Qwen 3.5 Small
Alibaba's compact multimodal AI model family (0.8B to 9B parameters) delivering surprisingly strong performance for on-device applications, edge computing, and lightweight agent tasks.
What is Qwen 3.5 Small?
The Qwen 3.5 Small Model Series, launched by Alibaba's Qwen team on March 2, 2026, is a family of four models ranging from 0.8B to 9B parameters built for on-device and edge deployment. All models share the same Qwen 3.5 architecture with native multimodal support for both text and images in a single model. The series includes architectural upgrades and scaled reinforcement learning from the larger Qwen 3.5 models. The 0.8B and 2B variants target edge devices and mobile, the 4B model serves as a strong multimodal base for lightweight agents, and the 9B model closes the gap with much larger models. Available on Hugging Face Hub and ModelScope under open-source licenses.
