# OpenLLaMa 3B PersonaChat
This is a LoRA finetune of [OpenLLaMa 3B](https://huggingface.co/openlm-research/open_llama_3b) on the [personachat-truecased](https://huggingface.co/datasets/bavard/personachat_truecased) dataset with 3 epochs of 500 steps.

## Use
Before using this model, you must first add these extra tokens:
```python
tokenizer.add_special_tokens({"additional_special_tokens": ["<|human|>", "<|bot|>", "<|endoftext|>"]})
model.resize_token_embeddings(len(tokenizer))
```
The model is finetuned with the format is as follows:
```
Personality:
 - [...]
 - [...]
<|human|>Hi there!<|endoftext|><|bot|>Hello!<|endoftext|>
```
To use this model, you must first define the personalities.
```python
personalities = """Personality:
 - [...]
 - [...]
"""
```
Then, follow the format:
```python
user = input(">>> ")
prompt = f"{personalities}<|human|>{user}<|endoftext|><|bot|>"
```
