Qwen3.5
Agentic-era flagship: open 397B-A17B MoE on hybrid linear attention, closed Plus tier.
About
Qwen3.5 launched February 16, 2026 for what Alibaba calls the agentic AI era. The open Qwen3.5-397B-A17B activates 17B of 397B parameters on a hybrid design fusing Gated DeltaNet linear attention with sparse MoE routing, handling text, image, and video with 254K default context.
Alibaba says it runs 60% cheaper with 8x the large-workload throughput of its predecessor, with 201-language support and visual agentic capabilities for operating mobile and desktop apps. A closed Qwen3.5-Plus hosted tier offers 1M context for enterprises; smaller on-device variants arrived March 2, 2026.
