Qwen is the family of AI models built by Alibaba, one of China's largest technology companies, through its Alibaba Cloud division. In Chinese the brand is known as Tongyi Qianwen (通义千问). Over the past few years Qwen has grown from a research project into one of the most influential model families in the world, and Alibaba has kept releasing new versions at a rapid pace, with Qwen 3.8 Max (released August 2026) as the current flagship.
Qwen comes in two flavors. The hosted "Max" models, like Qwen 3.8 Max, are Alibaba's most capable and are served through Qwen Cloud, Alibaba's API (this is the Qwen you get inside Fello AI). Alongside them, Alibaba publishes open weights: smaller Qwen models such as Qwen3.8-27B under the permissive Apache 2.0 license, and, for the first time with Qwen3.8, a Max-class model, the 2.4-trillion-parameter Qwen3.8-2.4T-A95B, under its own Qwen3.8-Max License. Those open releases, published on Hugging Face, ModelScope, and Kaggle, have made Qwen the world's most-downloaded and most-derived open model family, with hundreds of thousands of fine-tuned models built on top of it.
For everyday work, Qwen is a strong all-rounder. Alibaba has listed support for 201 languages and dialects since Qwen3.5, the foundation Qwen3.8 is built on, which makes it one of the most capable multilingual models available, and dedicated Qwen-Coder variants make it a genuinely good coding assistant. A hybrid "thinking / non-thinking" mode lets it toggle step-by-step reasoning on or off depending on the task.
Qwen vs Qwen 3.8 Max: Qwen is the model family (Tongyi Qianwen) from Alibaba. Qwen 3.8 Max is the current flagship, the hosted version you use through Alibaba's Qwen Cloud API and Qwen Studio. It is built on Qwen3.8-2.4T-A95B, whose weights Alibaba released in August 2026 under its own Qwen3.8-Max License; the hosted Max adds vision input, a 1M-token default context, and built-in tools. Smaller open Qwen models such as Qwen3.8-27B ship under the Apache 2.0 license, so anyone can download, modify, and self-host those. In Fello AI, Qwen queries are routed through secure US-based servers, not through Alibaba's own infrastructure.
