## Prerequisites
In addition to pytorch and transformers, install required packages:
```
pip install sentencepiece
```
## Usage
To use, copy the following script:
```python
ffrom transformers import AutoModelForCausalLM, AutoTokenizer

model_id = 'mediocredev/open-llama-3b-v2-chat'
tokenizer_id = 'mediocredev/open-llama-3b-v2-chat'
tokenizer = AutoTokenizer.from_pretrained(tokenizer_id)
model = AutoModelForCausalLM.from_pretrained(model_id)

chat_history = [
    {"role": "user", "content": "Hello!"},
    {"role": "assistant", "content": "I am here."},
    {"role": "user", "content": "How many days are there in a leap year?"},
]

input_ids = tokenizer.apply_chat_template(
    chat_history, tokenize=True, add_generation_prompt=True, return_tensors="pt"
).to(model.device)
output_tokens = model.generate(
    input_ids,
    repetition_penalty=1.05,
    max_new_tokens=1000,
)
output_text = tokenizer.decode(
    output_tokens[0][len(input_ids[0]) :], skip_special_tokens=True
)

print(output_text)
# Assistant: There are 366 days in a leap year, which is one more day than the standard year.
```
## Limitations

mediocredev/open-llama-3b-v2-chat is based on LLaMA 3B v2. It can struggle with factual accuracy, particularly when presented with conflicting information or nuanced topics. Its outputs are not deterministic and require critical evaluation to avoid relying solely on its assertions. Additionally, its generative capabilities, while promising, can sometimes produce factually incorrect or offensive content, necessitating careful curation and human oversight. As an evolving model, LLaMA is still under development, and its limitations in areas like bias mitigation and interpretability are being actively addressed. By using this model responsibly and being aware of its shortcomings, we can unlock its potential while mitigating its risks.
