GPT Image 2

能力

• 透過目前公開端點生成圖片
• 即時 Schema 提供時支援圖片編輯或參考圖控制
• 目前參數包括 prompt, image_urls, size

限制

• 模型能力與參數範圍可能更新，正式環境應鎖定並驗證使用的參數組合
• 未出現在即時 Request Schema 中的參數不應假定可用
• 非同步任務需要處理輪詢、失敗、逾時與內容安全狀態

典型情境

• 產品原型與自動化內容工作流程
• 批次媒體生成與程式化創作
• 需要統一驗證、計費與呼叫記錄的多模型應用

價格與計費範例

• Input tokens | 5 | 1M tokens
• Output tokens | 30 | 1M tokens
• Image tokens | 8 | 1M tokens

API 串接範例

cURL

curl -X POST 'https://api.uniall.ai/v1/images/generations' \
  -H 'Authorization: Bearer $UNIALL_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"model":"gpt-image-2","n":1,"output_format":"png","prompt":"Describe the output you want","quality":"auto","size":"auto"}'

Python

import json
import requests

payload = json.loads(r'''{"model":"gpt-image-2","n":1,"output_format":"png","prompt":"Describe the output you want","quality":"auto","size":"auto"}''')
response = requests.post(
    "https://api.uniall.ai/v1/images/generations",
    headers={"Authorization": "Bearer " + UNIALL_API_KEY},
    json=payload,
)
response.raise_for_status()
result = response.json()

JavaScript

const response = await fetch("https://api.uniall.ai/v1/images/generations", {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${process.env.UNIALL_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({"model":"gpt-image-2","n":1,"output_format":"png","prompt":"Describe the output you want","quality":"auto","size":"auto"}),
});

if (!response.ok) throw new Error(`HTTP ${response.status}`);
const result = await response.json();
