Qwen 3 by Alibaba Cloud is a comprehensive open-source LLM family featuring both dense and Mixture-of-Experts models trained on 36 trillion tokens across 119 languages. With models ranging from 0.6B to 235B parameters, it offers exceptional flexibility — from edge devices to frontier-level reasoning, with unique hybrid thinking/non-thinking modes.
For reasoning-heavy tasks, enable thinking mode:
Think step by step through this problem before giving your answer.
Given a dataset of 10,000 customer transactions, design a fraud
detection pipeline that minimizes false positives while catching
at least 95% of fraudulent transactions.
For simple, factual queries, disable thinking mode for faster responses.
Qwen excels at cross-lingual tasks:
