Use the OpenAI SDK with G0I

Already built on the OpenAI SDK? You do not need a new library. Point the SDK at G0I by changing one setting — base_url — and every model is available.

The only change: base_url

G0I implements the OpenAI API. Keep the OpenAI SDK; just set base_url to https://g0i.ai/v1 and use your G0I key.

Python

from openai import OpenAI
client = OpenAI(
    api_key="$G0I_KEY",
    base_url="https://g0i.ai/v1",   # the only change
)
resp = client.chat.completions.create(
    model="claude-opus-4-7",
    messages=[{"role": "user", "content": "Write a haiku about APIs"}],
    stream=True,
)
for chunk in resp:
    print(chunk.choices[0].delta.content or "", end="")

Node.js

import OpenAI from "openai";
const client = new OpenAI({
  apiKey: process.env.G0I_KEY,
  baseURL: "https://g0i.ai/v1",   // the only change
});
const r = await client.chat.completions.create({
  model: "gemini-3-pro-preview",
  messages: [{ role: "user", content: "Hello" }],
});
console.log(r.choices[0].message.content);

What carries over

Streaming — stream: true works unchanged.
Tool / function calling — same tools parameter.
Vision — image inputs in the same message format.
Every SDK feature — retries, timeouts, async clients.

The difference: the model field now reaches 470+ models. See the catalog or the quickstart.

Frequently asked questions

Do I need a special G0I SDK?
No. The standard OpenAI SDK (Python, Node, and others) works — only the base_url changes.

Will tool calling and streaming still work?
Yes. G0I is built to the OpenAI spec, so streaming, tool calling and vision all work unchanged.

Which base URL do I use?
https://g0i.ai/v1
