# Biden Mistral Adapter

This is a LoRA adapter for the [Mistral-7B-Instruct-v0.2](https://huggingface.co/mistralai/Mistral-7B-Instruct-v0.2) model, fine-tuned to emulate Joe Biden's distinctive speaking style, discourse patterns, and policy positions.

## Model Details

- **Base Model**: [mistralai/Mistral-7B-Instruct-v0.2](https://huggingface.co/mistralai/Mistral-7B-Instruct-v0.2)
- **Model Type**: LoRA adapter (Low-Rank Adaptation)
- **LoRA Rank**: 16
- **Language**: English
- **Training Focus**: Emulation of Joe Biden's communication style and response patterns

## Intended Use

This model is designed for:
- Educational and research purposes related to political discourse and communication styles
- Interactive simulations for understanding political rhetoric
- Creative applications exploring political communication

## Training Data

This adapter was fine-tuned on two key datasets:
- [Biden tweets dataset (2007-2020)](https://www.kaggle.com/datasets/rohanrao/joe-biden-tweets)
- [Biden 2020 DNC speech dataset](https://www.kaggle.com/datasets/christianlillelund/joe-biden-2020-dnc-speech)

These datasets were processed into an instruction format:

## Training Procedure

- **Framework**: Hugging Face Transformers and PEFT
- **Optimization**: 4-bit quantization for memory efficiency
- **LoRA Configuration**:
  - `r=16`
  - `lora_alpha=64`
  - `lora_dropout=0.05`
  - Target modules: q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj
- **Training Parameters**:
  - Batch size: 4
  - Gradient accumulation steps: 4
  - Learning rate: 2e-4
  - Epochs: 3
  - Learning rate scheduler: cosine
  - Optimizer: paged_adamw_8bit
  - BF16 precision

## Limitations and Biases

- The model is designed to mimic a speaking style and may not always provide factually accurate information
- While it emulates Biden's rhetoric, it does not represent his actual views or statements
- The model may reproduce biases present in the training data
- Not suitable for production applications requiring factual accuracy without RAG enhancement

## Usage

This adapter should be applied to the Mistral-7B-Instruct-v0.2 base model:

```python
from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig
from peft import PeftModel
import torch

# Load base model with 4-bit quantization
base_model_id = "mistralai/Mistral-7B-Instruct-v0.2"
bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_compute_dtype=torch.float16,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_use_double_quant=True,
)

# Load model and tokenizer
model = AutoModelForCausalLM.from_pretrained(
    base_model_id,
    quantization_config=bnb_config,
    device_map="auto", 
    torch_dtype=torch.float16
)
tokenizer = AutoTokenizer.from_pretrained(base_model_id)

# Apply the adapter
model = PeftModel.from_pretrained(model, "nnat03/biden-mistral-adapter")

# Generate a response
prompt = "What's your vision for America's future?"
input_text = f"<s>[INST] {prompt} [/INST]"
inputs = tokenizer(input_text, return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_length=512, temperature=0.7, do_sample=True)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response.split("[/INST]")[-1].strip())
```
