Quickstart

Prerequisites

  1. Create a free account at platform.qubrid.com
  2. Generate your API key from the API Keys section
  3. Replace QUBRID_API_KEY in the code below with your actual key

Python

from openai import OpenAI

# Initialize the OpenAI client with Qubrid base URL
client = OpenAI(
    base_url="https://platform.qubrid.com/v1",
    api_key="QUBRID_API_KEY",
)

# Create a streaming chat completion
stream = client.chat.completions.create(
    model="Qwen/Qwen3-Plus",
    messages=[
      {
        "role": "user",
        "content": "Explain quantum computing in simple terms"
      }
    ],
    max_tokens=4096,
    temperature=0.7,
    top_p=1,
    stream=True
)

# If stream = False comment this out
for chunk in stream:
    if chunk.choices and chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="", flush=True)
print("\n")

# If stream = True comment this out
print(stream.choices[0].message.content)

JavaScript

import OpenAI from "openai";

// Initialize the OpenAI client with Qubrid base URL
const client = new OpenAI({
  baseURL: "https://platform.qubrid.com/v1",
  apiKey: "QUBRID_API_KEY",
});

// Create a streaming chat completion
const stream = await client.chat.completions.create({
  model: "Qwen/Qwen3-Plus",
  messages: [
    {
      role: "user",
      content: "Explain quantum computing in simple terms",
    },
  ],
  max_tokens: 4096,
  temperature: 0.7,
  top_p: 1,
  stream: true,
});

// If stream = false comment this out
for await (const chunk of stream) {
  if (chunk.choices[0]?.delta?.content) {
    process.stdout.write(chunk.choices[0].delta.content);
  }
}
console.log("\n");

// If stream = true comment this out
console.log(stream.choices[0].message.content);

Go

package main

import (
	"bufio"
	"bytes"
	"encoding/json"
	"fmt"
	"net/http"

	url := "https://platform.qubrid.com/v1/chat/completions"

	jsonData, _ := json.Marshal(data)
	req, _ := http.NewRequest("POST", url, bytes.NewBuffer(jsonData))
	req.Header.Set("Authorization", "Bearer QUBRID_API_KEY")
	req.Header.Set("Content-Type", "application/json")

	client := &http.Client{}
	res, _ := client.Do(req)
	defer res.Body.Close()

	scanner := bufio.NewScanner(res.Body)
	for scanner.Scan() {
		line := scanner.Text()
		if line != "" {
			fmt.Println(line)

Live Example

Prompt: Summarize the key points of the latest climate change report
Response:
Key Points — Climate Change (Summary)

1. Global temperatures are rising faster than projected
   Average global surface temperature has increased by approximately 1.1°C
   above pre-industrial levels. Without intervention, we are on track for
   1.5°C by the early 2030s.

2. Extreme weather events are intensifying
   Heatwaves, droughts, floods, and wildfires are becoming more frequent
   and severe. Vulnerable regions — particularly sub-Saharan Africa,
   South Asia, and small island states — face disproportionate impacts.

3. Sea levels are accelerating
   Ice sheet loss from Greenland and Antarctica is accelerating. Sea level
   rise threatens hundreds of millions of coastal residents by 2100.

4. Emissions must peak before 2025 to limit warming to 1.5°C
   Global greenhouse gas emissions need to fall 43% by 2030 (vs 2019 levels)
   to stay on the 1.5°C pathway. Current commitments fall significantly short.

5. Adaptation is now unavoidable
   Even under optimistic scenarios, significant adaptation investment is
   required for agriculture, water systems, infrastructure, and public health.

6. Financing remains the critical gap
   Developing nations require $1–1.3 trillion/year by 2030 in climate finance.
   Current flows represent a fraction of that need.

Bottom line: The window to avoid the worst outcomes is narrowing rapidly.
Immediate, large-scale action on emissions reduction and adaptation financing
is required across all sectors and geographies.

Playground Features

The Qubrid AI Playground lets you interact with Qwen3 Plus directly in your browser — no setup, no code, no cost to explore.

🧠 System Prompt

Set the model’s role, tone, and language preferences before the conversation begins — ideal for multilingual customer support bots, branded writing assistants, or scoped analysis tools.
Example: "You are a multilingual customer support agent for a global SaaS
platform. Respond in the same language the user writes in. Be concise,
friendly, and always offer a next step or resolution."
Set your system prompt once in the Qubrid Playground and it applies across every turn of the conversation.

🎯 Few-Shot Examples
