Gemini API
Google's Most Powerful AI Models
Easily integrate the full range of Google Gemini models through the OpenAI-compatible format. Supports deep reasoning, multimodal input, and streaming—pay as you go, at prices lower than the official rates.
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. However, 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 code, or compare the performance of both 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 responding, 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, making it easy to handle 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.
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="")
