# Llama3.1-SEP-Chat

This model is a LoRA finetune of meta-llama/Meta-Llama-3.1-8B trained on multi-turn philosophical conversations. It is designed to engage in philosophical discussions in a conversational yet rigorous manner, maintaining academic standards while being accessible.

## Model description

The model was trained using the TRL (Transformer Reinforcement Learning) library's chat template, enabling it to handle multi-turn conversations in a natural way. It builds upon the capabilities of its predecessor [Llama3-stanford-encyclopedia-philosophy-QA](https://huggingface.co/ruggsea/Llama3-stanford-encyclopedia-philosophy-QA) but extends it to handle more interactive, back-and-forth philosophical discussions.

### Chat Format
The model uses the standard chat format with roles:
```python
<|system|>
{{system_prompt}}
<|user|>
{{user_message}}
<|assistant|>
{{assistant_response}}
```

### Training Details
The model was trained with the following system prompt:
```
You are an expert and informative yet accessible Philosophy university professor. Students will engage with you in philosophical discussions. Respond to their questions and comments in a correct and rigorous but accessible way, maintaining academic standards while fostering understanding.
```

### Training hyperparameters

The following hyperparameters were used during training:
- Learning rate: 2e-5
- Train batch size: 1
- Gradient accumulation steps: 4
- Effective batch size: 4
- Optimizer: paged_adamw_8bit
- LR scheduler: cosine with warmup
- Warmup ratio: 0.03
- Training epochs: 5
- LoRA config:
  - r: 256
  - alpha: 128
  - Target modules: all-linear
  - Dropout: 0.05

### Framework versions
- PEFT 0.10.0
- Transformers 4.40.1
- PyTorch 2.2.2+cu121
- TRL latest
- Datasets 2.19.0
- Tokenizers 0.19.1

## Intended Use
This model is designed for:
- Multi-turn philosophical discussions
- Academic philosophical inquiry
- Teaching and learning philosophy
- Exploring philosophical concepts through dialogue

## Limitations
- The model should not be used as a substitute for professional philosophical advice or formal philosophical education
- While the model aims to be accurate, its responses should be verified against authoritative sources
- The model may occasionally generate plausible-sounding but incorrect philosophical arguments
- As with all language models, it may exhibit biases present in its training data

## License
This model is subject to the Meta Llama 2 license agreement. Please refer to Meta's licensing terms for usage requirements and restrictions.

## How to use
Here's an example of how to use the model:

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

# Load model and tokenizer
model = AutoModelForCausalLM.from_pretrained("ruggsea/Llama3.1-SEP-Chat")
tokenizer = AutoTokenizer.from_pretrained("ruggsea/Llama3.1-SEP-Chat")


# Example conversation
messages = [
    {"role": "user", "content": "What is the difference between ethics and morality?"}
]

# Format prompt using chat template
prompt = tokenizer.apply_chat_template(
    messages,
    add_generation_prompt=True,
    tokenize=False
)

# Generate response
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=512)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
```
