TinyLlama 1.1B Chat - Big-Endian GGUF

This is a big-endian version of TinyLlama-1.1B-Chat-v1.0 in GGUF format, optimized for IBM AIX on POWER architecture.

Model Details

• Base Model: TinyLlama 1.1B Chat v1.0
• Format: GGUF (Q4_K_M quantization)
• Endianness: Big-endian (IBM Power Systems)
• Size: 638 MB
• License: Apache 2.0

Usage

This model is designed for use with llama-aix, a port of llama.cpp for IBM AIX.

# Download model
wget https://huggingface.co/librepower/tinyllama-1.1b-chat-be/resolve/main/tinyllama-1.1b-q4_k_m-be.gguf

# Run inference on AIX
./llama-simple -m tinyllama-1.1b-q4_k_m-be.gguf -n 128 -p "Hello, world!"

Performance

On IBM POWER9 (16 cores, 128GB RAM):

• Speed: ~18 tokens/second
• Memory: ~800 MB RAM

Why Big-Endian?

IBM Power Systems use big-endian byte order, while most modern systems use little-endian. This model has been converted using llama.cpp's endianness conversion tool to run natively on AIX without runtime conversion overhead.

Conversion

This model was converted from the original little-endian GGUF using:

./llama-gguf-split --convert-be model.gguf model-be.gguf
