# AmberSafe


We present AmberSafe, a safety-finetuned instruction model using [LLM360/AmberChat](https://huggingface.co/LLM360/AmberChat) as the base.

## Model Description

- **Model type:** Language model with the same architecture as LLaMA-7B
- **Language(s) (NLP):** English
- **License:** Apache 2.0
- **Resources for more information:**
  - [Metrics](https://github.com/LLM360/Analysis360)
  - [Fully processed Amber pretraining data](https://huggingface.co/datasets/LLM360/AmberDatasets)
  - [Finetuning Code](https://github.com/LLM360/amber-train/tree/main/finetune/ambersafe)


# Loading AmberSafe 

```python
import torch
from transformers import LlamaTokenizer, LlamaForCausalLM

tokenizer = LlamaTokenizer.from_pretrained("LLM360/AmberSafe")
model = LlamaForCausalLM.from_pretrained("LLM360/AmberSafe")

#template adapated from fastchat
template= "###Human: {prompt}\n###Assistant:"

prompt = "How do I mount a tv to drywall safely?"

input_str = template.format(prompt=prompt)
input_ids = tokenizer(input_str, return_tensors="pt").input_ids
outputs = model.generate(input_ids, max_length=1000)
print(tokenizer.batch_decode(outputs[:, input_ids.shape[1]:-1])[0].strip())
```

Alternatively, you may use [FastChat](https://github.com/lm-sys/FastChat):
```bash
python3 -m fastchat.serve.cli --model-path LLM360/AmberSafe
```

# AmberSafe Finetuning Details

## DataMix
| Subset      | Number of rows |  License   |
| ----------- | ----------- | ----------- |
| [PKU-Alignment/PKU-SafeRLHF](https://huggingface.co/datasets/PKU-Alignment/PKU-SafeRLHF)    | 330k        | cc-by-nc-4.0 |
| Total | 330k |  |

## Data Preprocessing
We filtered the dataset by selecting all data samples with different boolean values in `is_response_0_safe` and `is_response_1_safe`. This would make sure that for each pair in the preference dataset, the chosen text is safe and the rejected one is unsafe.

## Method
We followed the instructions in the [dpo repo](https://github.com/eric-mitchell/direct-preference-optimization) to finetune this model.

1. Run supervised fine-tuning (SFT) on the dataset(s) of interest.
2. Run preference learning on the model from step 1, using preference data (ideally from the same distribution as the SFT examples).

# Using Quantized Models with Ollama

Please follow these steps to use a quantized version of AmberSafe on your personal computer or laptop:

1. First, install Ollama by following the instructions provided [here](https://github.com/jmorganca/ollama/tree/main?tab=readme-ov-file#ollama). Next, create a quantized version of AmberSafe model (say ambersafe.Q8_0.gguf for 8 bit quantized version) following instructions [here](https://github.com/jmorganca/ollama/blob/main/docs/import.md#manually-converting--quantizing-models). Alternatively, you can download the 8bit quantized version that we created [ambersafe.Q8_0.gguf](https://huggingface.co/LLM360/AmberSafe/resolve/Q8_0/ambersafe.Q8_0.gguf?download=true)

2. Create an Ollama Modelfile locally using the template provided below:
```
FROM ambersafe.Q8_0.gguf

TEMPLATE """{{ .System }}
USER: {{ .Prompt }}
ASSISTANT:
"""
SYSTEM """A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions.
"""
PARAMETER stop "USER:"
PARAMETER stop "ASSISTANT:"
PARAMETER repeat_last_n   0
PARAMETER num_ctx         2048
PARAMETER seed            0
PARAMETER num_predict    -1
```
Ensure that the FROM directive points to the created checkpoint file.

3. Now, you can proceed to build the model by running:
```bash
ollama create ambersafe -f Modelfile
```
4. To run the model from the command line, execute the following:
```bash
ollama run ambersafe
```
You need to build the model once and can just run it afterwards.
