Why Use Gemini Through Ace Data Cloud?

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

Ace Data Cloud provides a complete Gemini API proxy service in an OpenAI-compatible format—you can call Gemini directly using the OpenAI SDK, switch from GPT to Gemini without modifying your code, or compare their performance side by side.

All Gemini API Features

Unlock all of Gemini's capabilities through an OpenAI-compatible interface

🔌

OpenAI-Compatible Format

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

🧠

Deep Reasoning (Thinking)

The Gemini 2.5 series includes built-in deep reasoning capabilities. Models perform structured thinking before answering, significantly improving performance on complex tasks.

👁️

Multimodal Input

Supports combined image + text input. Gemini can analyze images, read documents, and understand charts—native multimodal capabilities.

📚

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 conversations.

⚡

Streaming

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

📄

Structured Output

Specify the JSON output format with the response_format parameter, and use 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="")

Response

{
  "id": "chatcmpl-20260228052207317219436lM3F0qIx",
  "object": "chat.completion",
  "created": 1772256128,

Your requests are ultimately processed by Google's Gemini models, with exactly the same quality.

Does it support the OpenAI SDK? ▾

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

Which Gemini models are supported? ▾

We support the full Gemini model lineup, including Gemini 2.0 Flash, Gemini 2.5 Flash, Gemini 2.5 Pro, Gemini 3.0 Pro, Gemini 3.1 Pro, and more. We will follow up on new models as soon as Google releases them.

What is deep reasoning (Thinking)? ▾

This is a native feature of Gemini 2.5 and requires no additional configuration.

How does pricing work? ▾

Billing is based on Token usage, with input Tokens and output Tokens priced separately. Prices vary by model—Flash is the cheapest, while the Pro series is the most expensive. No subscription fees or monthly fees; pay only for what you use. Available immediately after topping up, and your balance never expires.

Does it support multimodal input? ▾

Yes. Gemini natively supports multimodal input. You can attach Base64-encoded images or image URLs in messages, and Gemini will understand the image content and respond in combination with the text. JPEG, PNG, GIF, and WebP formats are supported.

Can I use GPT, Claude, and Gemini at the same time? ▾

Yes! Ace Data Cloud provides multiple LLMs, including GPT, Claude, Gemini, and Kimi, through a unified OpenAI-compatible interface. You only need to change the model parameter to switch between different models. The API format is completely consistent, so there is no need to maintain multiple codebases.
