This repository contains models that have been converted to the GGUF format with various quantizations from an IBM Granite .safetensors model.

Please reference the base model's full model card here: https://huggingface.co/ibm-granite/granite-4.1-30b

Merging the `.bf16` model

The bf16 model had to be split into multiple files to accommodate single file size restrictions using the llama-gguf-split tool, with its default --split settings, which can be built from the ggml-org/llama.cpp project.

Use the following command to merge the split files which points to the first file in the sequence:

llama-gguf-split --merge granite-4.1-30b-bf16-00001-of-00005.gguf granite-4.1-30b-bf16.gguf

The remaining split filenames are inferred by the tool based upon the 00001-of-0000x naming convention.
