The **Nexiloop Nova-1.1B** model is a fine-tuned version of the Llama 2 architecture with **1.1B parameters**. It has been trained on over **3 trillion tokens** and is built to provide high-quality, efficient responses in a wide variety of conversational contexts.
|
51 |
+
|
52 |
+
### **Features:**
|
53 |
+
- **Optimized for Compact Systems:** With just 1.1B parameters, Nexiloop Nova is perfect for applications where memory and computation are limited.
|
54 |
+
- **Pretraining:** The model has been pre-trained on the **SlimPajama-627B** dataset, fine-tuned for even better conversational abilities.
|
55 |
+
|
56 |
+
### **Training Overview:**
|
57 |
+
We adopted the same architecture and tokenizer as **Llama 2**, which allows Nexiloop Nova to plug into many existing open-source projects. The training, which started on **2023-09-01**, used **16 A100-40G GPUs** to achieve remarkable optimization.
|
58 |
+
|
59 |
+
The model was initially fine-tuned on a variant of the **UltraChat** dataset, which consists of synthetic dialogues generated by **ChatGPT**. It was then further aligned using the **DPOTrainer** from **TRL**, utilizing a ranking dataset containing **64k prompts** and responses from **GPT-4**.

### **How to Use Nexiloop Nova Model**
|
64 |
+
|
65 |
+
To use Nexiloop Nova, you'll need **transformers>=4.34**. Below is a simple example showing how to integrate the model into your application.
|
66 |
+
|
67 |
+
#### Example Code:
|
68 |
+
|
69 |
+
```bash
|
70 |
+
# Install necessary libraries
|
71 |
+
pip install transformers==4.34
|
72 |
+
pip install accelerate
|
73 |
+
|
74 |
+
|
75 |
+
|
76 |
+
import torch
|
77 |
+
from transformers import pipeline
|
78 |
+
|
79 |
+
pipe = pipeline("text-generation", model="nexiloop/nova", torch_dtype=torch.bfloat16, device_map="auto")
|
80 |
+
|
81 |
+
# We use the tokenizer's chat template to format each message - see https://huggingface.co/docs/transformers/main/en/chat_templating
|
82 |
+
messages = [
|
83 |
+
{
|
84 |
+
"role": "system",
|
85 |
+
"content": "You are a friendly chatbot who always responds in the style of a pirate",
|
86 |
+
},
|
87 |
+
{"role": "user", "content": "How many helicopters can a human eat in one sitting?"},
|
88 |
+
]
|
89 |
+
prompt = pipe.tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
|
90 |
+
outputs = pipe(prompt, max_new_tokens=256, do_sample=True, temperature=0.7, top_k=50, top_p=0.95)
|
91 |
+
print(outputs[0]["generated_text"])
|
92 |
+
