llama.cpp adds BF16 support for RMS_NORM on CPU and CUDA

The open‑source Llama inference library now handles BF16 precision in its RMS_NORM operation, with binaries for macOS, iOS and Linux.

The ggml‑org team released llama.cpp version b12366 on 2026‑11‑13. The update adds BF16 (a 16‑bit floating‑point format) support to the RMS_NORM layer for both CPU and CUDA back‑ends. A single helper now launches the F32/BF16 RMS_NORM kernels. Pre‑built binaries for macOS Apple Silicon, Intel, iOS, and several Ubuntu variants are available for download.

Why it matters

Developers can run Llama models faster on hardware that prefers BF16, lowering memory use without losing much accuracy.
