Qwen3-Coder-Next - regolo.ai

Qwen3-Coder-Next is an open-weight causal language model designed specifically for coding agents and local development. It uses an 80B sparse MoE architecture with only 3B activated parameters, aiming to deliver strong coding performance at much lower inference cost than larger active-parameter models. Qwen describes it as strong in long-horizon reasoning, complex tool usage, and recovery from execution failures, which makes it suitable for real-world agentic coding workflows.

How to get started

pip install requestsCode language: Bash (bash)

import requests


api_url = "https://api.regolo.ai/v1/chat/completions"
headers = {
    "Content-Type": "application/json",
    "Authorization": "Bearer YOUR_REGOLO_KEY"
}
data = {
  "model": "qwen3-coder-next",
  "messages": [
    {
      "role": "user",
      "content": "Write a Python function to calculate the factorial of a number using recursion."
    }
  ]
}

response = requests.post(api_url, headers=headers, json=data)
print(response.json())Code language: Python (python)
