While Western labs guard their best models behind APIs, Alibaba has spent three years doing the opposite — pouring frontier-grade models into the open under a permissive licence. Qwen (or Tongyi Qianwen) is the result: the largest, most complete open-weight model family in existence, paired with a free chat app at chat.qwen.ai. It’s a staple of the open-source community, genuinely strong at coding and reasoning, and astonishing on languages. It also carries the same privacy and censorship questions as any China-hosted AI. This review covers the consumer Qwen Chat app and Alibaba’s open Qwen models; the Alibaba Qwen API and model platform are reviewed separately.

The models in 2026

Qwen’s defining feature is breadth. The Qwen3 family alone spans eight models from 0.6B to 235B parameters, all released under the open Apache 2.0 licence, running on everything from a phone to an H100 cluster. The flagship Qwen3-235B sits neck-and-neck with the best open-weight generalists, Qwen3-Coder (480B) matches Claude Sonnet on agentic coding, and Qwen3.5 pushed the family to 397B parameters with support for over 200 languages.

The newest release, Qwen3.7-Max (May 2026), is pitched as an “agent frontier” model built for long-horizon, tool-heavy tasks with a one-million-token context. Notably, it’s API-only — not open-weight, a shift from Alibaba’s open tradition, while the open line continues at Qwen3.6 and below. Qwen Chat lets you use the latest preview models free, with a thinking mode for harder problems.

Features

Chat, thinking & search

Qwen Chat covers the essentials well: conversational chat, a reasoning “thinking” mode, web search for current information, and document processing for files you upload. Answers are strong on technical, mathematical and coding questions.

Vision, images & artifacts

The app handles image and video understanding, generates images, and supports artifacts — interactive outputs you can preview and refine — plus tool use. It’s a more multimodal experience than some open-source rivals offer out of the box.

Multilingual & open weights

Qwen’s standout is languages: the latest models support over 200, making it one of the best choices on the planet for non-English work. And because most Qwen models are open-weight, you can download them from Hugging Face and run them privately on your own hardware.

Pricing in 2026

Qwen is among the cheapest routes to a capable model anywhere, and the chat app is free.

For developers, the combination of free open weights and a near-free API is hard to beat. For everyday users, the free chat app is generous — the main limits are rate caps and, as below, the privacy and censorship trade-offs of a China-hosted service.

Pros and cons

Where it falls short

As with any China-hosted assistant, the first concern is data privacy. The Qwen Chat app is run by Alibaba, so your conversations are stored in China and subject to Chinese law. For general, non-sensitive work that’s fine; for confidential, client or personal data, it isn’t the right tool. The saving grace is the open weights — self-host a Qwen model and the data never leaves your hardware, which is exactly why so many privacy-conscious developers use Qwen this way.

The second is censorship: in line with Chinese content rules, Qwen declines or deflects on politically sensitive subjects, which matters if you value unfiltered inquiry. Beyond those, there are smaller caveats. Alibaba’s newest flagship has gone closed, a step back from its open ethos; the consumer Qwen Chat app is less refined and far less known outside China and the developer world; its English prose is good but not quite at the level of the best Western models; and the rapid-fire versioning (3.5 to 3.6 to 3.7 in months) makes it hard to track what’s current. None of this dims Qwen’s value as an open-weight powerhouse — it just defines who should use it, and how.

Scorecard

How Qwen scores across what matters, averaging to 7.4/10:

Verdict

Qwen is the most generous open-source story in AI, and for the right person it’s outstanding. If you build on open models, self-host for privacy, work across many languages, or want frontier-adjacent coding for almost nothing, Qwen is one of the best options in the world — and the free chat app is a capable bonus. Alibaba’s open-weight strategy has genuinely shaped the whole field.

It scores 7.4 because the trade-offs are real: the hosted app’s data goes to China, sensitive topics are censored, the newest flagship has closed up, and the consumer experience trails the polished Western apps. Use it freely for non-confidential technical and multilingual work — ideally self-hosted — and keep confidential data on a tool you trust.
