# Qwen

> Alibaba's Qwen models in ZeroTwo — strong multilingual, math, and coding performance across a wide capability range.

Qwen (通义千问) is Alibaba Group's family of large language models. With a wide range of models from ultra-fast flash variants to the flagship Qwen Max, Qwen covers a broad spectrum of capability and cost efficiency. Qwen models are particularly strong in Chinese, Japanese, Korean, and other Asian languages, as well as mathematics and coding.

## Strengths

**Multilingual (especially Asian languages):** Qwen models are trained with extensive multilingual data, with particularly strong performance in Chinese (Simplified and Traditional), Japanese, and Korean. For tasks in these languages, Qwen often significantly outperforms Western-focused models.

**Mathematics:** Qwen Max and Qwen3 variants perform strongly on mathematical reasoning, including algebra, calculus, statistics, and quantitative analysis.

**Coding:** Qwen models have strong coding capabilities across many programming languages, with particular strength in tasks requiring code + Chinese-language documentation or explanation.

**Cost-effective high-volume use:** Qwen Turbo and Qwen Flash offer strong capability at standard model efficiency — ideal for high-volume use cases where premium quota conservation matters.

**Image generation and editing:** Qwen provides image generation (Qwen Image) and image editing (Qwen Image Edit) models in addition to text models.

## Qwen Image Models

In addition to text generation, ZeroTwo includes Qwen's image models:

**Qwen Image:** Text-to-image generation — describe an image and Qwen generates it. Available in Studio at `/studio/images`.

**Qwen Image Edit:** Image modification — upload an existing image and describe the changes you want. Useful for iterative image refinement.

Both image models require Pro+ plan access.

<Tip>
  For Chinese-language work, try Qwen Max first — it consistently produces high-quality, natural Chinese text that closely matches how a native speaker would phrase things.
