How to Use Qwen 3.5 Plus API for Free in 2026

How to Use Qwen 3.5 Plus API for Free in 2026

Qwen 3.5 Plus is one of the strongest open-weight models available today. Developed by Alibaba Cloud, it delivers impressive coding performance, advanced reasoning, and a 128K context window that can process entire codebases in a single prompt. But you do not need to spend a dime to start using it.

This guide covers every free method to access the Qwen 3.5 Plus API, complete with working code examples in Python and TypeScript.

Why Qwen 3.5 Plus?

Before diving into free access, here is what makes Qwen 3.5 Plus worth your attention:

• Strong coding performance -- Outperforms many proprietary models on HumanEval, MBPP, and LiveCodeBench benchmarks
• 128K context window -- Feed entire repositories, long documents, or multi-turn conversations without truncation
• Multilingual support -- Deep understanding of 29+ languages, with particular strength in Chinese and English
• Efficient architecture -- MoE (Mixture of Experts) design delivers high throughput at lower compute cost

Free Access Method 1: DashScope Free Tier

Alibaba offers a free tier through its DashScope platform. New accounts receive complimentary token credits that refresh periodically.

Setup

1. Create an account at DashScope
2. Navigate to the API Keys section and generate a key
3. Use the OpenAI-compatible endpoint

from openai import OpenAI

client = OpenAI(
    api_key="your-dashscope-api-key",
    base_url="https://dashscope.aliyuncs.com/compatible-mode/v1"
)

response = client.chat.completions.create(
    model="qwen-plus",
    messages=[
        {"role": "system", "content": "You are an expert Python developer."},
        {"role": "user", "content": "Write a binary search function with type hints."}
    ],
    temperature=0.7
)

print(response.choices[0].message.content)

The DashScope free tier is solid for experimentation, but quotas can be limiting for production workloads.

Free Access Method 2: Hypereal AI (35 Free Credits)

Hypereal AI provides access to Qwen 3.5 Plus through an OpenAI-compatible API. Every new account gets 35 free credits with no credit card required.

Python Example

from openai import OpenAI

client = OpenAI(
    api_key="your-hypereal-api-key",
    base_url="https://hypereal.tech/api/v1"
)

response = client.chat.completions.create(
    model="qwen-3.5-plus",
    messages=[
        {"role": "system", "content": "You are a senior software engineer."},
        {"role": "user", "content": "Refactor this function to use async/await and add error handling."}
    ],
    max_tokens=2048,
    temperature=0.7
)

print(response.choices[0].message.content)

TypeScript Example

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "your-hypereal-api-key",
  baseURL: "https://hypereal.tech/api/v1",
});

async function askQwen(prompt: string): Promise<string> {
  const response = await client.chat.completions.create({
    model: "qwen-3.5-plus",
    messages: [
      { role: "system", content: "You are a helpful coding assistant." },
      { role: "user", content: prompt },
    ],
    max_tokens: 2048,
    temperature: 0.7,
  });

  return response.choices[0].message.content ?? "";
}

const answer = await askQwen("Write a REST API with Express and Zod validation.");
console.log(answer);

Streaming Responses

For real-time output, use streaming:

from openai import OpenAI

client = OpenAI(
    api_key="your-hypereal-api-key",
    base_url="https://hypereal.tech/api/v1"
)

stream = client.chat.completions.create(
    model="qwen-3.5-plus",
    messages=[
        {"role": "user", "content": "Explain how B-trees work, with a Python implementation."}
    ],
    stream=True
)

for chunk in stream:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")
