This record represents the Qwen3.5-Plus line at its newest dated snapshot, qwen3.5-plus-2026-04-20, which Alibaba Cloud Model Studio serves in its Singapore and Beijing regions with text, image, and video input and 1M context. The undated qwen3.5-plus model still resolves to the February 15, 2026 snapshot, which this record does not cover. That snapshot, the Qwen3.5-397B-A17B open weights that Alibaba calls Qwen3.5-Plus's open counterpart, the Qwen3.5-Flash line, later Qwen generations, and independent hosts are separate boundaries.
