The ggml‑org/llama.cpp project released a new version on 2026‑11‑13. The update adds a TOP_K_MASK operation to the Vulkan GPU backend, fixes a barrier issue for that mask, and declares the function in the common header. The changes were made with assistance from Claude Opus 5.5.
Why it matters
GPU users can now apply top‑k masking during inference, giving finer control over token selection.
