# granite-4.2-8B GGUF

GGUF conversions of [ibm-granite/granite-4.2-8b](https://huggingface.co/ibm-granite/granite-4.2-8b) for [llama.cpp](https://github.com/ggml-org/llama.cpp) at 16-bit, 8-bit and 4-bit precision.

## Files

| File | Precision | Size |
|---|---|---|
| `granite-4.2-8b-BF16.gguf` | BF16 (16-bit, lossless from source) | 17.6 GB |
| `granite-4.2-8b-Q8_0.gguf` | Q8_0 (8-bit, 8.50 bits per weight) | 9.3 GB |
| `granite-4.2-8b-Q4_K_M.gguf` | Q4_K_M (4-bit, 4.86 bits per weight) | 5.3 GB |

## Usage

```bash
# Chat server with Granite's embedded chat template (tool calling and thinking)
llama-server -hf webAI-Official/granite-4.2-8B:Q4_K_M --jinja

# Interactive chat
llama-cli -hf webAI-Official/granite-4.2-8B:Q8_0
```

Thinking is on by default in the chat template. Pass `--chat-template-kwargs '{"enable_thinking": false}'` to `llama-server` to turn it off.

## How these files were made

1. The source safetensors (bf16) were converted with llama.cpp `b9770`:
   `convert_hf_to_gguf.py ibm-granite/granite-4.2-8b --outtype bf16`
2. Q8_0 and Q4_K_M were each quantized directly from the BF16 file with `llama-quantize`. No importance matrix was used.

## Performance

Measured with `llama-bench` (llama.cpp `b9770`, Metal) on an Apple M5 Pro with 24 GB of memory:

| File | Prompt processing, 512 tokens (tok/s) | Generation, 128 tokens (tok/s) |
|---|---|---|
| BF16 | 834 | 15.3 |
| Q8_0 | 1080 | 29.1 |
| Q4_K_M | 1051 | 47.8 |

On a 24 GB machine, BF16 does not fit in GPU memory with llama.cpp's default context size. Use a smaller context, such as `-c 2048`, or choose Q8_0.

## License

Apache 2.0, the same as the base model. See [ibm-granite/granite-4.2-8b](https://huggingface.co/ibm-granite/granite-4.2-8b) for the model's details, intended use and limitations.
