Image Generation API

Generate, edit, dan variasi gambar menggunakan AI. Use case: thumbnail generator, avatar builder, product mockup, illustration.

DALL-E (OpenAI)

const response = await openai.images.generate({
  model: "dall-e-3",
  prompt: "A minimalist illustration of a web developer coding, flat design, blue tones",
  n: 1,
  size: "1024x1024",
  quality: "standard", // or "hd"
});

const imageUrl = response.data[0].url;

Image Analysis (Vision)

// GPT-4o bisa "melihat" gambar
const response = await openai.chat.completions.create({
  model: "gpt-4o",
  messages: [{
    role: "user",
    content: [
      { type: "text", text: "Apa yang ada di gambar ini?" },
      { type: "image_url", image_url: { url: imageUrl } },
    ],
  }],
});

Alternatives

• Stability AI — Stable Diffusion API, lebih murah
• Replicate — Run any open-source model via API
• Midjourney — Kualitas tertinggi, tapi Discord-based (tidak ada direct API)

Best Practices

• Cache generated images — jangan generate ulang untuk prompt yang sama
• Simpan di object storage (S3/R2), bukan serve dari API URL (expired)
• Content moderation — filter prompt yang inappropriate
• Cost control — image generation mahal ($0.04-0.12 per gambar)
