A 27B-parameter hybrid decoder: three Gated DeltaNet (linear attention) layers for every gated full-attention layer, zero-centered RMS norms, SwiGLU, and an untied output head; the text model of Qwen3.8-27B, without its vision tower.
No sample has been recorded for Qwen3.8 27B yet. What it produces, next to the reference stack's answer, will appear here once the benchmark harness has run it.
