# Zurich 7B GammaCorpus v2-100k
|
| 25 |
+
*A Qwen 2.5 model fine-tuned on the GammaCorpus dataset*
|
| 26 |
+
|
| 27 |
+
## Overview
|
| 28 |
+
Zurich 7B GammaCorpus v2-100k is a fine-tune of Alibaba's **Qwen 2.5 7B Instruct** model. Zurich is designed to outperform other models that have a similar size while also showcasing [GammaCorpus v2-100k](https://huggingface.co/datasets/rubenroy/GammaCorpus-v2-100k).
|
| 29 |
+
|
| 30 |
+
## Model Details
|
| 31 |
+
- **Base Model:** [Qwen/Qwen2.5-7B-Instruct](https://huggingface.co/Qwen/Qwen2.5-7B-Instruct)
|
| 32 |
+
- **Type:** Causal Language Models
|
| 33 |
+
- **Architecture:** Transformers with RoPE, SwiGLU, RMSNorm, and Attention QKV bias
|
| 34 |
+
- **Number of Parameters:** 7.61B
|
| 35 |
+
- **Number of Paramaters (Non-Embedding):** 6.53B
|
| 36 |
+
- **Number of Layers:** 28
|
| 37 |
+
- **Number of Attention Heads (GQA):** 28 for Q and 4 for KV
|
| 38 |
+
|
| 39 |
+
## Training Details
|
| 40 |
+
|
| 41 |
+
Zurich-7B-GCv2-100k underwent fine-tuning with 1 T4 GPU for ~70 minutes and trained with the [Unsloth](https://unsloth.ai/) framework. Zurich-7B-GCv2-100k was trained for **60 Epochs**.

+
|
| 43 |
+
## Usage
|
| 44 |
+
|
| 45 |
+
### Requirements
|
| 46 |
+
|
| 47 |
+
We **strongly** recommend you use the latest version of the `transformers` package. You may install it via `pip` as follows:
|
| 48 |
+
|
| 49 |
+
```
|
| 50 |
+
pip install transformers
|
| 51 |
+
```
|
| 52 |
+
|
| 53 |
+
### Quickstart
|
| 54 |
+
|
| 55 |
+
Here is a code snippet with `apply_chat_template` to show you how to load the tokenizer and model and how to generate contents;
|
| 56 |
+
|
| 57 |
+
```python
|
| 58 |
+
from transformers import AutoModelForCausalLM, AutoTokenizer
|
| 59 |
+
|
| 60 |
+
model_name = "rubenroy/Zurich-7b-GCv2-100k"
|
| 61 |
+
|
| 62 |
+
model = AutoModelForCausalLM.from_pretrained(
|
| 63 |
+
model_name,
|
| 64 |
+
torch_dtype="auto",
|
| 65 |
+
device_map="auto"
|
| 66 |
+
)
|
| 67 |
+
tokenizer = AutoTokenizer.from_pretrained(model_name)
|
| 68 |
+
|
| 69 |
+
prompt = "How tall is the Eiffel tower?"
|
| 70 |
+
messages = [
|
| 71 |
+
{"role": "system", "content": "You are Zurich, an AI assistant built on the Qwen 2.5 7b model developed by Alibaba Cloud, and fine-tuned by Ruben Roy. You are a helpful assistant."},
|
| 72 |
+
{"role": "user", "content": prompt}
|
| 73 |
+
]
|
| 74 |
+
text = tokenizer.apply_chat_template(
|
| 75 |
+
messages,
|
| 76 |
+
tokenize=False,
|
| 77 |
+
add_generation_prompt=True
|
| 78 |
+
)
|
| 79 |
+
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)
|
| 80 |
+
|
| 81 |
+
generated_ids = model.generate(
|
| 82 |
+
**model_inputs,
|
| 83 |
+
max_new_tokens=512
|
| 84 |
+
)
|
| 85 |
+
generated_ids = [
|
| 86 |
+
output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
|
| 87 |
+
]
|
| 88 |
+
|
| 89 |
+
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
|
| 90 |
+
```
