## Downloading using huggingface-cli
If you do not have hugginface-cli installed:
```
pip install -U "huggingface_hub[cli]"
```
Download the specific file you want:
```
huggingface-cli download legraphista/reader-lm-0.5b-IMat-GGUF --include "reader-lm-0.5b.Q8_0.gguf" --local-dir ./
```
If the model file is big, it has been split into multiple files. In order to download them all to a local folder, run:
```
huggingface-cli download legraphista/reader-lm-0.5b-IMat-GGUF --include "reader-lm-0.5b.Q8_0/*" --local-dir ./
# see FAQ for merging GGUF's
```

## Inference

### Simple chat template
```
<|im_start|>system
You are a helpful assistant.<|im_end|>
<|im_start|>user
{user_prompt}<|im_end|>
<|im_start|>assistant
{assistant_response}<|im_end|>
<|im_start|>user
{next_user_prompt}<|im_end|>

```

### Chat template with system prompt
```
<|im_start|>system
{system_prompt}<|im_end|>
<|im_start|>user
{user_prompt}<|im_end|>
<|im_start|>assistant
{assistant_response}<|im_end|>
<|im_start|>user
{next_user_prompt}<|im_end|>

```

### Llama.cpp
```
llama.cpp/main -m reader-lm-0.5b.Q8_0.gguf --color -i -p "prompt here (according to the chat template)"
```

## FAQ

### Why is the IMatrix not applied everywhere?
According to [this investigation](https://www.reddit.com/r/LocalLLaMA/comments/1993iro/ggufs_quants_can_punch_above_their_weights_now/), it appears that lower quantizations are the only ones that benefit from the imatrix input (as per hellaswag results). 

### How do I merge a split GGUF?
1. Make sure you have `gguf-split` available
    - To get hold of `gguf-split`, navigate to https://github.com/ggerganov/llama.cpp/releases
    - Download the appropriate zip for your system from the latest release
    - Unzip the archive and you should be able to find `gguf-split`
2. Locate your GGUF chunks folder (ex: `reader-lm-0.5b.Q8_0`)
3. Run `gguf-split --merge reader-lm-0.5b.Q8_0/reader-lm-0.5b.Q8_0-00001-of-XXXXX.gguf reader-lm-0.5b.Q8_0.gguf`
    - Make sure to point `gguf-split` to the first chunk of the split.
