# mix-llama-3-8B-inst-line

mix-llama-3-8B-inst-line is a merge of the following models using [LazyMergekit](https://colab.research.google.com/drive/1obulZ1ROXHjYLn6PPZJwRR6GzgQogxxb?usp=sharing):
* [NousResearch/Meta-Llama-3-8B-Instruct](https://huggingface.co/NousResearch/Meta-Llama-3-8B-Instruct)

## 🧩 Configuration

```yaml
dtype: bfloat16
merge_method: linear
slices:
 - sources:
      - layer_range: [0, 16] # Assuming the first half of the model is more general and can be reduced more
        model: NousResearch/Meta-Llama-3-8B-Instruct
        parameters:
          weight: 0.5 # Reduce the weight of the first half to make room for the second half
      - layer_range: [16, 32] # Assuming the second half of the model is more specialized and can be reduced less
        model: NousResearch/Meta-Llama-3-8B-Instruct
        parameters:
          weight: 0.5 # Maintain the weight of the second half

```

## 💻 Usage

```python
!pip install -qU transformers accelerate

from transformers import AutoTokenizer
import transformers
import torch

model = "JoPmt/mix-llama-3-8B-inst-line"
messages = [{"role": "user", "content": "What is a large language model?"}]

tokenizer = AutoTokenizer.from_pretrained(model)
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
pipeline = transformers.pipeline(
    "text-generation",
    model=model,
    torch_dtype=torch.float16,
    device_map="auto",
)

outputs = pipeline(prompt, max_new_tokens=256, do_sample=True, temperature=0.7, top_k=50, top_p=0.95)
print(outputs[0]["generated_text"])
