## AI4Chem/CHEMLLM-2b-1_5 - GGUF

This repo contains GGUF format model files for [AI4Chem/CHEMLLM-2b-1_5](https://huggingface.co/AI4Chem/CHEMLLM-2b-1_5).

The files were quantized using machines provided by [TensorBlock](https://tensorblock.co/), and they are compatible with llama.cpp as of [commit b4011](https://github.com/ggerganov/llama.cpp/commit/a6744e43e80f4be6398fc7733a01642c846dce1d).

## Downloading instruction

### Command line

Firstly, install Huggingface Client

```shell
pip install -U "huggingface_hub[cli]"
```

Then, downoad the individual model file the a local directory

```shell
huggingface-cli download tensorblock/CHEMLLM-2b-1_5-GGUF --include "CHEMLLM-2b-1_5-Q2_K.gguf" --local-dir MY_LOCAL_DIR
```

If you wanna download multiple model files with a pattern (e.g., `*Q4_K*gguf`), you can try:

```shell
huggingface-cli download tensorblock/CHEMLLM-2b-1_5-GGUF --local-dir MY_LOCAL_DIR --local-dir-use-symlinks False --include='*Q4_K*gguf'
```
