# babelAI/opt-6.7b-lora

## Model Description

`babelAI/opt-6.7b-lora` is a variant of the OPT-6.7B model fine-tuned using LoRA (Low-Rank Adaptation) techniques. This model leverages the LoRA method to reduce the number of trainable parameters, allowing for efficient fine-tuning on domain-specific tasks without the need for extensive computational resources.

## Model Architecture

- **Base Model**: OPT-6.7B
- **Parameter Count**: 6.7 Billion
- **Fine-Tuning Method**: LoRA (Low-Rank Adaptation)

## Intended Use

This model is designed for a variety of natural language processing tasks, including but not limited to:

- Text generation
- Text completion
- Conversational AI
- Language translation

## How to Use

### Installation

First, ensure you have the `transformers` library installed:

```bash
pip install transformers
```

### Loading the Model

Here is an example of how to load and use the `babelAI/opt-6.7b-lora` model:

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

# Define the model ID
peft_model_id = "babelAI/opt-6.7b-lora"

# Load the configuration
config = PeftConfig.from_pretrained(peft_model_id)

# Define the quantization configuration for efficient loading
quantization_config = BitsAndBytesConfig(load_in_8bit=True)

# Load the base model with the quantization configuration
model = AutoModelForCausalLM.from_pretrained(
    config.base_model_name_or_path,
    return_dict=True,
    quantization_config=quantization_config,
    device_map='auto'
)

# Load the tokenizer
tokenizer = AutoTokenizer.from_pretrained(config.base_model_name_or_path)

# Load the LoRA model
model = PeftModel.from_pretrained(model, peft_model_id)

# Example usage
text = "Once upon a time"
inputs = tokenizer(text, return_tensors='pt')
outputs = model.generate(**inputs)
generated_text = tokenizer.decode(outputs[0], skip_special_tokens=True)

print(generated_text)
```

## Training Data

The model was fine-tuned on a diverse set of texts to ensure robust performance across different domains. The dataset includes a mixture of publicly available text corpora, including:

- Wikipedia
- Books
- News articles
- Conversational data

## Evaluation

The model was evaluated on several benchmarks to ensure its performance is up to standard. Below are some of the evaluation metrics:

- Perplexity on common text datasets
- Accuracy on specific language tasks
- Performance on custom benchmarks relevant to specific use cases

## Limitations and Biases

While `babelAI/opt-6.7b-lora` is a powerful model, it is important to be aware of its limitations:

- The model can generate biased or inappropriate content, reflecting biases present in the training data.
- It may not perform well on highly specialized or niche topics without further fine-tuning.
