Qwen3.6 Plus Preview

Alibaba · 2026-03-30

Qwen3.6 Plus Preview was a text-only OpenRouter endpoint with mandatory reasoning, published as `qwen/qwen3.6-plus-preview` on March 30, 2026. It appeared three days before Alibaba officially launched the multimodal `qwen3.6-plus`; Atlas retains the preview as a benchmark entry because no Alibaba source establishes that the two endpoints used the same artifact.
