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 the official OpenAI API directly?›

Ace Data Cloud provides a proxy interface that is 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?›

Reasoning models like o3, o3-pro, and o4-mini perform deep thinking before providing answers, making them particularly suitable for tasks that require 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 interactions. DALL·E 3 is a dedicated image generation model that supports various quality and size options, including Standard/HD.

Which model is good for Embeddings?›

We recommend text-embedding-3-small, which offers 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 that has good compatibility but is not as cost-effective as v3.
