# Phi-3-mini-128K-instruct with CPO-SimPO
|
6 |
+
|
7 |
+
This repository contains the Phi-3-mini-128K-instruct model enhanced with the CPO-SimPO technique. CPO-SimPO combines Contrastive Preference Optimization (CPO) and Simple Preference Optimization (SimPO).
|
8 |
+
|
9 |
+
## Introduction
|
10 |
+
|
11 |
+
Phi-3-mini-128K-instruct is a model optimized for instruction-based tasks. This approach has demonstrated notable improvements in key benchmarks, pushing the boundaries of AI preference learning.
|
12 |
+
|
13 |
+
### What is CPO-SimPO?
|
14 |
+
|
15 |
+
CPO-SimPO is a novel technique, which combines elements from CPO and SimPO:
|
16 |
+
|
17 |
+
- **Contrastive Preference Optimization (CPO):** Adds a behavior cloning regularizer to ensure the model remains close to the preferred data distribution.
|
18 |
+
- **Simple Preference Optimization (SimPO):** Incorporates length normalization and target reward margins to prevent the generation of long but low-quality sequences.
|
19 |
+
|
20 |
+

+
## Model Performance
|
26 |
+
|
27 |
+
COMING SOON!
|
28 |
+
|
29 |
+
- **TruthfulQA:** 56.19
|
30 |
+
|
31 |
+
### Key Improvements:
|
32 |
+
- **Enhanced Model Performance:** Significant score improvements, particularly in GSM8K (up by 8.49 points!) and TruthfulQA (up by 2.07 points).
|
33 |
+
- **Quality Control:** Improved generation of high-quality sequences through length normalization and reward margins.
|
34 |
+
- **Balanced Optimization:** The BC regularizer helps maintain the integrity of learned preferences without deviating from the preferred data distribution.
|
35 |
+

+
## Usage
|
37 |
+
|
38 |
+
### Installation
|
39 |
+
|
40 |
+
To use this model, you need to install the `transformers` library from Hugging Face.
|
41 |
+
|
42 |
+
```bash
|
43 |
+
pip install transformers
|
44 |
+
```
|
45 |
+
|
46 |
+
### Inference
|
47 |
+
|
48 |
+
Here's an example of how to perform inference with the model:
|
49 |
+
|
50 |
+
```python
|
51 |
+
import torch
|
52 |
+
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
|
53 |
+
|
54 |
+
torch.random.manual_seed(0)
|
55 |
+
|
56 |
+
model = AutoModelForCausalLM.from_pretrained(
|
57 |
+
"Syed-Hasan-8503/Phi-3-mini-128K-instruct-cpo-simpo",
|
58 |
+
device_map="cuda",
|
59 |
+
torch_dtype="auto",
|
60 |
+
trust_remote_code=True,
|
61 |
+
)
|
62 |
+
tokenizer = AutoTokenizer.from_pretrained("Syed-Hasan-8503/Phi-3-mini-128K-instruct-cpo-simpo")
|
63 |
+
|
64 |
+
messages = [
|
65 |
+
{"role": "user", "content": "Can you provide ways to eat combinations of bananas and dragonfruits?"},
|
66 |
+
{"role": "assistant", "content": "Sure! Here are some ways to eat bananas and dragonfruits together: 1. Banana and dragonfruit smoothie: Blend bananas and dragonfruits together with some milk and honey. 2. Banana and dragonfruit salad: Mix sliced bananas and dragonfruits together with some lemon juice and honey."},
|
67 |
+
{"role": "user", "content": "What about solving an 2x + 3 = 7 equation?"},
|
68 |
+
]

+
pipe = pipeline(
|
71 |
+
"text-generation",
|
72 |
+
model=model,
|
73 |
+
tokenizer=tokenizer,
|
74 |
+
)
|
75 |
+
|
76 |
+
generation_args = {
|
77 |
+
"max_new_tokens": 500,
|
78 |

}
|
82 |
+
|

|
84 |
+
print(output[0]['generated_text'])
|

```
