llama.cpp b10660 adds Qwen3.8-Flash-Next (qwen4exp) architecture: hyper-connections, gated delta net layers, MoE, PLE n-gram embedding
llama.cpp
Released Aug 27, 2026 (PR #27742). Adds Qwen3.8-Flash-Next (qwen4exp) architecture support including hyper-connections, gated delta net layers, MoE, PLE n-gram embedding, and an optional indexer key cache in llama_memory_hybrid. Companion builds b10656-b10659 add quantize working-memory cap, DFlash2 speculative decoding with local convolution, OpenCL MoE kernels (q4_0_q8_1 and mxfp4_q8_1), bundled HIP runtime DLLs on Windows ROCm, and a CI change to build only the ggml-hip backend on windows-rocm.
Why it matters
First inference runtime outside Qwen's own reference impl to natively run Qwen3.8-Flash-Next — the experimental Qwen4-architecture preview covered in the 2026-08-27 digest — making the new architecture immediately runnable on Apple Silicon, ROCm, CUDA, and CPU.
