H2O-Danube2-1.8B-Chat Q4_K_M — Big-Endian
Big-endian GGUF of h2oai/h2o-danube2-1.8b-chat for IBM AIX and other big-endian POWER systems.
Why Big-Endian?
GGUF files store all data in little-endian. On big-endian systems (AIX, z/OS), llama.cpp detects the mismatch and fails. This pre-converted model works directly.
