StableLM-2-Zephyr-1.6B Q4_K_M — Big-Endian

Big-endian GGUF of stabilityai/stablelm-2-zephyr-1_6b 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.

Model Details

Field	Value
Parameters	1.6B
Architecture	StableLM transformer
Quantization	Q4_K_M
Context length	4,096 tokens
File	`stablelm-2-zephyr-1.6b-Q4_K_M-be.gguf` (983 MB)
Endianness	Big-endian
Source	stabilityai/stablelm-2-zephyr-1_6b

Performance on IBM POWER9 (AIX 7.3)

Tested at 16 threads, SMT-2:

Generation: 15.02 tok/s
Prompt processing: 2.12 tok/s

Quick Start (AIX)

git clone https://gitlab.com/librepower/llama-aix.git
cd llama-aix
./scripts/fetch_upstream.sh && ./scripts/build_aix_73.sh
wget https://huggingface.co/librepowerai/StableLM-2-Zephyr-1.6B-Q4_K_M-BE/resolve/main/stablelm-2-zephyr-1.6b-Q4_K_M-be.gguf
