = await response.json();
  // Poll for completion
  return prediction.urls.get;
  }
