Separate account system note

Why use a dedicated image route

Image generation has different latency and payload characteristics from text chat. A separate image route is better for upload-heavy, batch-heavy, or latency-sensitive image workflows.

Resolution and pricing strategy

The current public message of this service is that 1K, 2K, and 4K sit under the same pricing tier for this workflow family, with practical single-image costs kept low. Exact pricing still follows the live platform display.

Native 4K versus upscaled 4K

Native 4K
  The model generates at 4K quality directly
  Best for texture fidelity, edge clarity, facial stability, packaging details, and post-crop flexibility

Upscaled 4K
  The image starts smaller and is later enlarged by AI
  Best for output size and throughput efficiency
  Risk: soft small text, guessed details, weaker complex texture fidelity

The shortest rule is: upscaled 4K solves output size; native 4K solves actual image quality.

API integration suggestion

For code-driven image generation, route OpenAI-compatible image requests tohttps://img.gpt88.cc and use the official gpt-image-2 image endpoint family.

curl https://img.gpt88.cc/v1/images/generations \
  -H "Authorization: Bearer $GPT88_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-image-2",
    "prompt": "Premium ecommerce skincare poster, glass bottle, silver pump, soft natural light, minimal luxury look, no text, no watermark",
    "size": "1024x1024",
    "quality": "high",
    "n": 1
  }'

• Image API for official endpoint structure.
• Agent Image Studio for manual drafting workflows.

Recommended workflow

1. Draft manually in agent.gpt88.cc.
2. Lock the prompt and composition direction.
3. Move stable prompts into API scripts via https://img.gpt88.cc.
4. Use cheaper / faster modes for batch support assets and higher-quality modes for covers, ads, and hero images.
