Qwen3.5-4B
Qwen3.5-4B is Alibaba Cloud's compact multimodal foundation model with 4B parameters, released February 2026. It uses a hybrid architecture combining Gated Delta Networks and Gated Attention in an 8×(3×DeltaNet→FFN→1×Attention→FFN) pattern. It achieves MMLU-Pro (79.1%), GPQA Diamond (76.2%), HMMT benchmarks (74%/77%), and strong vision-language scores. Features unified vision-language capabilities, 262k native context (extensible to 1M), multi-token prediction training, and delivers efficient performance across reasoning, coding, multimodal understanding, and multilingual tasks covering 201 languages.
