I Used the 158K-Download Reasoning Model via API — Here's the 3-Line Code

A model called Qwen3.5-9B-Claude-4.6-Opus-Reasoning-Distilled just hit 158K+ downloads on HuggingFace. Developers are obsessed because it gives you Claude-level reasoning in a 9B parameter model.

But running GGUF locally means downloading 5-8GB, setting up llama.cpp, and managing GPU resources. There's a better way.

Access via NexaAPI — No GPU Needed

# pip install nexaapi | https://pypi.org/project/nexaapi/
from nexaapi import NexaAPI

client = NexaAPI(api_key='YOUR_API_KEY')
# Sign up: https://nexa-api.com | RapidAPI: https://rapidapi.com/user/nexaquency

response = client.chat.completions.create(
    model='qwen3.5-9b-claude-reasoning',
    messages=[
        {"role": "system", "content": "Think step by step before answering."},
        {"role": "user", "content": "Analyze the tradeoffs of microservices vs monolith for a 3-person startup."}
    ],
    temperature=0.6,
    max_tokens=1024
)

print(response.choices[0].message.content)
# Full chain-of-thought reasoning + recommendation
# Cost: ~$0.003/call

JavaScript Version

// npm install nexaapi | https://npmjs.com/package/nexaapi
import NexaAPI from 'nexaapi';

const client = new NexaAPI({ apiKey: 'YOUR_API_KEY' });
// Sign up: https://nexa-api.com | RapidAPI: https://rapidapi.com/user/nexaquency

const response = await client.chat.completions.create({
  model: 'qwen3.5-9b-claude-reasoning',
  messages: [
    { role: 'system', content: 'Think step by step before answering.' },
    { role: 'user', content: 'What is the time complexity of quicksort? Explain step by step.' }
  ],
  temperature: 0.6,
  maxTokens: 1024
});

console.log(response.choices[0].message.content);
// Cost: ~$0.003/call

Why This Model?

The model distills 14,000+ Claude 4.6 Opus reasoning samples into Qwen3.5-9B. You get:

• Structured chain-of-thought reasoning
• Efficient 9B parameter size
• No GPU required via NexaAPI
