Why Use Gemini Through Ace Data Cloud?

Google's Gemini is one of the most cutting-edge AI models today. Gemini 2.5 Pro excels in programming, mathematics, and reasoning benchmarks, with an ultra-long context window of millions of tokens. However, using the Google AI API directly requires addressing issues such as regional restrictions and billing configurations.

Ace Data Cloud offers comprehensive Gemini API proxy services, using OpenAI compatible format—you can directly call Gemini using the OpenAI SDK without modifying your code to switch from GPT to Gemini or to compare their performances side by side.

All Features of Gemini API

Unlock the full capabilities of Gemini through OpenAI compatible interfaces

🔌

OpenAI Compatible Format

Use Gemini through the /v1/chat/completions interface, fully compatible with the OpenAI SDK. Seamless switching, zero code changes.

🧠

Deep Reasoning

The Gemini 2.5 series has built-in deep reasoning capabilities, where the model engages in structured thinking before answering, significantly enhancing performance on complex tasks.

👁️

📚

Million-Token Context

Gemini 2.5 Pro supports a context window of up to 1 million tokens, easily handling ultra-long documents, code repositories, and complex dialogues.

⚡

Streaming

Supports SSE streaming, returning generated content in real-time. Set stream: true to receive a token-by-token output stream.

📄

Structured Output

Specify JSON output format using the response_format parameter, along with JSON Schema to obtain structured API responses.

Python

from openai import OpenAI
client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.acedata.cloud/v1"
)
response = client.chat.completions.create(
    model="gemini-2.5-flash",
    messages=[
        {"role": "user", "content": "What is quantum computing?"}
    ],
    stream=True
)
for chunk in response:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")

Frequently Asked Questions

Everything you need to know about using the Gemini API

What is the difference between using Google AI API directly? ▾

Ace Data Cloud is a proxy service for the Google Gemini API. We provide the exact same Gemini models and capabilities, but with additional support for OpenAI compatible formats, allowing you to call Gemini directly using the OpenAI SDK. Your requests are ultimately processed by Google's Gemini models, ensuring identical quality.

Does it support OpenAI SDK? ▾

Yes! Our Chat Completions API is fully compatible with the OpenAI SDK (Python, Node.js, Go, etc.). Just modify the base_url to https://api.acedata.cloud/v1 and set the model to the Gemini model name. Your existing OpenAI code requires almost no modification.

Which Gemini models are supported? ▾

We support the entire range of Gemini models, including Gemini 2.0 Flash, Gemini 2.5 Flash, Gemini 2.5 Pro, Gemini 3.0 Pro, Gemini 3.1 Pro, etc. We will follow up promptly after Google releases new models.

What is deep reasoning (Thinking)? ▾

The Gemini 2.5 series has built-in deep reasoning capabilities. The model undergoes a structured thinking process before answering, significantly enhancing performance in tasks such as mathematics, logical reasoning, and complex programming. This is a native feature of Gemini 2.5, requiring no additional configuration.

What is the pricing model? ▾

Charged based on Token usage, with separate pricing for input Tokens and output Tokens. Different models have different prices—Flash is the cheapest, and the Pro series is the most expensive. No subscription fees, no monthly fees, pay only for what you use. Available immediately after top-up, and the balance never expires.

Does it support multimodal input? ▾

Yes. Gemini natively supports multimodal input, allowing you to attach Base64 encoded images or image URLs in messages, and Gemini will understand the image content and respond in conjunction with the text. Supports JPEG, PNG, GIF, and WebP formats.

Can GPT, Claude, and Gemini be used simultaneously? ▾

Yes! Ace Data Cloud provides multiple LLMs such as GPT, Claude, Gemini, Kimi, etc., through a unified OpenAI compatible interface. You only need to change the model parameter to switch between different models, with the API format being completely consistent, requiring no maintenance of multiple codebases.
