Qwen3.8-Flash-Next (125B-A6B)

Experimental vision-language MoE whose text backbone combines Gated DeltaNet, micro-block QSA, four-branch gated residuals, and n-gram embeddings; the figure omits the vision encoder and MTP head.

Key detail

Replaces full attention with micro-block QSA while using four gated residual branches and a 20M-entry n-gram embedding at layer 2.
