# Llama-3-2B-Base
A slimmed-down, third-party adaptation of the Llama 3 model with only 2 billion parameters.
**Important**: This project is not affiliated with Meta.
---
## Overview
Llama-3-2B-Base is a reduced version of the popular Llama 3 models, specifically designed to bring the power of LLMs (Large Language Models) to environments with limited computational resources. This model offers a balance between performance and resource usage, serving as an efficient alternative for users who cannot leverage the larger, resource-intensive versions from Meta.
## Model Developers
This version has been developed independently and is not associated with Meta.
## Input/Output
- **Input**: Text only.
- **Output**: Generates text and code only.
## Model Architecture
Llama-3-2B is an auto-regressive language model using an optimized transformer architecture. It employs supervised fine-tuning (SFT) and reinforcement learning with human feedback (RLHF) to enhance alignment with human preferences for helpfulness and safety.
## Intended Use
- **Use Cases**: Suitable for both commercial and research use in English, capable of assistant-like chat and a variety of natural language generation tasks.
- **Out-of-Scope**: Any use that violates applicable laws or regulations (including trade compliance laws), or the Acceptable Use Policy.
## Usage Instructions
### Use with transformers
You can leverage the `transformers` library to run inference.
#### Transformers Pipeline
```python
import transformers
import torch
model_id = "andrijdavid/Llama-3-2B-Base"
pipeline = transformers.pipeline(
"text-generation", model=model_id,
model_kwargs={"torch_dtype": torch.bfloat16},
device_map="auto"
)
messages = [
{"role": "system", "content": "You are a pirate chatbot who always responds in pirate speak!"},
{"role": "user", "content": "Who are you?"}
]
terminators = [
pipeline.tokenizer.eos_token_id,
pipeline.tokenizer.convert_tokens_to_ids("<|eot_id|>")
]
outputs = pipeline(
messages, max_new_tokens=256,
eos_token_id=terminators,
do_sample=True, temperature=0.6, top_p=0.9
)
print(outputs[0]["generated_text"][-1])
```
## Hardware and Software Considerations
Llama-3-2B is designed to run efficiently on mid-tier hardware, significantly lowering the entry barrier for using advanced language models.
## Ethical Considerations and Limitations
Llama-3-2B, like any LLM, is susceptible to generating biased or inappropriate outputs. Developers must evaluate and fine-tune the model to ensure safety and suitability for their specific use cases. |
