# Kevin - A Token Compressor for Long-Range Dependency Conversations

![Thumbnail](thumbnail.jpg)

## Model Details

### Model Description

This model is a fine-tuned version of the Llama 3.1 8B 4-bit model, specifically trained for token compression tasks. It uses LoRA (Low-Rank Adaptation) for efficient fine-tuning while maintaining the base model's performance.

- **Developed by:** Alosh Denny
- **Funded by:** TinkerSpace
- **Shared by** EmelinLabs
- **Model type:** Token Compressor for Memories
- **Language(s) (NLP):** English
- **License:** apache-2.0

## Uses

### Direct Use

This model is designed for token compression tasks. It can be used to generate more concise versions of input text while preserving the essential meaning.

### Downstream Use

The compressed outputs from this model can be used in various NLP applications where text length is a constraint, such as summarization, efficient text storage, or as input for other language models with token limits.

### Out-of-Scope Use

This model should not be used for tasks that require full preservation of the original text or where nuanced details are critical. It's not suitable for legal, medical, or other domains where precise wording is essential.

## Bias, Risks, and Limitations

- The model may inadvertently remove important context or nuance during compression.
- There might be biases inherited from the base Llama 3.1 model or introduced during fine-tuning.
- The model's performance may vary depending on the input text's domain or complexity.

### Recommendations

- Users should review the compressed outputs for accuracy and appropriateness before use in critical applications.
- It's advisable to test the model on a diverse range of inputs to understand its performance across different text types and domains.

## How to Get Started with the Model

Use the code below to get started with the model.

```python
from peft import PeftModel, PeftConfig
from transformers import AutoModelForCausalLM

config = PeftConfig.from_pretrained("aoxo/kevin-token-compressor")
base_model = AutoModelForCausalLM.from_pretrained("unsloth/Meta-Llama-3.1-8B-bnb-4bit")
model = PeftModel.from_pretrained(base_model, "aoxo/kevin-token-compressor")

#### Evaluation 2: News Article

**Input:**
```
ORLANDO, Fla. - A man who allegedly stole a swan boat and marooned himself on a fountain in the middle of a Florida lake told police he took a large quantity of MDMA and wanted to be with the swans that frequent the lake. According to an Orlando police report obtained by Orlando Weekly, 36-year-old Kyle Thurston said he wanted to be with the swans because "they don't judge him." At about 4 a.m. Friday, Orlando police came to Lake Eola and found Thurston sitting on the fountain screaming for help. Police said Thurston forgot to tie up the swan boat and it drifted off while he was on the fountain. When he returned to where he thought the boat would be and realized it was gone, he sat down on the fountain and started calling for help, police said. Orlando police are following up with the rental boat company to see if any charges will be filed.

**Output:**
```
In Orlando, a man on MDMA stole a swan boat and got stranded on a lake fountain, saying he wanted to be with the "non-judgmental" swans. Police found him screaming for help after the boat drifted away. Charges are under review.

```
You're indecisive and unpredictable, constantly changing moods—hot and cold, yes and no, in and out. Our relationship is a roller coaster of breakups and makeups, full of contradictions and emotional ups and downs. You don’t want to stay, but you don’t want to leave either.
