# LocalAI speech-to-text backend, built from whisper.cpp at the exact
# commit this LocalAI release pins. whisper.cpp vendors ggml in-tree, so a
# single engine tarball suffices. Upstream's Makefile passes GGML_HIPBLAS
# for ROCm, which this ggml no longer understands (silently CPU-only);
# the eclass default GGML_HIP is the correct toggle.

# The whisper.cpp commit LocalAI v4.9.0 builds against. Source of truth:
