## Introduction for Model Merging
**Model Merging**, also known as model fusion, is an effective technique that merges the parameters of multiple separate models with different capabilities to build a universal model without needing access to the
original training data or expensive computation.
There are bunch of methods, we can use to merge the capabilities of different models (supported by [mergekit](https://github.com/arcee-ai/mergekit)) including:

### Introduction for SLERP Merging
**Spherical Linear Interpolation (SLERP)** is a method used to smoothly interpolate between two vectors. It maintains a constant rate of change and preserves the geometric properties of the spherical space in which the vectors reside.
SLERP is currently the *most-popular merging method*, preffered over traditional methods because instead of dealing with straight-lines, the interpolation occurs on the surface of a sphere, and it has achieved improved performance to very diverse task.
> But SLERP is limited to combining only **two models at a time**, although its possible to hierarchically combine multiple models, as shown in [Mistral-7B-Merge-14-v0.1](https://huggingface.co/EmbeddedLLM/Mistral-7B-Merge-14-v0.1).

from transformers import AutoTokenizer
import transformers
import torch
model = "yuvraj17/Llama3-8B-abliterated-Spectrum-slerp"
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"])
```
