# Model Summary
<img src="llama-3-6B icon.jpeg" width="500" alt="Llama-3-6B"/>

Introducing the world's first Llama-3 base model with 6B parameters. This model is a pretrained version of [prince-canuma/Llama-3-6B-v0](https://huggingface.co/prince-canuma/Llama-3-6B-v0), which was created from Meta-Llama-3-8B using a technique called [downcycling](https://youtube.com/playlist?list=PLDn_JsyofyfTH5_5V1MNb8UYKxMl6IMNy&si=9hcOol4KHIgWThgt) .
The model was continually pretrained on 1 billion tokens of English-only text from fineweb, achieving impressive results on the evaluation set:
- Loss: 2.4942

## Model Description

<!-- Provide a longer summary of what this model is. -->
This is the model card of a 🤗 transformers model that has been pushed on the Hub. This model card has been automatically generated.

- **Developed by:** [Prince Canuma](https://huggingface.co/prince-canuma)
- **Sponsored by:** General
- **Model type:** Llama
- **Language(s) (NLP):** [More Information Needed]
- **License:** MIT
- **Pretrained from model:** prince-canuma/Llama-3-6B-v0

### Model Sources [optional]

## Uses

<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->
You can use this model to create instruct and chat versions for various use cases such as: Coding assistant, RAG, Function Calling and more.

### Limitations 

This model inherits some of the base model's limitations and some additional ones from it's creation process, such as:
 - Limited scope for coding and math: According to benchmarks, this model needs more pretraining/finetuning on code and math data to excel at reasoning tasks.
 - Language Limitations: This model was continually pretrained on english only data. If you are planning to use it for multilingual use cases I recommend fine-tuning or continued pretraining.

## How to Get Started with the Model

Use the code below to get started with the model.

```python
from transformers import AutoModelForCausalLM, AutoConfig, AutoTokenizer

# Load model, config and tokenizer
model_name = "prince-canuma/Llama-3-6B-v0.1"
model = AutoModelForCausalLM.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)

inputs = tokenizer(
[
   "Who created Python?"
], return_tensors = "pt")

from transformers import TextStreamer
text_streamer = TextStreamer(tokenizer)
_ = model.generate(**inputs, streamer = text_streamer, max_new_tokens = 200)

```

Output:
```shell

Python is a programming language that was created by Guido van Rossum in 1991. It is a widely used language for web development, data science, and machine learning. Python is also used for creating software applications and games.
Python is a powerful language that is easy to learn and use. It has a large library of built-in functions and packages that make it easy to write code. Python is also a very popular language for web development, with many popular web frameworks such as Django and Flask being written in Python.
Python is also used for data science and machine learning. It has a large library of packages for data analysis, machine learning, and artificial intelligence. Python is also used for creating software applications and games.
Python 2 and Python 3 are two different versions of the Python language. Python 2 was the original version of the

## Training Details

### Downcycling

A technique that allows you to create new LLMs of diversa sizes from checkpoints of large pretrained models.
You take a reference model (i.e., Llama-3-8B) and copy the weights of 24 layers out of 32 layers alongside embedding and prediction heads. Then you initialize a smaller target model with 24 layers and load those pretrained weights.
This new model will most likely still output legible outputs, but for it to perform well you need continue the pretraining.




### Training Data

For continued pretrained, I extracted 1B tokens from [Huggingface's FineWeb CC-Main-2024-10](https://huggingface.co/datasets/HuggingFaceFW/fineweb#breakdown-by-dumpcrawl) slice.
