Native OpenAI SDK Direct Connection

Modify base_url to access the full range of OpenAI models through Ace Data Cloud, fully compatible with the official SDK.

Python
from openai import OpenAI

client = OpenAI(
base_url="https://api.acedata.cloud",
api_key="YOUR_API_KEY"
)


Chat Completions


response = client.chat.completions.create(
model="gpt-5",
messages=[
{"role": "user", "content": "Explain the core concepts of machine learning"}
]
)
print(response.choices[0].message.content)


Image Generation


image = client.images.generate(
model="gpt-image-1",
prompt="A futuristic city at sunset",
n=1
)
print(image.data[0].url)

Frequently Asked Questions

Common questions about using the OpenAI API

What is the difference between using this and directly using the official OpenAI API?›

Ace Data Cloud provides a proxy interface fully compatible with the official OpenAI format, without the need to register an OpenAI account or bind an overseas credit card. One API Key can access multiple models such as OpenAI, Claude, Gemini, Grok, etc.

What is the difference between GPT-5 and GPT-4o?›

GPT-5 is OpenAI's latest flagship model, surpassing GPT-4o in reasoning, creativity, and knowledge capabilities. GPT-4o is a well-validated cost-effective choice, suitable for cost-sensitive scenarios.

What scenarios are the o series reasoning models suitable for?›

Models like o3, o3-pro, and o4-mini perform deep thinking before providing answers, particularly suitable for tasks requiring deep reasoning such as mathematical calculations, logical reasoning, and code analysis. o3-mini and o4-mini offer lower-cost reasoning capabilities.

What is the difference between GPT Image and DALL·E 3?›

GPT Image 1 / 1.5 is OpenAI's latest native image generation model, directly integrated into the GPT model, supporting more natural text-image interaction. DALL·E 3 is a dedicated image generation model, supporting various quality and size options including Standard/HD.

Which model is good for Embeddings?›

It is recommended to use text-embedding-3-small, which has the best cost-performance ratio ($0.0027 / million Tokens). For higher precision, use text-embedding-3-large ($0.017 / million Tokens). ada-002 is an older model, compatible but not as cost-effective as v3.
