Alibaba · Multimodal · Released Feb 2026
Qwen3.5 397B A17B is a 397-billion-parameter multimodal model from Alibaba combining linear attention with sparse mixture-of-experts routing.
- Strengths
- The model handles extended contexts with its 262K token window and can process text and image inputs through its multimodal architecture.
- Best for
- Long-context tasks involving mixed text and visual content where parameter scale and sparse routing can improve reasoning and accuracy.
- Limitations
- Larger models increase latency compared to lighter Qwen3.5 variants, and the 262K context window is shorter than the 1 million token window offered by more recent Qwen3.6 and Qwen3.5 Plus models.
